the vacuum package leaks and can’t be eaten. Because vacuum packaging is to prevent the entry of air and oxidation, so as to prevent decay. If the vacuum packaging leaks, it proves that the air has entered, so the goods may have deteriorated

causes of air leakage in vacuum packaging:

1. The shape of the product is not standardized

the shape is irregular and there are convex parts, which is easy to puncture the bag or tie it into an air leakage port

2. The bag is unqualified

the quality of the bag is poor, or the thickness and size of the bag are inappropriate, or the size of the box is inappropriate

3. The bag is too thin

when vacuumizing excessively, the bag will stretch and deform in the protruding part of the product, and serious pinholes will appear

4. Uneven sealing

when sealing the bag, pay attention to keep it flat to prevent discount, because pinholes will also appear at the discount. It may be handled by appropriately increasing the heat sealing temperature or prolonging the heat sealing time, but it can not be completely avoided

extended data:

shelf life of vacuum packaging:

1. Vacuum packaging must be frozen at – 40 degrees and then stored at – 18 degrees before it can be stored for about three months

2. If preservatives are added to cooked food products, they can generally be stored for 15 days in vacuum packaging and 30 days in low temperature storage. However, if no preservatives are added, they can only be stored for 3 days in vacuum packaging and low temperature storage. After three days, they will have a much worse taste and taste

3. Some products will have a retention period of 45 days or even 60 days written on the packaging bag. In fact, it is to enter large supermarkets. Because there are regulations in large supermarkets, if the shelf life exceeds one third of the total, goods cannot be received, more than one-half must be cleared, and more than two-thirds must be returned
