Woven bag is a commonly used plastic bag, mainly made of polyethylene or polypropylene, stretched into flat silk, and then woven, woven and bagged. Because the strength, rigidity and transparency of polypropylene are better than polyethylene, so it is used more, the role of woven bags is also more extensive. They are commonly used as packaging bags and can be used to pack industrial and agricultural products. Food, etc. Besides, tourism. Woven bags are also used in flood fighting and disaster relief.
Woven bag, also known as snakeskin bag, is a kind of plastic bag, mainly used for packaging, then what is the material of plastic woven bag? Generally speaking, woven bags have two raw materials:
1. Polyethylene
Also known as PE plastic is a thermoplastic resin made of ethylene polymerization. Polyethylene plastic woven bag has good performance, but polyethylene is sensitive to environmental stress, poor heat resistance and aging, so it is less used in China.
2. Polypropylene
Generally speaking, most woven bags in China are made of polypropylene. Polypropylene (PP) is a thermoplastic resin made from an acrylic polymer with isotropic substances. Random and intergauge three configurations, its strength. The rigidity and transparency are better than polyethylene, and can be modified and added antioxidants to overcome the low temperature impact resistance, easy aging shortcomings.
In plastic products, plastic braid is a kind of flexible material with high breaking strength, which is related to its molecular structure, crystallinity, drafting direction and additive type. If a plastic braid is measured in specific strength (strength/specific gravity), it is higher than or close to a metal material.
At room temperature, plastic braided cloth is actually completely resistant to water erosion, and the water absorption rate is less than 0 within 24 hours. 01%. Water permeability is also very low. At low temperatures, it becomes crunchy. Plastic braids don’t get moldy.
