Advantages of vacuum packaging bags

Frozen vacuum packaging bag, it has relatively good impact resistance characteristics, frozen food after vacuum packaging also need to transport, loading and unloading, shelf placement, etc., these processes of frozen food vacuum bags are vulnerable to external force damage, if the frozen food vacuum packaging bag resistance is poor it is easy to break the bag, open the bag phenomenon, not only affects the appearance of packaging products, At the same time, it can not play the role of packaging itself.

Moreover, the smoothness is good, the smoothness of the vacuum bag itself is not good, the production process is characterized by poor opening, low production efficiency, and it will also reduce the utilization rate of the vacuum bag and waste the cost. It is a vacuum bag with good heat sealing strength, the heat sealing strength of the vacuum bag is not enough, the heat sealing temperature is too high, resulting in the damage of the heat sealing layer, resulting in the protective performance of the vacuum bag is reduced, the shelf life of the contents is greatly shortened, so that the contents can not reach the corresponding shelf life.

There are also high inter-layer peeling strength, good breaking force, and poor mechanical properties of the vacuum bag, resulting in the stratification of the vacuum bag, the vacuum bag can not achieve the due load-bearing role, and the content can not play an effective protection role. In addition, its cold resistance is good, if the vacuum packaging bag does not meet the requirements, in the case of low temperature, can not maintain the original performance of the material, the packaging material is brittle, so that the mechanical strength of the packaging material decreases, resulting in the vacuum packaging bag rupture and cracking, but can not meet the protection of the contents.
