PET film modification-film supplier

Ordinary polyester is a crystalline polymer, and ordinary PET film can only get a heat shrinkage rate of less than 30% after special processing. To obtain a polyester film with a higher heat shrinkage rate, it must also be modified. That is to say, in order to prepare a polyester film with a high heat shrinkage rate, it is necessary to copolymerize and modify ordinary polyester, ie, polyethylene terephthalate. The highest heat shrinkage rate of the PET film modified by copolymerization can be as high as 70% or more.
