POF /PVC/POFShrink filmMulti-layer co-extruded polypropylene shrinkable film (POF), was dedicated by the device out of shape cooling, the second stretch Inflation and processes made with a high degree of transparency, combined heat and contraction of the film . Is the world's developed countries to use and popular in the international community to promote a wide range of environment-friendly packaging materials shrinking. Speed will be replaced by thermal PVC heat shrinkable film as a major packaging material. POF shrinking the U.S. FDA and USDA standards, is a environmentally friendly packaging materials, recycling can be. In many industries have been widely used, such as the daily necessities of life, food, health care products, medicine, culture, education supplies, cosmetic products, audio-visual products, handicrafts, beverage and other fields. Characteristics: 1, the high rate of contraction 2, high-gloss transparency 3, toughness, aging is not easy 4, low-energy-density packaging to reduce costs 5, welding performance is good, not easy to speak 6, tear strength 7, when the low temperature is not easy soft breakdown 8, the application of broad
