　　聚乙烯（polyethylene ，简称PE）是乙烯经聚合制得的一种热塑性树脂。在工业上，也包括乙烯与少量α-烯烃的共聚物。聚乙烯无臭，无毒，手感似蜡，具有优良的耐低温性能（最低使用温度可达-100~-70°C），化学稳定性好，能 耐大多数酸碱的侵蚀（不耐具有氧化性质的酸）。常温下不溶于一般溶剂，吸水性小，电绝缘性优良。

　　PE (polyethylene) is a thermoplastic resin made by polymerization of ethylene. In industry, it also includes copolymers of ethylene with a small amount of alpha olefins. Polyethylene is odorless, non-toxic, feels waxy, has excellent low-temperature resistance (minimum use temperature up to -100~-70 degrees C), good chemical stability, resistance to most acid and alkali erosion (not oxidation resistant acid). It is insoluble in general solvent at room temperature, has little water absorption and good electrical insulation property.

　　其原名叫聚乙烯，是塑料的一种。聚乙烯无臭，无毒，手感似蜡，具有优良的耐低温性能，化学稳定性好，能耐大多数酸碱的侵蚀，不耐具有氧化性质的酸,常温下不溶于一般溶剂，吸水性小，电绝缘性能优良。

　　Its original name is polyethylene, which is a kind of plastic. Polyethylene is odorless, non-toxic, feels like wax, has excellent low-temperature resistance, good chemical stability, resistance to most acid and alkali erosion, not resistant to oxidation of acid, at room temperature insoluble in general solvents, water absorption is small, electrical insulation performance is excellent.

　　所以，常用于制作塑料包装袋、薄膜、塑料瓶、瓶盖、PE保鲜膜等产品，是制作食品包装最佳选择之一。如果与evoh或尼龙等其他材质复合，还可制作出性能更加优良的塑料包装袋，可具有防潮、防穿刺、高隔绝性能、化学稳定性好等特点。常用于高端食品包装，比如：蛋液包装袋、奶制品包装袋等，可有效保持易变质食品的新鲜度。

　　Therefore, it is commonly used in the manufacture of plastic packaging bags, film, plastic bottle, bottle cap, PE film and other products, is one of the best choice for food packaging. If it is combined with EVOH or nylon and other materials, the plastic packing bag with better performance can be made, which has the characteristics of moisture proof, puncture proof, high isolation performance and good chemical stability. Commonly used in high-end food packaging, such as egg packaging bags, packaging bags and other dairy products, can effectively maintain the freshness of perishable food.
