Automotive Shrink Film is a recognized non-toxic material, which can be made into a heat-shrinkable label material with high transparency, good processing performance and good toughness. Since PE is a non-polar material, the adhesion to the ink is weak, and the ink layer is easily peeled off, so surface treatment must be performed before printing. PE heat shrinkable film is especially suitable for food, medicine, beverage and other industries.
Shrinkable film is generally produced by a bubble tube stretching process. Because Resistance to Oil PVC Shrink Film has the advantages of waterproof, fireproof, antistatic, easy to form, high transparency, high gloss, high shrinkage (up to 70%), low input and high output, it is widely used today. A synthetic material. However, this material is prone to toxic gas when burned, which is not conducive to environmental protection.
Shrinkable film has a low shrinkage rate and is mainly used in the field of shrinking and wrapping labels. In order to improve the rubbing resistance of the ink layer and better protect the printed image, it is also necessary to laminate a substrate of the same nature on the surface. Suitable for cylindrical or ring-shaped containers with low shrinkage.
Shrinkable film is a heat shrinkable packaging material. The ordinary PET heat shrinkable film can only obtain a heat shrinkage rate of less than 30% after special treatment, but the maximum heat shrinkage rate of the PET heat shrinkable film after copolymerization modification can reach more than 70%. Because it is easy to recycle, tasteless, non-toxic, and has good mechanical properties, it is particularly suitable for environmental protection. It has become an ideal product to replace PVC heat shrinkable film in developed countries. With the rapid development of PET beverage bottles, the application of PET shrink labels is also expanding.
