The POF shrink film is also known as thermal shrink-wrap product. The main feature is to heat the product with heat-shrinkable film wrapping to make the film shrink and wrap the product tightly. Wrapped with POF barrels of membrane material on the outside of the product or package, after heating, shrink wrapped to make product or package, abundant show appearance of the item, the progress of product exhibit, increase the aesthetic value of.

POF shrink film packaging machine adopts shrink film package, outside the product or package after heat shrinkable film wrapped tight products or packaging, fully display items appearance, improve the product exhibit, increase the aesthetic value of. After the goods at the same time, the packing sealing, moistureproof, prevent pollution, and protect the goods from external shocks, has some buffer, especially when packing fragile, can prevent vessel flying when crushed.

The project adopts magnetic field enhanced plasma chemical vapor deposition method, combined with roller technology, and deposited inorganic nanometer high barrier layer on the surface of crosslinking membrane. The research and development of inorganic nanometer high barrier packaging film materials are mainly used in food and drug packaging materials which have the ability to block.
