PET film modification, come in to understand the source: protective film factory direct sales Release time: 2019-03-13 Click: 3761 Ordinary polyester is a crystalline polymer, ordinary PET film can only get less than 30% of heat through special processing Shrinkage. 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 thermal shrinkage rate of the PET film modified by copolymerization can be as high as 70% or more.
