PET Shrink Film Labels Enhancing Brand Visibility

Ordinary polyesters are crystalline polymers, and special processing of ordinary PET films can only achieve a heat shrink rate of less than 30%. To obtain PET films with higher heat shrinkage rates, modification is also necessary. This means that to prepare high heat shrink PET films, copolymer modification of ordinary polyesters, i.e., polyethylene terephthalate, is required. The maximum heat shrinkage rate PET films after copolymer modification can be as high as over 70%. Characteristics of heat shrinkable polyester films: They are stable at room temperature shrink when heated (above the glass transition temperature), and exhibit more than 70% heat shrinkage in one direction. The advantages of heat shrinkable polyester packaging are: ① It is transparent and adheres closely to the product, showcasing the product's image. ② It tightly bundles the packaged items, providing good-scattering properties. ③ It is waterproof, moisture-proof, and mildew-resistant. ④ It has no restorative pr…
