PE heat shrink film is a certified non-toxic material, which can make heat shrink label material with high transparency, good processing performance and good toughness. PE is a non-polar material that has a weak adhesive force with ink and the ink layer easily falls off, so surface treatment must be performed before printing. PE heat shrink membranes are especially suitable for industries such as food, pharmaceuticals and beverages.
The POF heat-shrinkable film has linear low-density polyethylene as an intermediate layer and copolymerized polypropylene as an inner and outer layers. As a heat shrink film material, POF heat shrink film is mainly used for packaging rules and irregularly shaped products. Its non-toxic eco, high transparency, high shrinkage rate, good heat sealing performance, high glossiness, strong toughness, tear prevention, uniform heat shrinkage, suitable for fully automatic high-speed packaging, etc. I have. Fields such as food, canned beverages, dairy products, and pharmaceuticals.
OPS heat shrink film is a new type of close-contact packaging material that meets the requirements of environmental protection. Conforms to hygiene standards. This film can meet the label demand of several novel packaging containers with different outer shapes, producing a visual effect where beauty is devastated. It's quite progressive to keep looking for beautiful shrink labels.
The PVC heat shrink film is made by a tensioning process by the foam tube method. PVC heat shrink film has advantages such as waterproof, fire resistance, electrostatic resistance, easy to mold, high transparency, high gloss, high shrinkage rate, low input, high yield, etc., so it is widely used nowadays. It is a material. However, this material is not good for the environment because it easily generates poisonous gas when burned.
The OPP heat shrink film has a low shrinkage rate and is mainly used to shrink the area of the label, better protects the printed text to improve the abrasion resistance of the ink layer, and has the same properties on the surface. It has a composite base material and is suitable for low shrinkage cylindrical or ring can type containers.
PET heat shrink film is a heat shrink packaging material. An ordinary PET heat-shrinkable film can obtain a heat-shrinkage rate of 30% or less through a special process, but the maximum heat-shrinkage rate of a PET heat-shrinkable film after copolymerization modification reaches 70% or more. It is easy to recover, tasteless, non-toxic and has good mechanical performance, so it is especially suitable for environmental protection features. In developed countries, it has become an ideal replacement for PVC heat-shrinkable membranes. With the rapid development of PET beverage bottles, the application of PET shrink labels is also expanding.
