The POF thermal shrinkable thin film is used as the middle layer of linear low density polyethylene (LLDPE) in the special equipment, as the inner and outer layers of the polypropylene (PP). The inner, middle and outer layers are extruded together by special technology, and the high transparency, high shrinkage and heat sealing performance are good. Heat shrinkable film. The system is designed by the principle of polymer molecular chain stretching orientation. It has all advantages and advantages of polyethylene (PE) and polypropylene (PP), and its excellent performance is far superior to pure polyethylene (PE) film and polypropylene (PP) film. It is widely used in the world at present. Environmentally friendly shrink wrap materials approved by European and US markets. It is in conformity with the FDA and USDA standards of the United States. It is made by environmental protection materials. It is a kind of environmentally friendly packaging material, which can be recycled and reused, especially for the pharmaceutical industry and the food industry.
Product features: after shrinking packaging, the edge corner of the seal is soft; it is non-toxic and does not produce toxic gas in the heat sealing process; it is thin and toughened, the thickness is uniform, the texture is soft, the moisture resistance is better, the cold resistance is excellent, the winter is not hard, no embrittlement, and it is not easy to break in transportation in winter. After shrink packaging, the tightening force will not change, so that the packaging will not be deformed for a long time.
Scope of application:
This kind of shrinkable film can be packaged by automatic or semi-automatic mechanical operation or manual operation, and more reasonable packaging machinery can be used according to the different packaging methods of the product. At present, this product has been widely used in many industries, such as daily necessities, food hygiene and health products, medicine, stationery, cosmetic products, audio and video products, native products, kitchen products, clothing, clothing, clothing, toys, crafts, beverages, fruits, vegetables, frozen food and so on.
