POF heat shrinkable film is a kind of packaging film with transparent gloss and close to the appearance of the product. Its energy saving, high shrinkage, transparent gloss and strong tear resistance subvert the limitations of traditional packaging film. The market is popular and is loved by consumers.

 

 

Pof shrink film is mainly processed by plasticizing extrusion process. Shrink film can be used to package regular and irregular shape products, and its transparency is better, which can make people understand products more clearly and increase people. The level of understanding of the product, thereby promoting people to buy.

 

The POF shrink film is designed by using the high-strength molecular chain stretching orientation principle and formed by quenching and setting. The physical principle is: when the ionomer is in a high elastic state, it is stretched and oriented, and then the polymer is quenched to below the glass transition temperature, the molecular orientation is frozen, and when the article is heated during packaging As the molecular motion produces stress relaxation, the molecule returns to its original state and produces shrinkage. With its superior winding force and retractability, the POF shrink film bundles the product into a unit compactly and fixedly, making the scattered small parts a whole, even without any looseness and separation in the unfavorable environment. There are no sharp edges and stickiness to avoid damage.
