The causes of air leakage can be attributed to the following points:
1. The heat sealing temperature of CPP is higher than that of LDPE, so it is easy to leak in the crease of the back seal when the heat sealing temperature of CPP is higher than that of LDPE. It is easier to obtain good sealing performance by using CPP which can be sealed at low temperature.
2. The rough mold or other reasons that press through the packaging material will also cause air leakage of the packaging bag.
3. Inflation should vary according to the sales area. For example, the inflatable packaging sold to high altitude areas may expand the volume of the packaging bag due to the decrease of atmospheric pressure, and some of the bags may even burst and leak.
