The cosmetic bottle is easy to carry, not afraid of falling, has the characteristics of acid and alkali resistance, convenient production, and is also conducive to recycling. There are many ways to manufacture polyethylene, one of which is very common, which is to polymerize ethylene at a high temperature of 200 to 300 °C and a pressure of 1000 to 2000 atmospheres. In polyethylene, no other substances are doped. The polyethylene thus obtained has low density, soft texture, and high stability to sunlight, air, moisture and chemical reagents, so there is no need to add stabilizers and plasticizers, and stabilizers and plasticizers are mostly Poisonous or highly toxic.
