Find a huge selection of PET Heat Shrink Wrap from China at Xiamen Guanhua. We will provide good service and good price. PET Heat Shrink Wrap is a new kind of shrinkable packaging material. Because it is easy to recycle, non-toxic, tasteless, good mechanical properties, especially in line with environmental protection and other characteristics, in developed countries polyester (PET) has become an ideal substitute for PVC heat shrinkable film.
However, ordinary polyester is a crystalline polymer, and ordinary PET films can only get a thermal shrinkage rate of less than 30% after special processing. 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 Heat 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.
1. The body is transparent, reflecting the image of the product.
2. Tight packing material, good dispersion resistance.
3. Rain, moisture and mildew proof.
4. No recovery, there is a certain anti-counterfeiting function.
PET Heat Shrink Wrap 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.
