What material is the woven bag made?
Release time:
2023-08-14
Woven bag is a commonly used plastic bag, mainly made of polyethylene or polypropylene. Stretch into flat filaments and then weave them. Preparation. Bags, due to the strength of polypropylene. Rigidity and transparency are better than polyethylene, so it is used more, and the role of woven bags is also more extensive. They are commonly used as packaging bags and can be used for packaging industrial and agricultural products. Food and so on, among other things, tourism. Engineering materials field. Woven bags are also used for flood relief.

Woven bags, also known as snakeskin bags, are a kind of plastic bags, mainly used for packaging, so what is the material of plastic woven bags:
1. Polyethylene
Also known as PE plastic is a thermoplastic resin made of ethylene polymerization. Polyethylene plastic woven bags have good performance, but polyethylene is sensitive to environmental stress, poor heat resistance and aging, and is less used in China.
2. Polypropylene
Generally speaking, most woven bags in China are made of polypropylene. Polypropylene is a thermoplastic resin made of propylene polymer with isotactic material. The strength of the three configurations of atactic and syndiotactic. The rigidity and transparency are better than polyethylene, and the shortcomings of poor low temperature impact resistance and easy aging can be overcome by modification and addition of antioxidants.
In plastic products, plastic weaving is a flexible material with high breaking strength, which is related to its molecular structure, crystallinity, drafting direction and additive type. If the plastic braid is measured in specific strength (strength/specific gravity), it is higher or close to the metal material.
At room temperature, the plastic woven cloth is actually completely free from moisture erosion, and the water absorption rate is less than 0 within 24 hours. 01%, the permeability of water is also very low. At low temperatures, it becomes brittle. Plastic braid will not mold.
