In addition, it can reduce the possibility of the product being dismantled and stolen.

Ordinary polyester is a crystalline polymer, and ordinary PET Shrink Wrap can only get a thermal shrinkage rate of less than 30% after special process treatment. In order to obtain a higher thermal shrinkage polyester film, it must also be modified. In other words, in order to prepare polyester film with high thermal shrinkage, common polyester, namely polyethylene terephthalate, needs to be copolymerized. The highest thermal shrinkage rate of the copolymerized PET film can be as high as 70%.

The characteristics of PET Shrink Wrap: it is stable at room temperature, shrinks when heated (above the glass transition temperature), and more than 70% of the thermal shrinkage occurs in one direction. The advantages of shrinkable polyester film packaging are: 1.transparent body, reflecting the image of the product. 2.Tight packaging, good dispersion resistance. 3.Rain, moisture, mildew proof. 4.no resilience, there is a certain anti-counterfeiting function. Shrinkable polyester film is often used in convenient food and beverage markets, electronic appliances, metal products, especially shrink labels is its most important application field. Because with the rapid development of PET beverage bottles, such as cola, Sprite, all kinds of juice and other beverage bottles need PET heat shrinkable film with it to make heat seal labels, they belong to polyester, is environmentally friendly materials, easy to recycle and reuse.

In addition to being used as shrink labels, PET Shrink Wrap began to be used on the outer packaging of daily goods.
