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. 

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. The vacuum sealed sausage shelf life can be very long.


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.

Reasons of leakage

1. Product is too tough

If the shape is irregular and there are raised parts, it is easy to puncture the bag or puncture the air leak;

2. The bag is too thin

If the contents have corners, friction during transportation, the bag is too thin, it will cause air leakage! When the vacuum is excessive, the bag will stretch and deform in the protruding part of the product, and serious pinholes will appear.

3. There are discounted places

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.

Vacuum sealed food shelf life

Vacuum Sealed foods last from anywhere between a few days to a few weeks. Typically, foods last for 1-3 days in the fridge. The shelf life of Vacuum Sealed foods increases and, the food lasts for 1-2 weeks instead.

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 have a shelf life of 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 vacuum sealed food will write a shelf life 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.



The increasing application of plastic vacuum packaging has promoted the development of vacuum packaging machines and has also put forward higher requirements on them. We SHENGMAO have developed a series of products such as clipper machines, Great Wall clips(R-clips), U-shaped clips, wire clips, Used in a variety of emulsion explosives, silicone rubber, meat products, mining anchors, edible mushrooms, fruits, supermarket packaging and other small packages of ligation and sealing.
