Detailed indicators of PP spunbond nonwoven fabrics with different weights

The detailed indicators of PP spunbond nonwoven fabrics with different weights can be sorted out in three mainstream ranges: light weight, medium weight, and high weight, covering key dimensions such as core physical properties and applicable scenarios. The specific details are as follows:

1. 17-30g/㎡ lightweight core specifications

1. Unit area mass deviation: ≤± 5%
2. Longitudinal tensile strength: 20-40N/5cm
3. Lateral tensile strength: 15-30N/5cm
4. Fracture elongation: 80% -120%
5. Core features: Lightweight and high transparency, can increase surface temperature by 2-3 ℃
6. Typical uses: early spring seedling frost prevention, disposable mask outer layer, cable core wrapping

2. 40-60g/㎡ medium-sized model core indicators

1. Unit area mass deviation: ≤± 5%
2. Longitudinal tensile strength: 60-100N/5cm
3. Lateral tensile strength: 50-80N/5cm
4. Tensile elongation at break: 60% -100%
5. Core features: Balanced breathability and strength, good printing adhesion
6. Typical uses: ordinary shopping bags, medical isolation gowns, greenhouse double insulation curtains

3. 80-120g/㎡ High Weight Heavy Duty Core Index

1. Unit area mass deviation: ≤± 5%
2. Longitudinal tensile strength: 120-200N/5cm
3. Lateral tensile strength: 100-180N/5cm
4. Fracture elongation: 40% -80%
5. Core Features: High tensile and tear resistance, with a load-bearing capacity of up to 3-5kg
6. ypical uses: Thickened load-bearing shopping bags, fruit tree cold proof cloth, engineering geotechnical cover layer

Note: The above are the benchmark indicators for mainstream qualified products in the industry. The modified version with added antibacterial, UV resistant and other functional masterbatch will have its corresponding mechanical indicators adjusted according to the formula. When purchasing, the manufacturer can be requested to provide a third-party testing report for verification of the corresponding weight.
