The chemical molecular structure of polyethylene is very stable and very difficult to degrade, so it takes 300 years for the plastic bags to decompose; while the chemical structure of polypropylene is not solid, and the molecular chain is easy to break, so it can be effectively degraded, and enter the next environmental cycle in the non-toxic form, a non-woven shopping bag can decompose completely in 90 days. Moreover, the non-woven shopping bag can be reused for more than 10 times, and the environmental pollution degree of discarded shopping bag is only 10% of that of plastic bag.
