英语翻译
高分子材料如橡胶,塑料或纤维,在遇外界一定环境温度时,均有不同程度的尺寸收缩变化.实际产品,大部分要求热稳定性好,尺寸变化率小,但也有部分产品要求在受热情况下有较大的收缩性.高分子材料遇热收缩的性能,与金属材料遇热膨胀的性能相反.利用这一点,将高分子材料制成橡胶热收缩护套管,塑料薄膜热收缩产品,或纤维及纤维编织热收缩产品,应用于各种包装场合.Macromolecule materials such as rubber,plastic or fibre,there is different degree contract change of size of these materials when they meet a certain temperature of circumstance.The actual products,almost require good stability of hot and low rate of the size change.
塑料热收缩薄膜以其透明,品种多,原料来源丰富,制造容易和使用方便,近年来被迅速地应用推广.表1列出主要塑料热收缩膜的性能和应用.除表1品种外,PS,PA,PET,PVCD,EVA等也可以制成热收缩薄膜.热收缩薄膜要求在常温稳定,加热时收缩.热收缩薄膜包装的特点是：①贴体透明,体现商品形象.②紧固集约,防散性好.③包装体积小,减少贮运费用.④防雨,防潮,防霉变.⑤清洁卫生性好.⑥无复原性有一定的防伪,防盗功能.⑦薄膜规格多选择面广.⑧可以回收造粒再利用,对环境不造成二次污染
请帮忙完成上面的翻译

High polymer material like rubber,Plastic or textile fiber,When meets the outside certain ambient temperature,Has the varying degree size contraction change.Actual product,The majority of request thermostability is good,The size rate of change is small,But also has the part of product request to have the big contractility in the being heated situation.The high polymer material meets the hot contraction the performance,Meets the heat expansion with the metal material the performance to be opposite.Using this point,Makes the rubber hot contraction protective covering tube the high polymer material,Plastic film hot contraction product,Or textile fiber and fibrage hot contraction product,Applies in each kind of packing situation.大分子材料例如橡胶,塑料或纤维,当他们遇见某一温度情况时,有这些材料的大小的另外程度合同变动.实际产品,几乎要求好稳定热和低率大小变动.
Plastic hot contraction thin film by its transparent,The variety are many,Raw material origin is rich,Makes easy and the easy to operate,In recent years rapidly is applied the promotion.Table 1 lists the main plastic hot contraction membrane performance and the application.Besides Table 1 variety,PS,PA,PET,PVCD,EVA and so on also may make the hot contraction thin film.The hot contraction thin film request is stable in the normal temperature,When heating contracts.The hot contraction film wrapper characteristic is:①Pastes the body to be transparent,Manifests the commodity image.②The fastening is intensive,Guards against the divergence to be good.③The packing volume is small,Reduced storage and transportation expense.④Rainproof,Moisture-proof,The mold proofing changes.⑤The clean wholesomeness is good.⑥Has certain forgery-proof without the nerve,Security function.⑦The thin film specification multi-choice surface is broad.⑧May recycle makes the grain to use again,does not cause two pollution to the environment
