POF heat shrinkable film is especially suitable for packaging products with special needs

POF heat shrinkable film cross-linked film is a kind of shrink film (POF shrink film heat shrinkable film can be divided into three types: ordinary film, high-end film, and crosslinked film). POF shrink film cross-linked film is suitable for mechanical packaging, especially for packaging products with special needs, such as lottery tickets, banknotes, electronic products, etc. The cross-linked film has a better shelf effect. It should be used with a heat shrinking machine. The texture is relatively brittle. After the heat shrinking machine is turned on, blow it against the shrink film, and the shrink film will shrink. If you operate it properly, it will look good; It was entangled outside during the pallet. It is designed with the principle of stretching and orientation of polymer molecular chain and formed by quenching and shaping. The physical principle is: when the polymer is in a highly elastic state, stretch the orientation, and then quench the polymer to below the glass transition temperature, the molecular orientation is frozen, when the article is heated during packaging , Due to the stress relaxation caused by the thermal movement of the molecules, the points are restored to their original state and contraction occurs. Shrink film is a kind of packaging film with transparent gloss and close to the appearance of goods. Its characteristics of energy saving, environmental protection, high shrinkage, transparent gloss, strong tear resistance, etc. overturn the limitations of traditional packaging films, and are well received by the market. Welcome, much loved by consumers. POF shrink film is suitable for a variety of packaging fields, including packaging in the food field, daily necessities field, cosmetics field and so on. POF shrink film is a highly automated equipment. The product is widely used in daily necessities, food and beverages and household chemicals. The application of heat shrink film packaging machine can greatly reduce the material and labor costs of medium box packaging, which has important economic significance . The packaging machine is currently the latest type of shrink packaging equipment in China. It can enable enterprise products to enter the market better and faster, bringing high benefits and high returns to individuals or enterprises. More info
