The core differences of PP spunbond nonwoven fabric with different weight are concentrated in three dimensions: physical properties, applicable scenarios, and procurement costs. Based on your previous selection needs, the specific differences are as follows: 1、 Core performance differences 1. Low weight (9-30g/㎡): The fabric is lightweight, highly breathable, with low tensile strength, overall soft feel, light weight per unit area, and almost no stiffness. 2. Medium weight (30-80g/㎡): Balanced performance, balancing breathability and tensile strength, flat and uniform fabric surface, with basic stiffness, making it the most widely used mainstream range in the market. 3. High weight (80-150g/㎡): The fabric surface is thick, with high tensile and tear strength, strong load-bearing capacity, and good stiffness. Some high weight products have a harder hand feel and are more difficult to fold and store. 2、 Differences in applicable scenarios 1.9-30g/㎡: Communication cable core wrapping, disposable mask surface, agricultural ultra-thin seedling covering cloth, only suitable for extremely lightweight wrapping and protective scenarios. 2.30-80g/㎡: ordinary shopping bags, medical isolation gowns, diaper surface, home bed sheets, are the main selection range for daily civilian and conventional sanitary materials. 3.80-150g/㎡: Suitable for industrial scenarios that require high load-bearing and wear resistance, including load-bearing shopping bags, geotextiles, automotive interiors, and engineering protective materials. 3、 Cost and processing differences The higher the weight, the more raw materials are consumed per square meter, and the purchasing unit price increases synchronously. Although the ton price of 120g/㎡ products is close to that of low weight products, the cost per square meter is six times that of 20g/㎡ products. 2. Fabrics with excessive weight (>120g/㎡) will become harder, and the heat sealed edges are prone to brittleness and cracking, requiring higher adaptability for downstream bag making and laminating equipment.

There is no unified universal mandatory national standard for the tensile strength and elongation of PP spunbond nonwoven fabric. The core indicators vary significantly with weight and application scenarios, and there are clear testing execution standards. The specific benchmarks are as follows: 1、 Core Test Execution Standards The industry standard for testing is GB/T 24218.3 or GB/T 3923.1-2013, corresponding to international standards ISO 13934-1 and ASTM D5035. The testing requires taking samples from both the longitudinal (MD) and transverse (CD) directions for testing. 2、 Benchmark indicators for conventional products of different weights 1.15g/㎡ conventional spunbond fabric: longitudinal tensile strength of about 30N/5cm, elongation at break of 90% -100% 2.40g/㎡ ordinary spunbond PP fabric: longitudinal tensile strength of about 85N/5cm, transverse strength of about 72N/5cm, elongation at break of about 25% 3.50g/㎡ conventional spunbond fabric: longitudinal tensile strength can reach 124N/5cm 4.150g/㎡ industrial grade geotextile: The national standard requires a longitudinal fracture strength of ≥ 9.0kN/m 3、 Industry requirements for special scenarios 1. Ordinary conventional PP spunbond non-woven fabric: The elongation at break is generally in the range of 90% -100%, and the ductility is excellent 2. Medical protective scenarios: It is necessary to balance tension and high elongation to avoid clothing tearing during wearing and activities 3. Common problems with inferior products: Some manufacturers excessively add filler masterbatch to increase tensile strength, which can lead to extremely low elongation at break, brittle materials, and easy tearing and damage in actual use. When purchasing, both indicators need to be verified at the same time, not just the tensile strength. Contact us for samples or a quote

