Polypropylene Spunbond Nonwoven Fabric

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

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

From a Nonwoven Roll Manufacturer to the Grain Industry Walk into any bulk grain warehouse or supermarket rice aisle. What do you see?Mostly woven polypropylene bags. They’re strong, sure. But they have serious problems: frayed edges, rough texture, poor printing quality, and dust leakage. Now look at the premium segment. More and more rice mills and flour brands are switching to polypropylene spunbond nonwoven fabric. Why? Because it solves almost every pain point of traditional woven sacks. Here is why your next batch of rice or flour should go into a spunbond nonwoven bag.   1. No Dust Leakage (This is Huge for Flour) Woven PP bags are made of interlaced flat tapes. There are always tiny gaps. For rice, that might be fine. For flour? Fine dust escapes constantly—wasting product, dirtying trucks, and annoying warehouse staff. Spunbond nonwoven is made from continuous filaments bonded together. It has no weave gaps. Dust stays inside. Period. For flour mills, this alone is worth the switch.   2. Breathable but Blocks Pests Grains and flour need airflow to prevent mold and heat buildup. Spunbond nonwoven is naturally breathable—air circulates, moisture escapes. But the fabric's fine pore structure is still small enough to block insects and weevils. Traditional woven bags often let small pests in through the weave gaps. Spunbond doesn't.   3. Much Better Print Quality Woven PP bags print poorly—coarse, blurry, limited colors. Your brand deserves better.Spunbond nonwoven has a smooth, paper-like surface. It accepts high-quality flexo or gravure printing with sharp logos, bright colors, and even barcodes. Your bag becomes a real marketing tool, not just a container.   4. Softer on Hands & Equipment Woven edges are sharp. Workers loading trucks get cut fingers. Filling machines suffer from abrasive wear.Spunbond nonwoven is soft, smooth, and lint-free. It’s gentler on both human hands and automated filling lines.   5. Lightweight = Lower Shipping Cost A spunbond bag of the same strength weighs significantly less than a woven bag. When you're shipping 10,000 empty bags, the weight savings translate directly into lower freight costs. For high-volume grain exporters, this adds up fast.   6. Fully Recyclable Like woven PP, spunbond is 100% polypropylene. It can be recycled in existing PP streams. But unlike woven bags, there's no need to separate tapes or remove laminations. This makes end-of-life recycling simpler for mills with closed-loop programs.   7. Recommended Basis Weight: 80gsm and Above Not all spunbond is created equal. For grain and flour packaging, we strongly recommend using 80gsm or higher. Below 80gsm (e.g., 50–70gsm): Suitable for lightweight produce or bread bags, but may risk tearing under the weight and sharp corners of rice grains or flour settling during transport. 80gsm – 100gsm: The sweet spot for 5kg to 25kg bags. Excellent strength-to-weight ratio, durable enough for automated filling lines, yet still cost-effective. 100gsm – 120gsm: Recommended for 25kg to 50kg industrial-size bags or rough handling conditions (e.g., animal feed, long-distance export shipments). Using 80gsm+ spunbond ensures the bag withstands stacking, vibration, and accidental drops without seam failure or fabric rupture.     Who's Using Spunbond Grain Bags Already? Premium rice brands in Southeast Asia (5kg, 10kg sizes) – typically using 80–90gsm Organic flour mills in Europe (avoiding bleach in white woven bags) – using 90–100gsm Animal feed producers needing breathable, pest-proof small sacks – using 100–120gsm   What About Strength? Some buyers worry: "Is nonwoven strong enough for a 25kg rice bag?" Yes—with the right basis weight. Our spunbond rolls are available from 40gsm to 150gsm. For reliable grain and flour packaging, we consistently advise customers to start at 80gsm and above. Combined with reinforced bottom stitching (or ultrasonic welding), an 80gsm+ spunbond bag handles daily loading, stacking, and transport without issues.   The Bottom Line for Grain Processors Feature Woven PP Bag Spunbond Nonwoven Bag (80gsm+) Dust leakage Yes No Pest protection Moderate Excellent Print quality Poor Excellent Worker safety Sharp edges Soft Weight (empty) Heavy Light Recommended strength – 80gsm minimum Recycling Moderate Easy If you are a rice mill, flour producer, or packaging converter, spunbond nonwoven is not a niche product—it's a serious upgrade over traditional weaving. And with 80gsm or higher, you get proven durability without the drawbacks of woven sacks. We supply PP spunbond fabric in large rolls, available from 80gsm to 150gsm for grain packaging applications. White, natural, or custom colors. UV-stabilized options available for outdoor feed storage. Ready to test a sample roll at 80gsm or 100gsm? Contact us. Let's pack grain better.

  Dear Valued Customers and Partners, did you know that proper storage is a critical factor in preserving the superior performance of our polypropylene (PP) spunbond nonwoven fabric?    Incorrect storage conditions can lead to product aging, reduced fabric strength, or even render the material unusable, ultimately disrupting your production process and final product quality. To help you maximize the potential of our high-quality non-woven products, we have prepared this detailed scientific storage guide.   Core Storage Principles:   1. Palletize and Keep Off the Ground   Use Pallets: Always place all rolls or sheets on sturdy, flat wooden or plastic pallets. This not only prevents packaging damage but also effectively isolates moisture from the floor.   No Direct Ground Contact: Never stack products directly on the ground, as even concrete floors can become damp under certain conditions, posing a latent threat to the non-woven fabric.   2. Provide an Ideal Indoor Environment   Control Temperature & Humidity: The warehouse or storage room should be kept cool and dry. We recommend an ambient temperature between 15°C - 30°C and a relative humidity of 50% - 65%.   Ensure Good Ventilation: Maintain adequate air circulation to prevent stuffiness and moisture buildup. Ensure that vents do not introduce external dust.   3. Protect from UV Light and Heat   Avoid Sunlight/UV Rays: Ultraviolet (UV) light is the primary cause of polypropylene degradation. It is essential to store nonwoven fabric in a location completely shielded from direct sunlight. Windows should be covered with blackout curtains or UV-blocking film.   Keep Away from Heat Sources: Store products away from any heat sources such as radiators, boilers, or heaters, as sustained high temperatures can cause material deformation or performance degradation.   4. Follow Stacking Guidelines   Limit Stacking Height: Adhere to the maximum number of stacking layers indicated on the packaging. Over-stacking can exert excessive pressure on the bottom rolls, causing permanent deformation and issues in subsequent processing.   Practice FIFO (First-In, First-Out): Establish and strictly follow a FIFO inventory management system. This ensures that the oldest stock is used first, preventing natural aging due to prolonged storage.   Conclusion: By following these simple storage principles, you can significantly extend the service life of your PP spunbonded nonwoven fabric, and ensure its consistent performance.   Proper storage is not only a protection for the product but also a safeguard for your production efficiency. If you have any questions regarding storage for specific application environments, please feel free to contact our technical team. Henghua Nonwoven are always here to help.
