Many foods now use vacuum packaging for long-term storage, which can prevent food from oxidizing and maintain the original 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 not to eat it, because the vacuum packaging is to prevent the ingress of air and prevent oxidation to prevent decay. If the vacuum packaging leaks, it proves that the air has entered, so the items may have deteriorated.


The leakage of vacuum packaging bags should be considered from the following two aspects:

1. Product: Whether the shape is regular and whether there are raised parts, it is easy to puncture the bag or puncture the air leak;

2. Bag: What is the quality of the bag? Is the thickness of the bag appropriate? Is the size of the bag appropriate? Is the size of the outer box appropriate?


Professionals also emphasize that if the contents have corners, friction during transportation, the bag is too thin, and the bag is too thick (causing insufficient sealing quality), it will cause air leakage! There are two reasons:


1. The bag is too thin. When the vacuum is excessive, the bag will stretch and deform in the protruding part of the product, and serious pinholes will appear.

2. When sealing the bag, pay attention to keep it flat and prevent it from being discounted, because pinholes also appear at the discounted place. It may be handled by appropriately increasing the heat-sealing temperature or lengthening the heat-sealing time, but it cannot be completely avoided. Therefore, when packing food, you should choose a good quality vacuum packaging bag, such as Sausage Casing.

How about vacuum packaging? Vacuum packaging, also called decompression packaging, is to extract all the air from the packaging container and keep it in a highly decompressed state. The scarcity of air is equivalent to the effect of hypoxia, so that microorganisms have no living conditions to achieve fresh fruit and no disease. What happened. At present, vacuum packaging in plastic bags, aluminum foil packaging, glassware, plastics and composite packaging are used. Sausages are also vacuum-packed. Reliance on sausage sealers to vacuum-pack sausages with Aluminum Clip can extend the shelf life of food to a limited extent. Packaging materials can be selected according to the type of article. Because fruits are fresh foods, they are still breathing, and high levels of hypoxia can cause physiological diseases. Therefore, vacuum packaging of fruits is less common.


In the field of people's life and work, a variety of plastic vacuum packaging abound. Lightweight, sealed, fresh-keeping, anti-corrosion, and rust-proof plastic vacuum packaging covers a wide range of fields from food to pharmaceuticals, knitwear, from precision product manufacturing to metal processing plants and laboratories. The increasing application of plastic vacuum packaging has promoted the development of plastic vacuum packaging machines and has also put forward higher requirements on them.


Vacuum packaging must be quick frozen at -40 ° C, and then stored at -18 ° C for about three months. If preservatives are added to deli products, they can generally be stored for 15 days using vacuum packaging, and can be stored for 30 days if they are stored at low temperature, but if no preservatives are added, they can only be stored for 3 days in vacuum packaging even at low temperature. After days, both the taste and taste will be much worse. Some products will write a retention period of 45 days or even 60 days on the packaging bag. In fact, that is to enter a large supermarket. Because large supermarkets have regulations, the shelf life of more than one-third of the total can not be received, more than one-half will be cleared, more than two-thirds will be returned.
