POF shrink film and PVC shrink film are two common materials in the packaging industry, and they are different in material, characteristics and use.
First of all, from the perspective of material, POF heat shrinkable film is a new environmentally friendly material copolymerized by polypropylene and ethylene oxide, which has excellent heat shrink performance and high transparency; PVC heat shrinkable film is made of polyvinyl chloride, which is softer than POF film, but has relatively low transparency.
Secondly, from the perspective of characteristics, POF heat shrinkable film has good tear resistance and high temperature resistance, is not easy to produce harmful gases, and has a good preservation effect. PVC heat shrinkable film is easy to be deformed by heat, and is not resistant to high temperature, and is easy to produce harmful gases, so it needs to be used with caution in some specific occasions.
Finally, from the perspective of use, due to its higher transparency and high temperature resistance, POF film is often used in packaging in food, medicine and other fields, which can effectively protect the quality and hygiene of products; PVC film is mostly used for daily necessities, gifts and other packaging, and can also be used as a printing material.
To sum up, POF heat shrinkable film and PVC heat shrinkable film have their own unique advantages and application scenarios, and it is necessary to make a reasonable choice according to the actual needs when choosing to ensure the packaging effect and product quality.
