行政法规是什么制定的
PE is the most widely ud plastic in industry and life. It is usually divided into two kinds: high density polyethylene (HDPE) and low density polyethylene (LDPE).
sudden
PE is excellent for acid and alkaline resistance. HDPE has higher melting point, higher hardness and more corrosion resistant liquid than LDPE.
At prent, the plastic bags and translucent plastic bottles are almost all made of PE, such as detergent, shampoo, bath milk, edible oil And so on, most of them are filled with HDPE bottles. LDPE is ubiquitous in modern life, but not containers made of it, but plastic bags that you can e everywhere. Most plastic bags and plastic films are made of LDPE.

PS foam (commonly known as styrofoam) is the u of foaming agent in the preparation process of 20 times to 100 times the foam ud for packaging, houhold appliances or information items of the buffer packaging material or ice cream box, with heat insulation effect of fish tank, commonly known as EPS (Expanded polystyrene); at the same time also made for disposable tableware, this is usually made of styrofoam plate, called PSP (Expanded polystyrene Paper), and then forming a variety of containers, as well as food grade EPS injection molded polystyrene, such as coffee cup, cup is burn.
