Classification of plastic bags
Degradable and non-degradable. Both PE bags and nylon bags are plastic bags with different materials. PE bags are divided into high density and low density. High-density ones are tougher, have higher transparency, feel stiffer, and are relatively expensive. Generally, the plastic bags given by supermarkets are high-density PE bags. The low-density PE bag is the most common kind of bag that is very soft to the touch in the general market, with inferior quality, poor transparency and low price. Nylon bags refer to plastic bags made of various polyamides, which vary depending on the specific amide material. But overall, it looks good in texture, thick and silky smooth to the touch. Generally used for high-end clothing, jewelry and other commodities, the price is relatively high. In China, it is basically non-degradable, and the degraded one has not been used on a large scale, polylactic acid PLA.
