POF heat shrinkable film

POF is a kind of heat shrinkable film, mainly used for packaging products with regular and irregular shapes. Due to its non-toxic and environmental protection, high transparency, high shrinkage, good heat-sealability, high gloss, toughness, tear resistance, It has the characteristics of uniform heat shrinkage and suitable for automatic high-speed packaging. It is a replacement product of traditional PVC heat shrinkable film. It is widely used in automotive supplies, plastic products, stationery, books, electronics, circuit boards, MP3, VCD, handicrafts, photo frames and other wood products , Toys, pesticides, daily necessities, food, cosmetics, canned beverages, dairy products, medicine, cassettes and video tapes and other products.

Main features:

1. High transparency and good gloss, which can clearly display the appearance of the product, improve the sense of perception, and reflect the high-end.

2. The shrinkage rate is large, up to 75%, and the flexibility is good. It can package any shape of goods. And the shrinkage force of the three-layer co-extruded film treated by a special process is controllable, which can meet the shrinkage force of different product packaging. Claim.

3. Good welding performance and high strength, suitable for manual, semi-automatic and high-speed automatic packaging.

4. It has good cold resistance and can maintain flexibility at -50°C without embrittlement. It is suitable for storage and transportation of the packaged materials in a cold environment.

5. Environmentally friendly, non-toxic, in line with US FDA and USDA standards, and can package food. The main raw materials of the three-layer co-extruded heat shrinkable packaging film include LLDPE (linear low-density polyethylene), TPP (ternary copolymer polypropylene), PPC (binary copolymer polypropylene) and necessary functional additives such as Shuang Slip agent, anti-blocking agent, antistatic agent, etc. These raw materials are environmentally friendly and non-toxic materials, no toxic gas or odor will be generated during processing and product application, and the product’s hygienic performance meets the US FDA and USDA standards, and can be used to package food.

Production process edit Three-layer co-extrusion heat shrinkable packaging film is made of linear low density polyethylene (LLDPE) and copolymer polypropylene (TPP, PPC) as the main raw materials, adding necessary additives, and processed by co-extrusion blow molding. The process is different from the traditional blow molding process. Due to the poor tensile properties of the PP melt state, the traditional blow molding process cannot be used. Instead, the double bubble process is used, which is also known as the Pulandi process in the world. It is melted and extruded by different extruders, through a specially designed co-extrusion die head, the primary film is formed and then quenched, and then heated for secondary inflation and stretching to obtain the product.

Main performance editing product specifications

Three-layer co-extruded heat shrinkable film can be produced in various specifications according to the application. The general thickness ranges from 12μm to 30μm. Common thicknesses are 12μm, 15μm, 19μm, 25μm, etc. The width specifications depend on the volume of the package. Cold resistance  The three-layer co-extruded heat-shrinkable packaging film remains soft at -50°C, without brittleness, and is suitable for storage and transportation of the packaged material in a cold environment. Hygienic performance  The raw materials used in the three-layer co-extruded heat shrinkable packaging film are all environmentally friendly non-toxic materials, and the processing and use process are hygienic and non-toxic, complying with national FDA and USDA standards, and can be used for food packaging.

Application prospect editing

POF heat shrinkable packaging film has a wide range of uses, a broad market, and has the advantages of environmental protection and non-toxicity. Therefore, it has received extensive attention from developed countries in the world and has basically replaced PVC heat shrinkable packaging film as the mainstream product of heat shrinkable packaging materials. The production of this series of products in my country began in the mid-1990s. At present, there are more than ten production lines in China, all of which are imported equipment, with a total production capacity of about 20,000 tons. Due to a certain gap between my country’s packaging technology and internationally developed countries, the application of three-layer co-extrusion series of heat-shrinkable packaging films in China is still at a preliminary stage, and the scope of application is still relatively narrow, limited to beverages, audio-visual products, convenience foods and a small amount of daily chemical products In a few areas, the annual demand is about 2 to 50,000 to 30,000 tons. 

Features of heat shrinkable film

The materials used for heat shrinkable films are mainly various thermoplastic films. At first, PVC shrink film was mainly used. With the continuous development of market demand, PVC shrink film gradually decreased, and various PE, PP, PET, PVDC, POF and other multilayer co-extruded heat shrink films developed rapidly and became the mainstream of the market. Heat shrinkable film is used in the sales and transportation of various products, and 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.

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 for easy 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, waterproof 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.

PE heat shrinkable film application scope: 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.