    Walk into any cleanroom, pharmaceutical factory, or medical device assembly line. Look at the packaging materials used for sterile instruments, syringes, or sensitive electronic components. You'll likely see a familiar material: polypropylene spunbond nonwoven fabric. Why is spunbond so widely used in cleanroom and medical packaging? The answer comes down to four key properties: lint-free, dust-proof, hydrophobic, and sterilizable. In this article, we'll explore why PP spunbond is the go-to material for packaging in critical environments. What Makes PP Spunbond Ideal for Cleanroom and Medical Packaging? Cleanrooms and medical device packaging have strict requirements. Any contamination — dust, fibers, moisture, or particles — can compromise product safety or performance. Here's how PP spunbond meets these requirements: RequirementHow PP Spunbond Delivers Lint-free Continuous filaments — no loose fibers, no frayed edges Dust-proof Dense, random filament structure blocks fine dust particles Hydrophobic (water-repellent) Naturally repels moisture — keeps contents dry and clean Low particulate No shedding, minimal contamination risk Sterilizable Compatible with EtO, gamma, and E-beam sterilization Breathable Allows sterilization gases to penetrate (critical for EtO) Key Packaging Applications 1. Sterile Barrier Packaging (Medical Devices)For syringes, catheters, surgical instruments, and implants, spunbond nonwoven is used as the porous layer in sterile pouches (often combined with a film layer). It allows sterilizing gases (EtO) to penetrate while keeping out dust and bacteria. Why it works: Breathable for sterilization, but dust-proof and lint-free Typical spec: 30–60gsm, white 2. Cleanroom Wipes & Protective CoversIn cleanrooms, spunbond fabric is used as a protective cover for equipment, instruments, and work surfaces. It prevents dust from settling on critical items and is easily disposable. Why it works: Lint-free and low-particulate — doesn't contaminate the cleanroom Typical spec: 20–50gsm, white 3. Sterilization Wrap / Peel Pouch BackingSpunbond is commonly used as the breathable side of sterilization pouches. It allows EtO or steam to pass through while providing a bacterial barrier. Why it works: Breathable, sterilizable, and can be heat-sealed Typical spec: 40–70gsm, white 4. Equipment Covers (Medical and Industrial)In operating rooms and medical device assembly lines, spunbond is used to cover equipment between uses. It protects sensitive devices from dust, moisture, and contamination. Why it works: Hydrophobic (repels liquids) and dust-proof Typical spec: 30–60gsm, white or blue 5. Electronics Packaging (Anti-Static Options)For sensitive electronic components, spunbond packaging prevents dust contamination and, with antistatic additives, can also prevent static discharge. Why it works: Dust-proof, low-particulate, and customizable with additives Typical spec: 20–50gsm, white or pink (antistatic) Why Hydrophobic (Water-Repellent) Matters Unlike many other nonwoven materials (like cotton, paper, or cellulose-based fabrics), PP spunbond is naturally hydrophobic — it repels water. In cleanroom and medical packaging, this is a critical advantage: It does not absorb moisture — no swelling, no degradation It maintains structural integrity in humid environments It repels liquids — any accidental spills bead up and roll off It does not support mold or bacterial growth — unlike paper or cotton For packaging that protects sensitive medical devices or electronic components, this hydrophobic property is non-negotiable. Key distinction: Our single-layer PP spunbond is hydrophobic by default. It does not absorb water, making it ideal for moisture-sensitive packaging applications. (If you need hydrophilic fabric for wipes or absorbent layers, we can also offer surface treatment.) Spunbond vs. Other Cleanroom Packaging Materials PropertyPP SpunbondPaperCotton/Poly WovenPlastic Film Lint-free ✓ Yes No (sheds fibers) No (frays) ✓ Yes Dust-proof ✓ Yes Moderate Poor (gaps) ✓ Yes Hydrophobic ✓ Yes No (absorbs) Moderate ✓ Yes Breathable ✓ Yes Moderate Yes No (must perforate) Sterilizable (EtO) ✓ Yes Yes Yes Moderate Cost ✓ Low Low High Medium PP spunbond offers the unique combination of lint-free, dust-proof, hydrophobic, and breathable — a balance that paper and films simply cannot match.

