The difference between POF heat shrinkable film and PVC heat shrinkable film

1. Cost difference: The specific gravity of POF is 0.92, the thickness is 0.012mm, and the actual unit cost is lower. The specific gravity of PVC is 1.4, and the thickness is the thinnest 0.02mm, the actual unit cost is higher. 2. Physical difference: POF is thin and tough, with uniform thickness and soft texture. High tensile strength, high tear resistance, adjustable shrinkage, better rub resistance. PVC is thick and brittle, with uneven thickness, poor moisture resistance, and hard and brittle texture. Low strength and poor rub resistance. 3. Safety difference: The four corners of the POF shrink packaging are soft, will not cut hands, and are resistant to rubbing. After PVC shrink packaging, the four corners are hard and sharp, which is easy to cut and bleed. 4. Environmental protection difference: POF is non-toxic and does not produce toxic smell during processing. PVC is toxic and will produce odor when processed.

Suitable for semi-automatic or fully automatic shrink packaging machine. PVC shrink film has a wide range of functions: packaging of various commodities such as wine, food, sports goods, sterilized tableware, electronic appliances, daily necessities, handicrafts, maintenance products, stationery, toys, plastic hardware, glass ceramics, etc. Heat-shrinkable film manufacturers, POF heat-shrinkable film, heat-shrinkable film sealing operation, and possible cause analysis of the printing color difference of food packaging bags
