What is POF shrink film?
POF is a kind of heat shrinkable film, which is mainly used for packaging products with regular and irregular shapes. Because of its non-toxic, environmental protection, high transparency, high shrinkage, good heat sealing performance, high gloss, strong toughness, tear resistance, uniform heat shrinkage and suitable for automatic high-speed packaging, POF is a replacement product of traditional PVC heat shrinkable film, which is widely used in automotive supplies, plastic products, stationery, books, electronics, circuit boards, MP3, VCD, handicrafts, etc.
POF highly adaptable shrinkage film
Characteristics of POF shrink film products
1, high transparency, good gloss, can clearly show the appearance of products, improve sensory awareness, reflect high grade.
2. The shrinkage rate is high, up to 75%, and the flexibility is good, which can be used for packaging any shape of goods. Moreover, the shrinkage force of the three-layer coextruded film after special processing is controllable, which meets the requirements of different commodity packaging for shrinkage force.
3. Good sealing performance and high strength, suitable for manual, semi-automatic and high-speed automatic packaging.
4. It has good cold resistance, can keep flexibility at-50℃ without brittle fracture, and is suitable for being stored and transported in cold environment.
5. Environmentally friendly, nontoxic, in line with FDA and USDA standards, and capable of packaging food.
Introduction of main raw materials of POF shrinkage film
The main raw materials of the five-layer coextruded heat shrinkable packaging film include LLDPE (Linear Low Density Polyethylene), TPP (Ternary Copolymer Polypropylene), PPC (Binary Copolymer Polypropylene) and necessary functional auxiliaries such as slip agent, anti-blocking agent and antistatic agent. These raw materials are environment-friendly and non-toxic materials, which will not produce toxic gas and peculiar smell during processing and product application. The hygienic performance of the products meets FDA and USDA standards, and can be used for packaging food.
Introduction of POF shrink film production process
Five-layer co-extrusion heat shrinkable packaging film is made of linear low density polyethylene (LLDPE) and copolymerized polypropylene (TPP, PPC) as main raw materials and added with necessary additives. The process is different from the traditional blow molding process. Due to the poor tensile properties of PP melt, the traditional blow molding process can not be adopted, but the double bubble process, also known as Prandi process in the world, which melts and extrudes raw materials through different extruders and adopts special design
Introduction of main properties of POF shrink film products
Product specification
Five-layer co-extruded heat shrinkable film can be produced in various specifications according to its application, with a general thickness ranging from 12μm to 30 μ m, and commonly used thicknesses of 12 μ m, 15μm, 19μm, 25μm, etc. The width specification depends on the package volume.
cold tolerance
The five-layer co-extruded heat shrinkable packaging film keeps soft at-50℃, does not produce brittle fracture, and is suitable for the storage and transportation of packaged goods in cold environment.
Hygienic performance
The raw materials of the five-layer co-extruded heat shrinkable packaging film are all environment-friendly and non-toxic materials, which are sanitary and non-toxic during processing and use, meet the national FDA and USDA standards, and can be used for food packaging.
Introduction of application range of POF shrinkage film
POF heat shrinkable packaging film is widely used, has a broad market and has the advantages of environmental protection and non-toxicity, so it has been widely valued by developed countries in the world, and has basically replaced PVC heat shrinkable packaging film as the mainstream product in heat shrinkable packaging materials. The production of this series of products in China began in the mid-1990s. 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. Because there is a certain gap between China's packaging technology and developed countries, the application of three-layer co-extrusion series heat shrinkable packaging film in China is still in the initial stage, and its application scope is still narrow, which is limited to a few fields of beverages, audio-visual products, convenience foods and a small amount of daily chemical products, with an annual demand of about 2? 50,000 ~ 30,000 tons. PVC heat shrinkable film also occupies a considerable market of heat shrinkable packaging, with great development potential. With the integration of China's entry into WTO with the international market, the gradual improvement of packaging requirements for a large number of export commodities, and the rapid development of domestic supermarkets, the application of three-layer