1、 Complete production process 1. Raw material pretreatment: Mix polypropylene particles with antibacterial masterbatch such as nano zirconium phosphate loaded with silver in precise proportions, and remove moisture through hot air drying to avoid the formation of bubbles during subsequent melting processes that may affect spinning quality. 2‌. Melt extrusion: The mixed raw materials are fed into a screw extruder and heated to melt and plasticize in the temperature range of 220-250 ℃. The melt is then transported to the spinning component through a metering pump at a constant quantity and pressure. 3. Spinning into a web: The melt is extruded through the micropores of the spinneret to form continuous filaments, which are drawn by high-speed airflow and evenly laid on a moving web curtain to form a fiber web. 4. Reinforcement molding: The fiber mesh is reinforced by hot bonding using a hot rolling mill. Some high-end products are equipped with a water jet/needle punching composite process to ensure that the antibacterial components are evenly attached to the inside of the fiber, avoiding rapid loss during subsequent use. 5. Post treatment and finished product: After cooling and shaping, performance verification, the product is cut and rolled according to the specified width to obtain the final product. The qualified product can still maintain a stable antibacterial rate after 5 water washes. 2、 Core application areas 1‌. In the field of medical protection, it is used to make disposable surgical gowns, sterilization bags, inner layers of medical masks, and surgical drapes. It can effectively inhibit the growth of pathogenic bacteria, reduce the risk of cross infection, and comply with the GB/T20944.3 medical antibacterial material standard. 2. In the field of hygiene for mother and baby: As the surface layer of diapers, the bottom fabric of sanitary napkins, and the base material of urine pads, it is skin friendly and non irritating, avoiding the proliferation of bacteria in intimate use scenarios and improving the hygiene of use. 3‌. Household daily use areas: pet pads, antibacterial and dust removal wiping cloths, home textile lining, can suppress odors and mold growth, suitable for damp and prone to bacterial growth in home scenes. 4‌. In the field of industrial filtration, spunbond filtration substrates for fresh air systems and air conditioners are used to prevent bacterial adhesion and mold growth after long-term use, thereby improving the hygiene level of air filtration.

As of August 21, 2026, public information shows that PP raw material prices are relatively strong, but downstream demand for PP non-woven fabrics is still weak, and the market is in a stage of "cost support, demand game". 1. PP raw material prices continue to rise According to data from Shengyi Society, the reference price for PP wire drawing on August 21st was 9216.67 yuan/ton, an increase of 2.71% from 8973.33 yuan/ton on August 1st. On August 19th, the mainstream price of PP wire drawing in Qingzhou market was about 9150-9250 yuan/ton. The current price support mainly comes from the strengthening of crude oil and propylene costs, as well as some equipment maintenance; However, the downstream delivery efforts are insufficient, and the continued significant increase in prices still requires demand coordination. 2. The industry's operating rate is at a relatively low level The operating rate of the PP non-woven fabric industry in July 2026 was about 38.14%, a decrease of 2.48 percentage points from the previous period. The demand shows obvious differentiation: 1. The demand for takeaway insulated bags and packaging non-woven fabrics is relatively acceptable; 2. The demand for sanitary materials such as diapers has decreased; 3. Industrial and agricultural products such as geotextile, waterproof cloth, covering cloth, and seedling raising cloth are in the off-season. 3. Market judgment: Short term cost push, future demand dependent The main contradictions in the current industry can be summarized as follows: PP raw material price increase → spunbond non-woven fabric cost increase → factory pressure to raise prices; But insufficient terminal orders → cautious downstream procurement → limited transmission of price increases. 4. Actual impact on production and export enterprises: 1. The competition for regular white and low weight products is still fierce, and simply following the price increase of raw materials can easily lead to losing orders. 2. Packaging bags, insulation bags, furniture packaging, medical protection, and high-strength composite materials are more worthy of attention. 3. It is recommended to use a valid quotation and include a clause for PP raw material price fluctuations in the bulk order. 4. In foreign trade development, emphasis should be placed on weight stability, tensile strength, uniformity, color consistency, and delivery time, rather than just quoting low prices.   Contact us for samples or a quote

