The same is the heat shrinkable film, why the POF heat shrinkable film is better than others

It is also a heat shrinkable film. Why is POF heat shrinkable film better than others? The difference and advantages of Shenzhen POF heat shrinkable film and other shrinkable films; cost POF proportion 0.92, the thinnest thickness is 0.012mm, the actual unit cost is lower. PE proportion is 0.92, the thickness is more than 0.03, the actual unit cost is higher. PVC proportion is 1.4 , The thinnest thickness is 0.02mm, and the actual unit cost is relatively high. The physical properties of POF are thin and tough, the thickness is uniform, the moisture resistance is good, and the texture is soft. The tensile strength is high, the tear resistance is large, and the shrinkage rate is adjustable. Because of the existence of LLDPE, it is resistant to rubbing Better. PE is thick and tough, uniform thickness, good moisture resistance, soft texture. The tear resistance is lower than POF, but much higher than PVC, and the shrinkage is poor. The rubbing resistance is not as good as POF. PVC is thick and brittle, thick and thin Uneven, poor moisture resistance, hard and brittle texture. Low strength, low shrinkage, poor resistance to rubbing. Physical properties such as cold resistance. POF has excellent cold resistance. It is not hard or brittle at -50°C and is not easy to break. It can be used for frozen food packaging. After shrink packaging , -50℃--95℃ The packaged materials are stored for a long time and remain stable. It has static electricity and anti-fog treatment, which is not easy to pollute dust, and can keep the product clean and beautiful. PE has excellent cold resistance, and will not harden after winter or freezing. It is not brittle, so it is not easy to break during transportation. With static elimination treatment, it is not easy to stain and can keep the product clean. PVC is extremely cold resistance, and it will become brittle in winter or freezing, so it is easy to break during transportation. The longer the shrink packaging, the shrink It will become tighter, and the package will be deformed. No static elimination treatment, easy to be contaminated with dust, and blurred product contamination. Processing performance POF processing process does not produce water or stick to the sealing rod, maintenance and operation are easy. High toughness, smoothness And anti-rubbing properties make it suitable for automatic packaging on high-speed production lines. PE processing does not produce moisture, nor stick to the sealing rod, easy maintenance and operation. High toughness, low rubbing, can be used for automatic packaging on higher-speed production lines. PVC processing The process will produce volatile matter, which is easy to cause mechanical damage, and it is easy to stick to the sealing rod. It is inconvenient to work and difficult to maintain. After the safety POF shrink packaging, the four corners of the seal are soft, will not cut hands, and are resistant to rubbing. PE shrinks After packaging, the four corners of the seal are soft and will not cut human hands. After PVC shrink packaging, the four corners of the seal are hard and sharp, which is easy to cut and bleed. Environmentally friendly and sanitary POF is non-toxic, does not produce toxic odors during processing, and meets US FDA and USDA standards. PE is non-toxic, does not produce toxic gas during processing, and meets the U.S. FDA and USDA standards. PVC is toxic, processing will produce odor and toxic gas, and it is gradually banned.
