What is cross-linked film?

Cross-linked film is a kind of shrink film, which is suitable for packaging products with certain special needs, such as electronic products, banknotes, lottery tickets and other special products. The shelf effect of cross-linked film is also very good. 

Cross-linked film is made of ethylene with low linear density as the middle layer and polypropylene as the inner and outer layers, which is plasticized and extruded by three extruders, and then processed by die head molding, film bubble blowing and other processes. Heat shrink packaging film is a multi-layer environmentally friendly heat shrink packaging material produced by co-extrusion blow molding process with PE and PP as the main raw materials.

The main uses of cross-linked film are reflected in glass protective film, electronic product protective film, car protective film, household protective film, food preservative film, etc. At present, electronic products are more commonly used, such as mobile phones, computers, IPAD and other products. There are many similar protective films in life, which are widely used. Cross-linked film has a very good shrinkage rate, and the sealing is firm and durable, and the shrinkage temperature range is wider.

Cross-linked film is an environmentally friendly material, belonging to odorless product packaging bags, with active active genes. It can react with double bonds, hydroxyl groups and other genes under the action of catalysts, and is the basic raw material for products such as foam levelers, defoamers, and water-soluble silicone oils. It has good waterproof properties and can be used as a waterproofing agent for glass, paper, metal, ceramics, cement and other items.