    Walk through any modern farm or greenhouse, and you'll see something that wasn't common a generation ago: fabric covering the soil, protecting the crops, and shielding plants from the elements. That fabric is often polypropylene spunbond nonwoven — and it has become one of the most versatile tools in modern agriculture. From protecting young seedlings from frost to suppressing weeds without chemicals, PP spunbond is helping farmers grow more food with fewer inputs. In this guide, we'll explore the key agricultural applications of PP spunbond nonwoven and how to choose the right fabric for your farm. Why Agriculture Loves PP Spunbond Nonwoven Farmers are practical people. They choose materials that work — and PP spunbond works. Here's why: PropertyAgricultural Benefit Breathable Allows air and moisture to reach plants while covering them UV stabilized Withstands months of outdoor sun exposure Lightweight Easy to lay, move, and store — no heavy equipment needed Durable Resists tearing during installation and windy conditions Permeable Lets rainwater through — no pooling or runoff Chemical-free Reduces need for herbicides and pesticides Cost-effective Lower cost than woven alternatives or plastic films Key Agricultural Applications 1. Crop Covers (Floating Row Covers)Spunbond fabric is laid directly over rows of young plants. It acts as a micro-climate — trapping heat, blocking wind, and protecting against light frosts. Benefits: Earlier harvest, higher yields, less pest damage Common crops: Lettuce, spinach, strawberries, melons, tomatoes Typical spec: 15–30gsm, white or light-colored (to reflect heat) 2. Weed Mats (Ground Cover / Mulch Fabric)Black spunbond fabric is laid on the soil surface around plants. It blocks sunlight from reaching weed seeds, preventing germination — without chemicals. Benefits: No herbicides, less labor (no hand-weeding), retains soil moisture Common uses: Vegetable beds, fruit orchards, vineyards, nursery pots Typical spec: 50–100gsm, black, UV stabilized 3. Frost ProtectionLightweight spunbond creates a protective blanket that traps daytime heat and protects plants from freezing overnight. It can provide 2–4°C of frost protection. Benefits: Extends growing season, protects early and late crops Common crops: Young seedlings, flowers, fruit trees in bloom Typical spec: 17–30gsm, white, lightweight and breathable 4. Insect Protection (Insect Netting Alternative)Spunbond fabric acts as a physical barrier against insects — blocking aphids, whiteflies, and other pests without chemicals. Benefits: Reduces pesticide use, protects organic crops Typical spec: 15–25gsm, white or fine-weave 5. Greenhouse Internal CoversInside greenhouses, spunbond is used as a secondary thermal layer — reducing heating costs and providing shade during hot weather. Benefits: Lower energy costs, temperature control Typical spec: 30–50gsm, white or grey 6. Seedling & Nursery ProtectionIn nurseries, spunbond covers protect young seedlings from wind, sunburn, and dry conditions until they are strong enough to transplant. Benefits: Higher survival rates, faster establishment Typical spec: 17–30gsm, white 7. Fruit Tree & Vineyard CoversFor orchards and vineyards, spunbond protects fruit from hail, birds, and sunburn — while still allowing air and light to reach the fruit. Benefits: Higher quality fruit, less waste Typical spec: 30–70gsm, white or black, UV stabilized Most popular agricultural spec: 17gsm white for crop covers and 50–80gsm black for weed mats. Weed Mats vs. Plastic Film — Why Spunbond Wins PropertyBlack Plastic FilmPP Spunbond Weed Mat Weed suppression ✓ Excellent ✓ Excellent Breathable (air + moisture) No (seals soil) ✓ Yes Rainwater penetration No (must be slitted) ✓ Yes (porous) Soil cooling effect Can overheat soil ✓ Moderate Durability in field Tears easily, UV degrades ✓ Tear-resistant, UV stable Reusability Usually single-use ✓ Multiple seasons End of life Hard to recycle, often burned ✓ 100% PP — recyclable Soil health impact Can degrade soil structure ✓ Maintains soil health Bottom line: Plastic film is cheaper upfront but damages soil health. Spunbond weed mats cost more initially but pay off over multiple seasons — and they're better for your soil. How to Choose the Right Agricultural Spunbond Here are the key factors to consider when specifying agricultural spunbond: 1. GSM (Weight) Light (15–30gsm): Crop covers, frost protection, insect barriers Medium (30–60gsm): Greenhouses, seedling protection, light weed suppression Heavy (60–100gsm): Weed mats, orchard covers, long-term ground cover 2. Color White: Reflects heat, good for crop covers and frost protection Black: Absorbs heat, blocks light — best for weed mats Green / Brown: Aesthetic preference for landscaping or orchards 3. UV Stabilization For outdoor use: UV stabilizers are essential. Without them, fabric degrades in 2–6 months. With them, it lasts 1–3 years outdoors. For greenhouse use: UV stabilization is less critical but still recommended 4. Width Agricultural spunbond is available in various widths — standard rolls are 1.6m, 2.0m, 2.4m, or custom widths to match your rows or beds Recommended Specs by Application ApplicationRecommended GSMColorUV Stabilization Floating row cover 15–25 White Recommended Frost protection 17–30 White Recommended Insect barrier 15–25 White Optional Weed mat (light) 50–70 Black Essential Weed mat (heavy) 80–100 Black Essential Orchard ground cover 70–100 Black Essential Greenhouse thermal layer 30–50 White / Grey Optional What We Offer for Agriculture At Heng Hua Nonwoven, we supply single-layer PP spunbond for agricultural applications: Basis weight: 15–100gsm (covering all agricultural uses) Width: Customizable up to 2.4m Color: White, black, green, brown — or custom colors UV stabilization: Standard for all outdoor grades Quality: ISO 9001:2015 certified; SVHC tested Our agricultural grades are designed for: 1–3 years of outdoor UV exposure Breathability for healthy plant growth Durability for multiple seasons of use The Bottom Line PP spunbond nonwoven is transforming modern agriculture.

