PE stretch film development prospects

PE stretch film is developed from single layer to second layer and third layer. Now PE casting film is mainly produced by casting method; PE stretching film is widely used in wine, cans, mineral water and various beverages. The whole package of products such as cloth and cloth, the product has good flexibility, strong impact resistance, tear resistance, not easy to break, not afraid of tide, and large shrinkage.


PE stretch film is a kind of transparent thermoplastic. PE is commonly used in three categories, namely: LDPE, HDPE, LLDPE. The monomers of the three kinds of polyethylene are the same, but the process conditions used when synthesizing these polyethylenes Different, so three different types of polyethylene are produced, and the performance of the three materials is quite different.


Early PE stretch film has more blown film. This is because the casting line has the advantages of uniform thickness and high transparency, which can be applied to the requirement of high-rate pre-stretching. Since single-layer casting can not achieve single-sided adhesion, application The field is limited. The single and double-layer casting has no three-layer casting in the data selection, and the formula interest is also high. Therefore, it is better to have a three-layer co-extruded structure.


PE stretch film is a very tough material. It is not easy to be crushed by ordinary plastic pulverizer. Because PE film is soft and tough, it is not easy to be shredded. Moreover, the high temperature of the tool at high speed will cause LDPE to melt and adhere to the blade. PE granulation can be directly put into the extruder feeding port, and the PE film is dragged into the barrel by the shearing force of the screw to heat the melt extrusion granulation. The first material recovered by PE can still be blown film for Non-food and yao packaging, also widely used in the production of Oxford leather and tarpaulins, the future is bright.
