ana fark arasında PE ısı shrink film ve POF shrink film
1.Farklı tanımlar
POF araçlar ısı-büzülebilir film. POF standlar for multi-layer co-extruded polyolefin heat-shrinkable film. It uses lineer low-density polietilen as the the middle layer (LLDPE) and copolymerized polypropilere (pp) as the iç ve outer layers. It is plastikleştirilmiş ve ekstrüde by the machine, and then processed by special process such as die molding and film bubble inflation.
PE film is a kind of material with good toughness, and it is not easy to be crushed by ordinary plastic shredders. Çünkü the PE film is soft and tough, it is not easy to shred, not to mention the high temperature of the tool at high speed, which will cause LDPE to melt and adhere to the blade. The granülasyon of PE can be direkt put into the feeding port of the extruder in strips, and the PE film is dragged in the barrel by the shear force of the screw to heat, melt, extrude and granül. The first-grade material recovered from PE can still be blown film, used for for-food and farmasötik ambalaj, and is also widely used in the production of Oxford deri ve branda, a parlak gelecek ile.
2. Fiziksel özellikler
PE is kalın ve sert, ile üniforma kalınlık, iyi nem direnç ve yumuşak doku. The tear strength is lower than POF, and the rub resistance is not as good as POF.
3.Uygulama
PE ısı büzülebilir film is widely kullanılan içinde ambalaj of şarap, teneke kutular, mineral su, çeşitli içecekler, kumaş ve diğer ürünler. The product has good flexibility, impact resistance, tear resistance, and is not easy to break Tide, large shrinkage.
POF is a heat-shrinkable film, which is mainly used for packaging regular and irregular shaped products. Uniform shrinkage and suitable for automatic high-speed packaging, etc., widely used in automotive supplies, plastic products, stationery, books, electronics, circuit boards, MP3, VCD, handicrafts, photo frames and other wooden products, toys, insecticides, daily necessities, food, Cosmetics, canned beverages, dairy products, pharmaceuticals, cassettes and video tapes and other products.
