PE薄膜是一种韧性很好的材料，不容易用普通的塑料粉碎机粉碎。由于PE膜软而韧，也不易切碎，更何况高速下刀具温度高，会使LDPE熔化粘附在刀刃上。PE的造粒，可直接成条放入挤出机加料口，靠螺杆的剪切力把PE膜拖进机筒加热熔融挤出造粒。PE回收的一级料，仍旧可吹膜，用于非食品和药品包装，还广泛用于牛津革和防水布的生产上，前途光明。
PE film is a material with good toughness. It is not easy to crush with ordinary plastic crusher. Because the PE film is soft and tough, it is not easy to cut, let alone the high temperature of the cutting tool at high speed, which will make LDPE melt and adhere to the cutting edge. The pelletizing of PE can be directly put into the feeding port of the extruder, and the PE film is pulled into the barrel of the extruder by the shear force of the screw to be heated and melted to extrude the pelletizing. PE recycled primary material can still be blown film, used in non-food and pharmaceutical packaging, but also widely used in the production of Oxford leather and waterproof cloth, with bright future.
PE热收缩膜广泛适用于酒类、易拉罐类、矿泉水类、各种饮料类、布匹等产品的整件集合包装，该产品柔韧性好,抗撞击、抗撕裂性强，不易破损、不怕潮、收缩率大。
PE heat shrinkable film is widely used in the whole package of wine, cans, mineral water, beverages, cloth and other products. The product has good flexibility, impact resistance, tear resistance, not easy to break, not afraid of moisture, shrinkage rate.
PVC收缩膜
PVC contractile membrane
PVC聚氯乙烯，外加成分以增强其耐热性，韧性，延展性等。这种表面膜的最上层是漆，中间的主要成分是聚氯乙烯，最下层是背涂粘合剂。它是当今世界上深受喜爱、颇为流行并且也被广泛应用的一种合成材料。在可以生产三维表面膜的材料中，PVC是最适合的材料。
PVC polyvinyl chloride is added to enhance its heat resistance, toughness, ductility and so on. The top layer of the surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is the back coating adhesive. It is a kind of synthetic material which is very popular, widely used and widely used in the world today. PVC is the most suitable material for producing three dimensional surface film.
由于PVC独特的性能(防雨，耐火，抗静电，易成型)和PVC低投入高产量的特点，被广泛地应用于建材行业和包装行业，因此，PVC薄膜具有透明度高、光泽度好、收缩率高等特点。
Because of its unique properties (rain proof, fire resistance, antistatic, easy to form) and low input and high output of PVC, PVC film is widely used in building materials industry and packaging industry. Therefore, PVC film has the characteristics of high transparency, good gloss and high shrinkage.
POF 收缩膜
POF shrink film
POF就是热收缩膜的意思，POF全称多层共挤聚烯烃热收缩膜，它是将线性低密度聚乙烯作为中间层（LLDPE），共聚丙烯（pp）作为内、外层，通过三台挤出机塑化挤出，再经模头成型、膜泡吹胀等特殊工艺加工而成的。
POF is the meaning of heat shrinkable film. POF is called multi-layer co-extrusion polyolefin heat shrinkable film. It is made of linear low density polyethylene (LLDPE) as the intermediate layer, and polypropylene (pp) as the inner and outer layer through three extruders, and then processed by die forming, bubble blowing and other special processes.
POF是一种热收缩膜，主要用于包装规则和不规则形状的产品，由于其无毒环保、高透明度、高收缩率、良好的热封性能，高光泽度、强韧性、抗撕裂、热收缩均匀及适合全自动高速包装等特点,是传统PVC热收缩膜的换代产品，广泛应用于汽车用品，塑料制品，文具，书本，电子，线路板，MP3，VCD，工艺品，相框等木制品，玩具，杀虫剂，日用品，食品，化妆品，罐装饮料，乳制品，医药，盒带及录像带等产品。
POF is a kind of heat shrinkable film, which is mainly used for packaging regular and irregular shape products. Because of its non-toxic, environmental protection, high transparency, high shrinkage, good heat sealing performance, high gloss, toughness, tear resistance, uniform heat shrinkage and suitable for full automatic high-speed packaging, POF is a replacement product of traditional PVC heat shrinkable film. Widely used in automotive products, plastic products, stationery, books, electronics, circuit boards, MP3, VCD, handicraft, photo frames and other wood products, toys, pesticides, daily necessities, food, cosmetics, canned drinks, dairy products, medicine, cassettes and videos.
