PE heat shrinkable film is a recognized non-toxic material

PE heat shrinkable film is a recognized non-toxic material, which can be made into heat shrinkable label material with high transparency, good processing performance and good toughness. Because PE is a non-polar material, it has weak adhesion to the ink and the ink layer is easy to fall off, so surface treatment must be performed before printing. PE heat shrinkable film is especially suitable for food, medicine, beverage and other industries. PVC heat shrinkable film is generally made by bubble tube stretching process. Because PVC heat shrinkable film has the advantages of waterproof, fire-resistant, antistatic, easy to form, high transparency, high gloss, high shrinkage rate (up to 70%), and features such as low investment and high output, it is widely used today A synthetic material. However, the material easily produces poisonous gas when burned, which is not conducive to environmental protection. The shrinkage rate of OPP heat shrinkable film is low, and it is mainly used in the field of shrinking and wrapping labels. In order to improve the friction resistance of the ink layer and better protect the printed graphics, a layer of substrate of the same nature is also laminated on the surface. Suitable for cylindrical or ring tank containers with low shrinkage. POF heat shrinkable film uses linear low-density polyethylene as the middle layer and co-polypropylene as the inner and outer layers. As a kind of heat shrinkable film material, POF heat shrinkable film is mainly used for packaging products with regular and irregular shapes. Because of its non-toxic and environmental protection, high transparency, high shrinkage, good heat sealing performance, high gloss, strong toughness, and resistance It has the characteristics of uniform tearing, uniform heat shrinkage and suitable for fully automatic high-speed packaging. It is a replacement product of traditional PVC heat shrinkable film and is widely used in electronics, daily chemicals, food, canned beverages, dairy products, medicine and other fields. OPS heat shrinkable film is a new type of skin packaging material that meets environmental protection requirements. It has high strength, high rigidity, good gloss, high shrinkage (up to 65%), non-toxic, odorless, and grease resistance, and meets food hygiene standards. This kind of film can meet the label requirements of some novel packaging containers with different shapes and produce a beautiful visual effect. For the continuous pursuit of exquisite shrink labels, it is a complete improvement. PET heat shrinkable film is a kind of heat shrinkable packaging material. Ordinary PET heat shrinkable film can only get a heat shrinkage rate of less than 30% after special processing, but the highest heat shrinkage rate of PET heat shrinkable film modified by copolymerization can reach more than 70%. Because of its easy recyclability, odorless, non-toxic, good mechanical properties, and especially in line with the characteristics of 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.
