Characteristics and applications of POF heat shrinkable bag

Heat shrink film is used in the sale and transportation of a variety of products, its main role is to stabilize, cover and protect products. Shrinkage film must have high puncture resistance, good shrinkage and a certain shrinkage stress. During shrinkage, the film cannot create holes. Because shrink film is often used outdoors, it is necessary to add UV anti-UV agent.

POF heat shrink bag

POF surface gloss, toughness, tear strength, uniform thermal shrinkage and suitable for automatic high-speed packaging, etc., is the replacement of traditional PVC thermal shrinkage film. The full name of POF is multi-layer co-extruded polyolefin heat shrink film. It is made of linear low-density polyethylene as the intermediate layer (LLDPE), copolypropylene (pp) as the inner and outer layer, plasticized and extruded by three extruders, and then processed by die head molding, film bubble blowing and other special processes.

POF thermal shrinkable bag has high flexibility, not easy to damage, strong bursting resistance, impact resistance, tear resistance, tensile strength, can replace box packaging.

The shrinkage rate is large, it can tightly wrap the articles after thermal shrinkage. If it is made into PE straight through bag (the two ends of the bag open) after thermal shrinkage, the two ends of the open can lift the articles, which can bear the weight of 15KG, easy to handle.

High transparency, light transmittance up to 80%, can display the product, in the invisible publicity of products, but also reduce the distribution error in the circulation link.

Moisture-proof, water-proof, dust-proof, can not only achieve the packaging effect, but also beautiful products, protect products. Non-toxic, tasteless and pollution-free is an environmentally friendly packaging material.

Heat shrink bag is widely used in food, medicine, disinfection tableware, stationery, craft gifts, printed matter, hardware and plastic products, telephone, electronic and electrical appliances and other products, especially in the irregular shape of the articles or commodities combined (cluster) packaging, can not only meet the goods moisture-proof and dustproof, anti-touch smuggling, transparent display and other functions. It can also increase the appearance attraction of products, and can also be used to replace all kinds of cartons, not only save packaging costs, but also conform to the packaging trend. Shrink film (bag) can be processed into: flat pocket, circular arc bag, trapezoidal bag, three-dimensional bag and other special-shaped bags.

In our life also often need to use the heat shrinkable bag, for example, when we move, the soles are dirty, this time the heat shrinkable film can avoid dirty luggage, but also better transportation.
