~Our factory specializes in the production of PVC.PE.POF heat shrinkable film, which can be made into shrinkage bags, single rolls, folding rolls, arcs, barrels and so on. PE heat shrinkable film is widely used in wine, cans, mineral water, beverages, cloth and other products of the whole assembly packaging, the product has good flexibility, impact resistance, tear resistance, not easy to damage, not afraid of moisture, shrinkage rate is large; The film has the characteristics of high transparency, good gloss and high shrinkage. POF has the characteristics of high gloss, good toughness, high tear strength, uniform thermal shrinkage and suitable for automatic high-speed packaging. It is a replacement product of traditional PVC thermal shrinkage film. POF is the meaning of thermal shrinkage film. POF is called multi-layer co-extrusion polyolefin thermal shrinkage film. It is made of linear low density polyethylene (LLDPE) as the intermediate layer, and polypropylene (pp) as the inner and outer layer through three extruders, and then processed by die forming, bubble blowing and other special processes.

The POF film with superior physical properties can completely replace 25-30 micron PVC film with 25 micron PVC film. The POF, PE and PVC properties of 35-50 micron PVC film can completely replace 35-50 micron PVC film with low density of PVC film. Its thickness is 0.92g/cm3, its thickness is thin, its cost is low (density is 0.93g/cm3), its thickness is large, its cost is high (density is 1.4g/cm3), its thickness is large, its cost is high, its physical properties are thin and tough, its thickness is uniform, its quality is smooth, its transparency is good, its luster is high, its thickness is different, its texture is rough and hard, its transparency is poor, its luster is low, its thickness is brittle, its thickness is uneven, its texture is rough and hard, and transparent. Commodity value 1, low temperature resistance, no hardening and brittleness at - 400C, low temperature resistance, not easy to aging. 2. Good heat-sealing performance, high transparency and luster, soft feel, can improve product packaging grade 1. Low temperature resistance, cold in winter will harden but not easy to embrittle, but to increase the thickness is not easy to crack. 2. Poor transparency, rough surface, slightly worse visual effect than POF after packaging 1. Poor cold resistance, brittle hardening in cold or winter, easy to crack. 2. Transparency and glossiness are generally safe. The four corners are soft after contraction, and will not cut the skin. The four corners after contraction and packaging are hard and have poor hand feeling, but they are not easy to cause damage. Shrinkage packaging is hard and sharp, so it is easy to scratch hands. Environmental protection is non-toxic, degradable, and does not produce toxic gases during heat seal processing, environmental protection is non-toxic, does not produce toxic gases during heat seal processing, and produces odor and toxic gases during heat seal processing. Specification: 0.15mm-0.3mm according to customer requirements