Based on the continuous attention paid to the domestic market situation and peak season price trend of PP spunbond nonwoven fabric from July to September 2026, the geopolitical conflict between Israel and Iran will have a chain effect on the PP spunbond nonwoven fabric foreign trade market from three dimensions: raw material side, logistics side, and demand side, as follows: 1、 Upstream raw material transmission impact Iran is an important global crude oil exporting country, and the escalation of geopolitical conflicts will directly push up international crude oil prices, driving up the cost of polypropylene (PP) raw materials. The production cost of PP spunbond non-woven fabrics in China will passively rise, and the cost support of foreign trade quotations will be further strengthened. If the shipping passage through the Strait of Hormuz is blocked, there will be a short-term interruption in the export of PP raw materials in the Middle East region, and the global spot supply of polypropylene will be tight. The overall price center of PP spunbond nonwoven fabrics in the international market will also move up synchronously. 2、 International logistics impact 1. The shipping risks of the Red Sea and Persian Gulf routes around the conflict zone have increased, resulting in higher sea freight premiums and detour costs. The logistics cycle of PP spunbond non-woven fabrics exported from China to the Middle East and Europe has been extended, and the estimated logistics cost per container is expected to rise by 10% -20%. The delivery cost of foreign trade orders has significantly increased. 2. Some shipping companies may temporarily adjust their routes, resulting in a decrease in customs clearance efficiency at ports in the Middle East region, increased uncertainty in the delivery of foreign trade orders, and the need to reserve additional buffer time for long delivery cycles. 3、 The impact of foreign trade demand and order structure 1. The production capacity of conventional civilian PP spunbond nonwoven fabrics in the Middle East has been affected by conflicts, resulting in a decline in operating rates. Imported essential orders in the region will be transferred to stable supply countries such as China, and domestic foreign trade enterprises can undertake some incremental orders. 2. The European market is affected by fluctuations in energy prices, leading to further increases in local non-woven production costs. As a result, there will be a greater shift towards purchasing cost-effective Chinese made functional PP spunbond nonwoven fabrics. The proportion of export orders for high-end categories such as antibacterial and UV resistant fabrics in China is expected to further increase. 4、 Potential risk warning If the conflict escalates beyond expectations and the global commodity market experiences severe fluctuations, PP raw material prices may experience irrational surges, and the pricing risk of long-term foreign trade orders will significantly increase. It is recommended to set up raw material price linkage clauses when signing new orders to avoid cost fluctuations and losses. 5、 The above analysis is based on the current public geopolitical dynamics, and the degree of impact will be adjusted according to changes in the conflict situation. It is recommended to track the latest developments in crude oil prices and shipping routes in real time and adjust foreign trade order strategies in a timely manner.

