The function of pvc shrink film

    PVC has high flexibility, strong tear resistance and tensile strength, and can replace carton packaging. The shrinkage rate is high, and the goods can be tightly wrapped after thermal contraction, which is convenient to carry. The transparency of the product is good, and the light transmittance reaches 80 to show the product, which virtually enhances the product. Moisture-proof, waterproof and dustproof, which can not only achieve the packaging effect, but also beautify and protect products.

    Pvc is widely used in the outer packaging of doors and windows, building materials, food, medicine, sterilized tableware, stationery, handicrafts, printed matter, hardware and plastic products, electronic appliances, etc., especially the combination (cluster) packaging of irregularly shaped articles or commodities, which can not only meet the functions of moisture-proof, dust-proof, touch-proof, theft-proof and transparent display of products, but also increase the attractiveness of products. It can also be used to replace various cartons, which not only saves the packaging cost, but also conforms to the packaging trend. Shrink film (bag) can be processed into special-shaped bags such as flat bags, arc bags, trapezoidal bags and three-dimensional bags.

    The diversification of pvc is not only suitable for the packaging of various products and pallets, but also convenient for transportation and sales. It is easy to realize mechanization, save manpower and material resources, and can partially replace carton and wooden box packaging. Heat shrinkable film is used to pack bottled beer, instead of tying it with rope, to prevent the bottled beer from exploding and hurting people. It has been widely used in doors and windows, building materials, ceramic products, tea sets, mechanical parts and other fields. The application of heat shrinkable film and gas phase antirust technology instead of antirust oil in military machinery and hardware tools is of great significance to improve the antirust ability.
