Frozen vacuum packaging bag has relatively good impact resistance. Frozen food needs to be transported, loaded, unloaded placed on shelves after vacuum packaging. In these processes, frozen food vacuum packaging bag is easy to be damaged by external forces. If the impact resistance of frozen food vacuum packaging bag is poor, it is easy to break open the bag, which only affects the appearance of packaging products, but also It can play the role of packaging itself.
Moreover, the smoothness is good, the smoothness of the vacuum packaging bag itself is good. In the production process, the opening is poor, the production efficiency is low. At the same time, the utilization rate of the vacuum packaging bag will be reduced, resulting in waste of cost. It is a kind of vacuum bag with good heat sealing strength. The insufficient heat sealing strength high heat sealing temperature of the vacuum bag cause damage to the heat sealing layer, reduce the protection performance of the vacuum bag, greatly shorten the shelf life of the contents, make the contents fail to reach the corresponding shelf life.
In addition, due to the high peeling strength, good tensile strength poor mechanical properties of vacuum bags, the delamination of vacuum bags the failure of vacuum bags to achieve the load-bearing function effectively protect the contents cannot be achieved. In addition, it has good cold resistance. If the vacuum packaging bag fails to meet the requirements, it can maintain the original performance of the material at a low temperature. The packaging material is brittle, which reduces the mechanical strength of the packaging material, causes the vacuum packaging bag to break crack, can meet the protection of the contents.