Based on the market situation of PP spunbond nonwoven fabric in July and August 2026, as well as the relevant background of the Golden September and Silver October peak seasons, it is highly likely that the price of PP spunbond nonwoven fabric will experience a temporary slight increase in September 2026, but the possibility of a significant surge is low. The specific judgment criteria are as follows: 1、 The core factors supporting the upward trend of prices 1‌. Demand side recovery: September is the traditional "golden nine and silver ten" peak season in the industry, and the centralized replenishment demand for downstream agricultural autumn plowing cold proof fabrics, engineering geotextiles, and sanitary materials will be released. Currently, in August, some downstream customers have started pre stocking ahead of schedule, and demand side support has significantly increased. 2‌. Cost side support: Since August, the price of upstream polypropylene raw materials has risen narrowly, providing a cost floor for non-woven fabric production. Manufacturers currently have no room for significant price reductions, and some small and medium-sized factories have begun to slightly increase their offer prices. 3. Supply side constraints: The overall operating rate of the industry remains relatively low at around 38%, and spot inventory is within a reasonable range after being depleted in July and August, making it difficult for excess supply to suppress prices. 2、 Factors that restrict significant price increases 1. The overall new production capacity of the industry is still being continuously released, and the overall market supply is sufficient, without a serious shortage of goods. 2. Downstream terminals are highly sensitive to prices. If the price increase is too large, downstream procurement will quickly turn to wait-and-see, and it will be difficult to sustain high volume of actual transactions. 3、 Market forecast The mainstream price of PP spunbond non-woven fabric in September is likely to see a slight increase of 200-500 yuan/ton compared to August, maintaining a stable and moderate upward trend overall, and there will be no unilateral sharp rise in the market. For first-time purchases, prices can be locked and stocked in batches according to demand from the end of August to early September.

  One of the most common questions buyers ask is: "What GSM (grams per square meter) should I choose for my spunbond nonwoven fabric?" It's a great question — because the answer determines everything: strength, durability, cost, and whether the fabric will actually perform in your application. Choose too low a GSM, and your fabric may tear, leak, or fail. Choose too high a GSM, and you're paying for material you don't need. In this guide, we'll break down the GSM range for PP spunbond nonwoven and match each weight range to the applications where it works best. What Does GSM Mean? GSM stands for grams per square meter. It is the standard measure of fabric weight in the nonwoven industry. Simply put: GSM RangeFabric TypeTypical Thickness 10–30gsm Very lightweight Very thin (tissue-like) 30–60gsm Lightweight Thin, flexible 60–100gsm Medium weight Moderate, balanced 100–150gsm Heavyweight Thicker, more rigid 150+gsm Extra heavy Very thick, felt-like Key rule: Higher GSM = stronger, heavier, more durable, and more expensive. Lower GSM = lighter, more flexible, less expensive, but less durable. GSM Selection Guide — By Application Here is our practical guide to choosing GSM based on your specific application: 10–30 GSM — Ultra-Lightweight Applications: Bouffant caps (hair covers), surgical masks (outer/inner layers), shoe covers, lightweight wipes Properties: Extremely thin, highly breathable, low cost, single-use Tip: For 30gsm and below, we recommend NOT rewinding to smaller cores — the fabric is too delicate 30–60 GSM — Lightweight Applications: Medical isolation gowns (Level 1), examination table covers, disposable wipes, produce bags, flower sleeves, lightweight shopping bags Properties: Soft, breathable, good balance of strength and flexibility Tip: Most common range for hygiene and medical disposables 60–100 GSM — Medium Weight Applications: Isolation gowns (Level 2–3), dust covers (furniture), spring wrap, agricultural ground covers, reusable shopping bags, sterile packaging Properties: Good strength, good tear resistance, balanced cost Tip: The "sweet spot" for many industrial and packaging applications 100–150 GSM — Heavyweight Applications: Heavy-duty rice/flour bags (25–50kg), geotextiles, automotive interior trim, wheel arch liners, underbody shields, furniture dust covers (heavy-duty) Properties: High strength, high puncture resistance, good abrasion resistance Tip: