　　The ordinary plastic film in the PE preservative film:

　　PE保鲜膜中的普通塑料膜主要是采用吹塑成型、T型摸法成型溶液最终流涎成I以及压延成型的未经处理的一类薄膜，后期表现出来的包装性能主要取决于树脂品种等。

　　Common plastic film in PE film is mainly by blow molding, molding touch type T into I and finally the solution ptyalism calendering without a film processing, packaging performance mainly depends on the late show resin varieties.

　　PE保鲜膜中的定向拉伸塑薄膜

　　Directional tensile plastic film in PE fresh-keeping film

　　PE保鲜膜中定向拉伸塑薄膜主要就是就是将普通塑料薄膜在其博瑞化至熔点的某一沮度条件之下拉伸到原来长度的几倍，再就是处于张紧状态下，在高于其拉伸沮度或者是低于熔点的温度区间某一沮度保持几秒再进行热处理定型，最后就是急速的冷却至室沮。

　　PE directional tensile plastic film is mainly is the common plastic film in the brilliant of melting point to a temperature under conditions of stretch to several times of the original length, and is under tension at higher than its tensile temperature is lower than the melting temperature range or a temperature for a few seconds then the heat treating, finally is rapidly cooled to room temperature.

　　PE保鲜膜中的热收缩薄膜

　　Heat shrinkable film in PE fresh-keeping film

　　大家一般会将未经热处理定型的定向拉伸薄膜命名为热收薄膜.而大家知道拉伸薄膜聚合物大分子的定向分布状态都是不位定的。处于高拉伸温度和低熔点温度的背景下.分子热运动便大分子从定向分布状态又恢里到无规则团状态.使拉伸薄膜沿拉伸方向收绪还原，这种热收缩怜能被应用于包装食品，对包装品具有很好的保护性，商品展示性和经济实用性.

　　Generally speaking, the directionally stretched film without heat treatment is named as heat absorbing film. However, we all know that the directional distribution state of polymer film in stretched film is not definite. In the high temperature tensile and low melting point temperature. Under the background of thermal motion of molecules will be molecules from the directional distribution state again in the group to irregular state. The tensile film stretched along the direction of closing thread reduction, the thermal contraction flow can be used in food packaging, has the very good protection of packaged goods, goods the show and economic practicality.

　　PE保鲜膜中的弹性(拉伸)薄膜

　　Elastic (tensile) film in PE fresh-keeping film

　　PE保鲜膜中的弹性薄续材质上属于一种拥有比较特殊性能的薄膜，廷伸率比较大再就是比较强大的强度.后期可以表现出来很好的拉伸弹性和弹性张力.拉伸薄膜性健提标

　　The elastic thin continuous material of PE fresh-keeping film is a kind of thin film with special properties. The larger elongation rate is stronger strength. Later, it can show good tensile elasticity and elastic tension. Stretch film is healthy.
