History of vacuum packaging development
Aug 27, 2018

Vacuum packaging technology originated in the 1940s. Since the plastic film was successfully applied to commodity packaging in the 1950s, vacuum packaging technology has developed rapidly. The level of packaging reflects to a certain extent the level of science and technology and the level of affluence in a country. The research and application of vacuum packaging technology in China is still in its infancy.

1. In 1962, Ordal proposed that an oxygen-impermeable membrane can inhibit the growth of pathogenic microorganisms, and packaging fresh meat can prolong its shelf life.

2, Baltzer believes that the fresh-packed fresh meat has a longer shelf life than the aerobic packaged fresh meat:

(1) The total number of microorganisms increases slowly under anaerobic conditions;

(2) Decay and mucus reduction;

(3) After storage, the number of final microorganisms in the vacuum package is less than that of aerobic packaging. This shows that the oxygen-free membrane vacuum-packages the fresh meat. When the oxygen is converted into carbon dioxide, the oxygen-impermeable membrane can block the outside oxygen and enter the package, so the vacuum packaging can prolong the shelf life of the fresh meat.

3. In 1970, Pierson et al. proposed vacuum packaging to create an “ecosystem” that selects the type and level of microbes. In 1974, SCOPA first applied MAP (Modified AtmospherePackage, which is a vacuum first, then a certain percentage). The packaging of the mixed gas) packaged meat products.

4. Pesis et al. (1986) proposed that vacuum packaging is the best preservation method for maintaining the quality and hardness of persimmon fruit. It can be seen that the development and popularization of storage and preservation technology are increasingly valued by producers, operators and consumers.

Another part of the equipment required for vacuum packaging is the packaging container. There are many types of packaging containers. There are composite materials such as plastic, plastic and paper, aluminum foil and other composite materials, glass bottles, metal containers and hard plastics. It should be determined according to the nature of vacuum-packed foods. For canned foods, glass bottles or metal cans are used. For example, Chinese medicines are made of aluminum foil or plastic. Although vacuum-packed containers are of a variety of materials, the most common is plastic film.
