Polypropylene (PP) is a thermoplastic resin produced by polymerization of propylene monomers. According to the different spatial positions of -CH3 in the polypropylene molecule, it can be divided into three configurations: isotropic, atactic and interstitial. Polypropylene woven bags have better strength, rigidity and transparency than polyethylene, and can be modified and added antioxidants to overcome the shortcomings of poor low-temperature impact resistance and easy aging.

Characteristics of woven polypropylene bags

Polypropylene woven bag has many advantages such as high mechanical strength and impact strength, not easy to wear and bend, resistant to boiling water and alkaline, that is, low temperature and high temperature, resistant to organic solvents and acids, not rotten or corrosive, does not change texture when storing petroleum products, color does not change when exposed to ultraviolet light and high temperature, gas is difficult to penetrate, can be used for food packaging, light weight, insulating material, easy to handle or recycle.
