Many foods now use vacuum packaging for long-term storage, which may prevent food from oxidizing and maintain the first flavor of the food. Is it safe to leak the vacuum pack? Can the food that leaks out of the vacuum packaging still be eaten?
It is best to not eat it, because the vacuum packaging is to stop the ingress of air and stop oxidation to stop decay. If the vacuum packaging leaks, it proves that the air has entered, therefore the items may have deteriorated.
The leakage of vacuum packaging bags should be considered from the subsequent two safty aspects:
1. Product: Whether the form is regular and whether there are raised parts, it's easy to puncture the bag or puncture the air leak;
2. Bag: what's the standard of the bag? is that the thickness of the bag appropriate? is that the size of the bag appropriate? is that the size of the outer box appropriate?
Professionals also emphasize that if the contents have corners, friction during transportation, the bag is just too thin, and therefore the bag is just too thick (causing insufficient sealing quality), it'll cause air leakage! There are two reasons:
1. The bag is just too thin. When the vacuum is excessive, the bag will stretch and deform within the protruding a part of the merchandise , and high pinholes will appear.
2. When sealing the bag, concentrate to stay it flat and stop it from being discounted, because pinholes also appear at the discounted place. it's going to be handled by appropriately increasing the heat-sealing temperature or lengthening the heat-sealing time, but it can't be completely avoided. Therefore, when packing food, you ought to choose an honest quality vacuum packaging bag, like Sausage Casing.
