The commodity standard of vacuum food packaging bag is significantly higher than that of ordinary industrial goods
The standard of vacuum food packaging bag is significantly higher than that of ordinary industrial goods. Vacuum food packaging bag is a common kind of packaging in plastic flexible packaging. Compared with ordinary plastic packaging bag, it has obvious advantages in packaging performance, environmental protection performance and aesthetic degree, For vacuum packaging bags, the most worrying problem is that after a period of storage, the vacuum packaging bags will swell and lose the significance of food packaging bags. Then what causes this situation? Let's take a look
1. The material used in the packing bag is unqualified: both nylon and polyester can be used as raw materials for vacuum packaging bag. The difference is that nylon is better than polyester in barrier property. If the bag you made to order appears to swell after half a month, you can consider whether you chose the wrong material when you made the vacuum bag;
2. Incomplete sterilization during use: if the material of the food packaging bag is OK, you can consider whether it is caused by incomplete sterilization and rapid propagation of bacteria in the bag. This situation usually occurs in the use of vacuum packaging of meat products. The inspection method is very simple. Use the bag to pack appropriate amount of rice (generally, there is no aerogenic bacteria) in the bag After half a month of storage, if there is no bag swelling phenomenon, it indicates that it is caused by incomplete sterilization in the process of using the vacuum bag. At this time, you can adjust the sterilization process; if the above problems are solved, the problem of bag swelling will not occur again if the vacuum packaging bag is used correctly. http://www.dgbpk.com/
