Industrially, it also includes copolymers of ethylene and a small amount of α-olefins; PE bags are a kind of transparent plastic bags, which can be used for packaging clothing, luggage, electronic products, etc. Since many plastic products are not disposable, they still have recycling value after being recycled. Moreover, after being recycled, washed, and pulverized, they can be remelted and then injection-molded or extruded into new plastic products, and a hot melt machine is needed to complete the melting.
