POF Film Material

POF film material is made of, POF stands for multi-layer co-extruded polyolefin heat shrinkable film, which uses linear low-density polyethylene as the middle layer (LLDPE), and copolymerized polypropylene (pp) as the inner and outer layers, through five extruders It is plasticized and extruded, and then processed by special processes such as die forming and film bubble inflation. The main raw materials of the five-layer co-extruded heat-shrinkable packaging film include LLDPE (linear low-density polyethylene), TPP (terpolymerized polypropylene), PPC (binary copolymerized polypropylene) and necessary functional additives such as slip agent, Antiblocking agent, antistatic agent, etc. POF heat-shrinkable packaging film has a wide range of uses, a broad market, and has the advantages of environmental protection and non-toxicity. Therefore, it has been widely valued by developed countries in the world. The hygienic performance of this product meets the standards of the US FDA and USDA. It can be used for packaging food. POF film materials have basically It replaces PVC heat shrinkable packaging film and becomes the mainstream product in heat shrinkable packaging materials.

Advantages of POF film material products:

1. High transparency and good gloss, which can clearly display the appearance of the product, improve sensory awareness, and reflect high-grade. 

2. The shrinkage rate is large, up to 75%, and the flexibility is good. It can pack any shape of goods, and the shrinkage force of the three-layer co-extrusion film treated by special technology is controllable, which meets the needs of different commodity packaging for shrinkage force. Require. 

3. Good sealing performance and high strength, suitable for manual, semi-automatic and high-speed automatic packaging.
