　　大家都知道，塑料袋主要成分是聚乙烯。那么聚乙烯有哪些分类呢？

Everyone knows that the main component of plastic bags is polyethylene. So what are the classifications of polyethylene?

　　聚乙烯，简称PE，是乙烯经聚合制得的一种热塑性树脂，聚乙烯无臭，，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，常温下不溶于一般溶剂，吸水性小，电绝缘性优良，具有的作用有：

Polyethylene, abbreviated as PE, is a thermoplastic resin produced by polymerization of ethylene. Polyethylene is odorless, non-toxic, and has a wax like feel. It has excellent low-temperature resistance, good chemical stability, and can withstand most acids and alkalis. It is insoluble in general solvents at room temperature, has low water absorption, and excellent electrical insulation properties. Its functions include:

　　1.高压聚乙烯： 一半以上用于薄膜制品，其次是管材、注射成型制品、电线包裹层等；

1. High pressure polyethylene: More than half of it is used for thin film products, followed by pipes, injection molded products, wire wrapping layers, etc;

　　2.中低、压聚乙烯： 以注射成型制品及中空制品为主；

2. Low to medium pressure polyethylene: mainly used for injection molded products and hollow products;

　　3.超高压聚乙烯： 由于超高分子聚乙烯优异的综合性能，可作为工程塑料使用。

3. Ultra high pressure polyethylene: Due to its excellent comprehensive properties, ultra-high molecular weight polyethylene can be used as an engineering plastic.
