Scope of application

The Heat Shrinkable Film uses far-infrared radiation to directly heat various specifications of film. The product is transported to the shrinking furnace through the conveyor belt, and the product is loaded with the shrink packaging film. After sealing, it enters the shrink packaging machine, and the product automatically shrinks. The heat shrink packaging machine consumes little power , The average hourly power consumption is only 2.1KW, to achieve perfect shrink packaging effect, never affect the packaging, electronic continuously variable speed, solid-state voltage regulator temperature control, stable and reliable, used in food, beverages, candy, stationery , Hardware tools, daily necessities, chemical supplies, etc. heat shrink.


Heat shrinkable film is widely used in the outer packaging of various products such as food, medicine, sterilized tableware, stationery and sports goods, craft gifts, printed matter, hardware and plastic products, telephones, electronic appliances, etc., especially in irregularly shaped items or commodities. Combination (cluster) packaging can not only meet the functions of moisture-proof, dust-proof, touch-proof, transparent display, etc., but also increase the attractiveness of the product's appearance. It can also be used to replace all kinds of cartons, which not only saves packaging costs, but also In line with packaging trends. Shrink film (bag) can be processed into: flat bags, arc-shaped bags, trapezoidal bags, three-dimensional bags and other special-shaped bags.


It has high flexibility, not easy to break, strong blast resistance, strong impact resistance, strong tear resistance, strong tensile force, and can replace box packaging.

The shrinkage rate is large, and the items can be tightly wrapped after heat shrinking. If the PE pass-through bag (opening at both ends of the bag) is heat-shrinked, the two ends of the opening can lift the items, which can bear a weight of 15KG, which is convenient for handling.

It has good transparency and 80% light transmittance. It can display products and promote products invisibly. At the same time, it also reduces distribution errors in the logistics link.

Moisture-proof, water-proof and dust-proof, it can not only achieve the packaging effect, but also beautiful and protect the product.

Non-toxic, tasteless, and pollution-free are environmentally friendly packaging materials.

Application scope of heat shrinkable film: medicines, beverages, mineral water, beer, laminate flooring, palletizing, building materials, metal products, dairy products, glass bottles, industrial paper and other large-scale packaging equipment, articles, etc.
