Nowadays, environmental pollution control is imminent, to protect the sustainable development of the economy and society people have taken a variety of behaviors, and PFT heat shrink film is particularly in line with the characteristics of environmental protection because it is easy to recycle, non-toxic, tasteless, good mechanical properties. So, what is PET heat shrinkable film?

PET heat shrink film is a new type of heat shrink packaging material. Ordinary polyester is a crystalline polymer, ordinary PET film can only get a heat shrinkage rate of less than 30% after a special process. If you want to get higher heat shrinkage polyester film, it must also be modified. That is to say, to prepare high heat shrinkage polyester film, it is necessary to copolymerization modification of ordinary polyester that is polyethylene terephthalate. The highest heat shrinkage rate of the copolymerization-modified PET film can be as high as 70% or more.

Characteristics of PET heat shrinkable polyester film

It is stable at room temperature, shrinks when heated (above the glass transition temperature), and is more than 70% heat shrinkage occurs in one direction.

The advantages of PET heat shrinkable polyester film packaging are.

1, stick to the body transparent, reflecting the image of the goods.
2, tight bundle packaging, good anti-scattering.
3, rain, moisture, mold.
