What are the reasons for the leakage of vacuum packaging bags

For wholesale vacuum packaging bags, the problem that is worried about is that the vacuum packaging bags will swell after being placed for a period of time. This loses the meaning of vacuum packaging. Do you know the reason for this? The following is an analysis of the four major reasons why ChouQin packaging bag manufacturers have leaked and swelled wholesale vacuum packaging bags.
1. Bacteria multiplying in the vacuum packaging bag will often produce gas, which is one of the reasons for the bag swelling of food.
Wholesale vacuum packaging bags, if the material of the vacuum packaging bag is okay, you can consider whether it is due to incomplete sterilization and rapid propagation of bacteria inside. This situation usually occurs in vacuum packaging of meat products. In use, the inspection method is very simple. Use the bag to fill the appropriate amount of rice (rice generally does not have aerobic bacteria) and leave it for half a month after vacuuming. If there is no phenomenon of bag expansion, it means that it is in the process of using the vacuum packaging bag. It is caused by incomplete sterilization. At this time, you can adjust the sterilization process.
2. The airtightness of the vacuum packaging bag and the permeability of the vacuum packaging bag. After the food is bagged, the vacuum packaging bag needs to be heat-sealed in the next process, and the quality of this process will directly affect the sealing performance of the vacuum packaging bag. If the edge is not tightly sealed after the rim, the packaging bag will leak air, and air will penetrate into the vacuum packaging bag from the leaking part of the packaging bag. The permeability of the vacuum packaging bag is too large, which is another reason that causes the food bag to swell.
3. During the transportation process and the storage temperature of the seller's warehouse, many products are caused by the intermittent room temperature exceeding 37 degrees Celsius, which is cold and hot, and condensed water is generated inside.
4. Wholesale vacuum packaging bags produce gas through reaction between food additives or between food additives and ingredients to produce gas.
