What are the performance requirements of POF shrink film?

Because the processing and manufacturing method of POF shrink film is different from general film, and the packaging application method of its heat shrinkage is also quite special. Therefore, the film itself has extremely high performance requirements.　　 Low shrinkage temperature: to facilitate the end user to increase the packaging speed and reduce packaging costs.　　Wide shrinkage temperature working range: Improve the machineability of the film, so that the film can be easily applied to a variety of new and old design shrink packaging equipment, without the need to greatly adjust the packaging conditions.　　 Appropriate shrinkage rate and shrinkage force: Different package contents may need different shrinkage properties to match, and must be adjusted by formula and processing conditions.　　High heat-sealing strength and heat-adhesive strength: For high-speed automatic packaging equipment, higher heat-bonding and heat-sealing strength are especially important, which can effectively reduce the leakage rate of packaging. High mechanical strength: higher tear strength, puncture strength and impact strength, which can reduce the leakage rate of the package, and provide higher protection for the contents. High transparency and surface gloss: make the contents of the package look more Beautiful, enhance product attractiveness, and stimulate consumers' desire to buy.　　 Label: p0f heat shrinkable film
