1. Cost difference: The specific gravity of POF is 0.92, the thickness is the thinnest 0.012mm, and the actual unit cost is lower. The specific gravity of PVC is 1.4, the thickness is the thinnest 0.02mm, and 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 strength, 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. Difference in safety: The four corners of POF shrink-wrapped are soft, will not cut hands, and are resistant to rubbing. The four corners are hard and sharp after PVC shrink packaging, which is easy to cut and bleed.
4. Environmental protection difference: POF is non-toxic and does not produce toxic odor during processing. PVC is toxic and processing will produce odor.

The scope of POF shrink film: widely used in the outer packaging and collective packaging of cosmetics, gifts, medicines, audio and video products, wood products, plastic hardware, daily necessities and other industries. Suitable for semi-automatic or fully automatic shrink wrapping machines.

PVC shrink film has a wide range of functions: packaging of various commodities such as wine, food, sporting goods, disinfection tableware, electronic appliances, daily necessities, handicrafts, maintenance products, stationery, toys, plastic hardware, glass ceramics, etc.
