The shrink film is used in conjunction with the heat shrink machine. The texture is relatively brittle. After the heat shrink machine is turned on, blow it against the shrink film, and the shrink film will shrink. If you handle it properly, it will look good; the texture of the stretch film is relatively soft, it is entangled on the outside during the pallet.
Shrink film is used in the sales and transportation process of various products. Its main function is to stabilize, cover and protect the product. The shrink film must have high puncture resistance, good shrinkage and a certain shrinkage stress. During the shrinking process, the film cannot produce holes. Since shrink film is often used outdoors, it is necessary to add UV anti-ultraviolet agent.
Shrink 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 the combination of irregular shaped items or commodities in terms of packaging, it 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 meets packaging trends.
Shrink film (bag) can be processed into flat bags, arc-shaped bags, trapezoidal bags, three-dimensional bags and other special-shaped bags.
Stretch film is an industrial packaging film, with high tensile strength, high elongation, good self-adhesiveness, and high transparency. It can be used for manual stretch film and machine stretch film, which can be widely used in centralized packaging of various goods. Stretch film is mainly mixed and extruded from several different grades of polyolefin resin. It has puncture resistance, super strength and high performance. It wraps the goods stacked on the pallet to make the package more stable, tidy, stronger and waterproof, so it is widely used in foreign trade, papermaking, hardware, plastic chemicals, building materials, food and medicine industries.
Stretch film and plastic film have general properties, and the stretch film specially configured with tackifier is more professional. It is heated, squeezed, cast, and then cooled by chill rolls. It has strong toughness, high elasticity, and tear, high viscosity, thin thickness, cold resistance, heat resistance, pressure resistance, dustproof, waterproof, single-sided adhesive and double-sided adhesive, etc., can save materials, labor, and save time during use. It is widely used in papermaking, logistics, chemicals, plastic materials, building materials, food, glass, etc.
