POF is a heat shrinkable film mainly used for packaging regular and irregular shaped products

1. Safe POF shrink packaging, soft corners, will not scratch hands, but also resistant to friction.
2. Environmentally friendly, hygienic and non-toxic, processing does not produce toxic odor, basically replacing PVC heat shrinkable film and becoming the mainstream product in heat shrinkable packaging materials.

3. Thin and tough, with uniform thickness, good moisture resistance and soft texture. High tensile strength, tear resistance, adjustable shrinkage. Low density polyethylene has good friction properties.
4. It has processing performance. It does not produce moisture or stick to the sealing rod during processing, which is convenient for maintenance and operation. High toughness, smoothness and friction resistance, suitable for automatic packaging in high-speed production lines.
5. It has excellent physical properties such as cold resistance. It is not hard or brittle at -50 °C, and it is not easy to break. It can be used for frozen food packaging. After shrink packaging, it can be stored at -50℃-95℃ for a long time, and the performance is stable. With electrostatic and anti-fog treatment, it is not easy to pollute the dust, and it can keep the product clean and bright.

POF shrink film main performances

  1. The common thickness of POF shrink film is 15-35micron, and the density is 0.92. Both of MD and TD shrinkage rates of POF shrink film are both about 55%.
  2. POF shrink film has high transparency, uniform thickness, good toughness and high tear resistance. Due to the soft texture of POF shrink film and high printing requirements, the printing color of POF heat shrinkable film is relatively simple.
  3. POF shrink film is not easy to be stained with dust, and it is mostly packaged with a flat mouth. After POF shrink film is packaged, the four corners of the seal are soft. Generally, it is not easy to process into other shapes and does not pack heavy objects.
  4. POF shrink film has excellent cold resistance. It is not easy to crack at -50°C. Therefore, POF shrink film is an ideal packaging material for frozen food.
  5. POF shrink film is a special production tool that adopts advanced bidirectional stretching three-layer melt co-extrusion.It does not produce toxic odor during processing, and meets the standards of FDA.

Heat Shrink Film application

Shrink film is widely used in: food, medicine, disinfection tableware, stationery, craft gifts, printed matter, hardware and plastic products, telephones, electronic appliances and other products, especially in the combination of irregular shaped items or commodities In terms of packaging, it can not only meet the functions of moisture-proof and dust-proof, anti-touch and secret replacement, transparent display, etc., but also increase the attractiveness of the product appearance. It can also be used to replace various types of cartons, which not only saves packaging costs, but also conforms to the packaging trend. Shrink film (bag) can be processed into: flat bag, arc bag, trapezoid bag, three-dimensional bag and other special-shaped bags.
