heat shrink film

Release time:2024-03-28

Heat shrink film is a kind of heat shrink molding film used for packaging, which is characterized by its ability to shrink when heated, tightly wrapped around objects to protect them, with high puncture resistance, good shrinkage and a certain shrinkage rate. Mainly used as a variety of food packaging for transportation and sales, the heated film can be tightly adhered to the surface of the product, cover and protect the product beautiful.

The main use of heat shrink film on the market is divided into three kinds, respectively, PE heat shrink film, PVC heat shrink film, POF heat shrink film.

PE heat shrink film is widely used in alcohol, cans, mineral water and beverages and other products of the whole collection of packaging, PE heat shrink film has good flexibility, impact resistance, tear resistance, not easy to break, not afraid of moisture, shrinkage rate. At the same time, due to the characteristics of PE, most of the film can be recycled by the recycling of granulation and then blow molded into film use, greatly reducing costs.

PVC heat shrink film should be its unique properties (rain, fire, anti-static, easy to mold) and lower input costs, is widely used in the building materials industry and packaging industry. pvc film itself, high transparency, good gloss, high shrinkage, but because of the characteristics of polyvinyl chloride, making itself not environmentally friendly, so not yet in the field of food and other areas of use.

POF heat shrinkable film as a substitute for traditional PVC heat shrinkable film, due to its non-toxic environmentally friendly, high transparency, high shrinkage, good heat sealing performance, high gloss, strong toughness, tear resistance, heat shrinkage uniformity and suitable for automatic high-speed packaging and other characteristics, in recent years the market occupancy rate has gradually increased, and can be applied to a variety of industries.

The heat shrink film production line produced by our company uses special heat shrink film molds with large blowing ratio, which has a larger output and more excellent winding effect.