Recommended for applications requiring high durability and load-bearing capacity 150+ GSM — Extra Heavyweight Applications: Heavy-duty geotextiles (road base, railway ballast), industrial protection, heavy-duty tarpaulins Properties: Maximum strength, rigidity, durability Tip: We supply up to 150gsm; for above 150gsm, consider needle-punch or composite materials Quick Reference Table — GSM by Application ApplicationRecommended GSMKey Requirements Bouffant cap 10–15 Lightweight, breathable Surgical mask (outer/inner) 20–25 Soft, lint-free Shoe cover 25–35 Tear-resistant Exam table cover 30–40 Smooth, fluid-repellent Isolation gown (Level 1) 25–35 Balance of strength and comfort Isolation gown (Level 2–3) 35–50 Higher fluid resistance Flower sleeve 20–35 Breathable, attractive Produce bag (fruit/veg) 30–50 Breathable, printable Dust cover (furniture) 80–120 Tear-resistant, black Spring wrap (furniture) 60–90 Noise reduction, durable Rice/flour bag (5–25kg) 80–100 Strength, print quality Rice/flour bag (25–50kg) 100–120 High load capacity Geotextile (drainage) 80–150 Permeability, strength Automotive interior trim 80–120 Low odor, UV stability Agricultural ground cover 80–120 UV stabilized, durable How to Test If You've Chosen the Right GSM If you're unsure, here's a simple approach: Start with industry benchmarks — use the table above as a starting point Order sample rolls — test 2–3 GSM options in your production line Run performance tests — check tear strength, puncture resistance, and print quality Calculate cost per unit — compare material cost vs. performance gain Check with your supplier — we can recommend based on similar applications Pro tip: When switching from woven to spunbond, you can often use a lower GSM because spunbond's continuous filament structure provides better uniform strength than woven tapes. Common Mistakes When Choosing GSM Mistake 1: Choosing the lowest GSM to save moneyIf the fabric is too thin for the application, it will fail in use — causing product loss, customer complaints, and reputational damage. The savings are not worth the risk. Mistake 2: Choosing a higher GSM "just to be safe"You may be paying for unnecessary material. A 100gsm fabric may do exactly what a 120gsm fabric can do — for less cost. Mistake 3: Not considering the print weightHeavy ink coverage adds stiffness and can affect how the fabric handles. Consider print coverage when selecting GSM. Mistake 4: Ignoring your converting equipmentSome bag-making or converting machines have tension limits. Very light GSM may stretch or tear on high-speed lines. Very heavy GSM may be too stiff to feed smoothly. GSM and Cost — What's the Relationship? Higher GSM means more material per square meter. The cost per roll increases with GSM. But the cost per finished product depends on the size of the bag or part. GSMRelative Material CostRelative Strength 30gsm Base (1x) Low 50gsm 1.7x Medium 80gsm 2.7x High 120gsm 4x Very high The actual cost difference depends on roll width, order quantity, and market prices. We always recommend checking the cost per finished unit — not just the cost per kilogram of fabric.

The core application scenarios of PP spunbond nonwoven fabric in the medical field are as follows: 1、 Protective consumables As the outer layer of disposable medical masks, ordinary medical protective clothing, and isolation gowns, it has the characteristics of breathability and blocking the penetration of body fluids, which can effectively prevent droplets and pollutants from coming into contact. It is the basic material of the medical protection system. 2、 Disinfection packaging category Used for making sterilization packaging for surgical instruments, it is resistant to high temperatures and can be repeatedly disinfected. It can maintain the sterile state of the instruments after sterilization, avoid secondary contamination, and comply with the sterile packaging standards of the medical industry. 3、 Wound care category As a base material for medical dressings, disposable surgical drapes, and medical bed sheets, it is skin friendly and non irritating. It can absorb wound exudate and isolate external bacterial invasion, reducing the risk of postoperative infection. 4、 Upgraded feature application Antibacterial modified PP spunbond non-woven fabric can further enhance the antibacterial ability of medical scenarios, and is suitable for sub scenarios with stricter hygiene requirements such as high-level protection and maternal and child medical care. 5、 Some medical grade products have passed authoritative certifications such as SGS, possessing the characteristics of bi-directional stretching and high-temperature non adhesion, fully meeting the compliance requirements for medical use.

