POF heat shrinkable film is one of the most popular environmentally friendly heat shrinkable films in the world

POF heat shrinkable film is one of the most popular environmentally friendly heat shrinkable films in the world. The main downstream application fields of domestic food, cosmetics and other POF films have maintained a growth rate of about 20%, and there are still many new market applications for POF films that need to be expanded in the future. It is expected that in the next three years, the domestic POF heat shrinkable film market will maintain an average annual growth rate of 13.40%. POF heat shrinkable film is the abbreviation of biaxially oriented polyolefin shrink film, which is currently the most widely used and rapidly developing in the world New environmentally friendly shrink film. What is the difference between it and the commonly used PVC heat shrink film? The same point 1. All can shrink when heated. 2. All are transparent. 3. Both can be made into shrink bags. 4. All can be shrunk with shrink machine. Differences 1. The shrinkage temperature of PVC should reach 100-120 degrees, and the shrinkage temperature of POF should reach 140-160 degrees. 2. Because the shrinkage temperature requirements are different, PVC can be blown and shrinked with a household hair dryer, and POF should at least be used Hot air gun. Therefore, those who use the hair dryer at home to achieve the shrinkage effect, buy PVC material shrink film and shrink bag. 3. The finished product of PVC heat shrinkable film is cylindrical, and the finished product of POF heat shrinkable film is double-folded and single-piece, not cylindrical. 4. PVC can be made into two-end shrink carrier and arc bag, POF is not easy to make now. Shrink cut pieces and arc pockets with both ends. The POF processing process does not produce moisture or stick to the sealing rod, and it is easy to maintain and operate. High toughness, smoothness and rub resistance make it suitable for automatic packaging in high-speed production lines. The PE processing process does not produce moisture and does not stick to the seal It is easy to maintain and work on the stick. It has high toughness and low rubability, and can be used for automatic packaging on higher-speed production lines. The PVC processing process will produce volatile matter, which is easy to cause mechanical damage, and it is easy to stick to the sealing rod, which is inconvenient to work and difficult to maintain . POF heat shrinkable film has many advantages of polyethylene (PE) and polypropylene (PP) films. In contrast, its packaging has better skin-fitting effect, higher transparency, better toughness, and a larger packaging area per unit weight. Big. At present, POF heat shrinkable film is gradually replacing other packaging materials such as PE and PP in some fields. The production process of POF heat shrinkable film is non-toxic and consumes less raw materials per unit area. It will become the most environmentally friendly plastic packaging material with the most development potential in the future.
