This unit uses PVC (polyvinyl chloride) as the main raw material and several different grades of resin to

 produce single-sided or double-sided stretch wrap film with self-adhesive properties through extrusion. 

The film has good shrinkage memory and self-adhesive property, which can make the goods tightly 

wrapped into a whole, prevent flashing down and dust pollution during transportation, and also has 

excellent transparency and extensibility, which can make the packing goods beautiful and economical. 

It can be widely used for bulk cargo packaging on pallets, and is a better alternative to heat shrink 

packaging film in transportation.