The process flow of PP spunbond non-woven fabric is as follows: 1、 Raw material preparation Put the polypropylene slices into the hopper, add antibacterial, UV resistant and other functional masterbatch as needed, mix evenly, and then send them into the extruder. 2、 Melt extrusion The material is heated to 220-250 ℃ in the extruder and completely melted, and then precisely transported to the spinning box through a metering pump. 3、 Spinning into a net The melt is extruded from the micropores of the spinning plate to form long filaments, which are drawn by high-speed airflow and evenly spread on the moving mesh curtain to form a fiber web. 4、 Reinforced molding By using the hot rollers of the hot rolling mill to heat bond and reinforce the fiber web, the fibers are bonded together to form a continuous non-woven fabric. 5、 Post processing roll up After cooling and shaping, surface treatment (hydrophilic and anti-static modification as needed), cutting according to the specified width, and finally winding to obtain the finished product. In addition, the PP spunbond nonwoven fabric produced by this process has a long filament structure and better mechanical strength than short fiber nonwoven fabrics, making it suitable for various functional modification scenarios that you are concerned about.

  You're a farmer with fresh-picked apples. Or a florist shipping roses across the country. Or a chemical manufacturer bagging hygroscopic materials. What do all these scenarios have in common? They all need breathable packaging. And for breathable packaging, polypropylene spunbond nonwoven fabric is one of the smartest choices available. Let's explore why. What Is Breathable Packaging? Breathable packaging allows air and moisture vapor to pass through the material while containing the contents. This is critical for products that: Need to breathe to stay fresh (fruits, vegetables, flowers) Release moisture or heat during storage (agricultural products) Need to avoid condensation (electronics, industrial parts) Are moisture-sensitive (certain powders, chemicals) Why PP Spunbond for Breathable Packaging? PropertyHow It Helps Controlled breathability Allows air circulation to extend shelf life Moisture release Prevents condensation and mold growth Lightweight Reduces shipping weight and cost Durable Resists tearing during handling and transport Printable Brand and label directly on the bag Food-safe Virgin PP is safe for food contact applications Recyclable 100% PP — compatible with recycling streams Fresh Produce & Agricultural Packaging This is where breathable packaging shines. Fruits and vegetables are alive after harvest — they respire, release moisture, and generate heat. Trapped moisture causes mold. No airflow accelerates spoilage. Common produce bags: 🍎 Apples, pears 🥔 Potatoes, onions, garlic 🍊 Citrus fruits 🥕 Root vegetables (carrots, parsnips) 🌾 Grains, pulses, beans Why spunbond? Allows CO₂ and ethylene gas to escape (prevents premature ripening) Lets moisture vapor out (prevents mold and rotting) Protects from dust and physical damage Lightweight for bulk shipping Typical spec: 30–60gsm, white or colors, printed with branding Flower & Horticulture Packaging Fresh-cut flowers are delicate. They need: Air circulation to prevent ethylene buildup (which causes wilting) Moisture control to prevent condensation on petals Protection from physical damage during shipping Spunbond nonwoven sleeves and wraps provide all of these — and they can be printed with branding. Typical spec: 20–40gsm, white or colors Industrial & Chemical Packaging Some industrial products require breathable packaging for safety or quality reasons: Hygroscopic powders — absorb moisture, must breathe to prevent clumping Chemicals that off-gas — need ventilation to prevent pressure buildup Construction materials — cement, lime, gypsum need to release moisture Feed and seed packaging — needs airflow to prevent mold Typical spec: 60–100gsm, white or custom colors Spunbond vs. Film vs. Woven for Breathable Packaging PropertyPP SpunbondPlastic FilmWoven PP Bag Breathability ✓ Excellent None (must perforate) Moderate Print quality ✓ Excellent Good Poor Dust blocking ✓ Excellent ✓ Excellent Poor Softness ✓ Soft Medium Rough Tear strength Good Poor (tears easily once punctured) ✓ Good Cost ✓ Low Low Medium Recyclable ✓ Yes ✓ Yes ✓ Yes Key advantage: Film bags must be perforated to allow airflow. Perforations create weak points, reduce strength, and still don't breathe as evenly as spunbond. Spunbond is naturally breathable across the entire surface.
