１、收缩率高２、光泽度透明度高３、韧性好，不易老化４、密度低，能降低包装成本５、焊接性能好，不易开口６、抗撕裂强度大７、低温时柔软不易破裂８、适用范围广此种收缩膜可以采用自动、半自动机械操作或人工操作进行包装，还可根据产品包装方式的不同使用更合理的包装机械。目前此产品已在许多行业中得到广泛应用，如生活日用品、食品卫生保健品、医药、文教用品、化妆用品、音像制品、土特产品、厨房用品、服装用品、服装纺织品、玩具、工艺品、饮料、水果、蔬菜、冷冻食品等。 POF与PE、PVC收缩膜物理性能优劣比较 POF（环保）热收缩膜 PE收缩膜 PVC收缩膜一、成本 比重0。92，厚度最薄0。012mm，实际单位成本较低。 比重0。92，厚度最薄0。03以上，实际单位成本较高。 比重1。4，厚度最薄0。02mm，实际单位成本较高。

1, the contraction rate is high, high transparency, gloss 2 3 good toughness, not easy to aging, 4 low density, can reduce the packaging cost 5, welding performance is good, not easy to open 6, tear strength 7, low temperature soft and not easy to break 8, applicable to a wide range of the shrink film can be used to automatic, semi self dynamic mechanical operation or manual packaging, packaging machinery can be used according to different product packaging methods more reasonable. At present, this product has been widely used in many industries, such as daily necessities, food and health care products, medicine, stationery, cosmetics, audio-visual products, native products, kitchen supplies, clothing supplies, clothing textiles, toys, crafts, beverages, fruits, vegetables, frozen food etc.. The physical properties of POF and PE and PVC shrink films are compared to POF (environmental) POF shrinkable film PE shrinkage film PVC shrinkage film 1, the cost of the proportion of 0. 92, the thickness is the thinnest 0. 012mm, the actual unit cost is low. The proportion is 0. 92, the thickness is the thinnest 0. More than 03, the actual unit cost is higher. The proportion is 1. 4, the thickness is the thinnest 0. 02mm, the actual unit cost is higher.
