What is the Principle of Vacuum Packaging Machine?

Vacuum packaging machine uses the principle of vacuum packaging. Vacuum packaging is also called decompression packaging, which is to extract and seal all the air in the packaging container to maintain a high degree of decompression in the bag.

The scarcity of air is equivalent to the effect of low oxygen, so that microorganisms have no living conditions, so as to achieve freshness and no disease.

What is the application range of vacuum packaging machine?

Including plastic bag vacuum packaging, aluminum foil packaging, glassware, plastic and its composite packaging, etc.

Packaging materials can be selected according to the type of item. Since fruits are fresh food and are still undergoing respiration, a high degree of hypoxia can cause physiological diseases. Therefore, less fruit is vacuum-packed.

What are the advantages of vacuum packaging machines?

1. Anti-corruption

Part of the air (oxygen) in the packaging container is eliminated, which can effectively prevent food spoilage.

2. Keep it fresh

The use of packaging materials with excellent barrier properties (air tightness) and strict sealing technology and requirements can effectively prevent the exchange of packaging contents, and can avoid food weight loss, loss of taste and secondary pollution.

3. Sterilization

The gas inside the vacuum packaging machine has been excluded, which accelerates heat transfer, can improve the efficiency of thermal sterilization, and can also avoid the packaging container from breaking due to gas expansion during thermal sterilization.
