Vacuum packaging history
Nov 07, 2017

Vacuum packaging technology originated in 40s. Since the successful application of plastic film in commodity packaging in 50s, vacuum packaging technology has been developed rapidly. The level of packaging reflects the level of science and technology and affluence of a country to a certain extent. The research and application of vacuum packaging technology in China is still in its infancy.

In 1962 and January, Ordal proposed that impermeable membranes could inhibit the growth of pathogenic microorganisms, and packaging fresh meat could extend shelf life.

Two, Baltzer believes that vacuum packed fresh meat has a longer shelf life than aerobic packaged fresh meat:

(1) the total number of microorganisms increased slowly under anaerobic conditions;

(2) decay and mucus decrease;

(3) after storage, the final amount of microorganisms in vacuum packaging is less than that in aerobic packaging. This shows that the vacuum membrane packaging fresh meat, when the oxygen into carbon dioxide, oxygen barrier film can block the outside of the oxygen and then into the packaging, so vacuum packaging can extend the shelf life of fresh meat.

Three, 1970, Pierson proposed to create a vacuum packaging on the microbial species and level selection "ecosystem" in.1974 SCOPA MAP (ModifiedAtmospherePackage, is the first application of a vacuum first, mixed gas and then filled with a certain proportion of the packaged meat products packaging).

Four, Pesis et al. (1986) suggested that vacuum packaging is the best preservation method to maintain the quality and hardness of persimmon fruit. Thus, the development and popularization of storage technology are increasingly valued by producers, operators and consumers.

Another part of the vacuum packaging equipment required is many kinds of packaging containers, packaging containers, is composed of plastic, paper and plastic, aluminum foil composite materials such as composite, glass bottles, metal containers and hard plastics, selection of packaging containers should be based on the properties of vacuum packaged foods such as canned food is to be, application of glass bottles or cans, such as Chinese herbal medicine with aluminum foil or plastic etc.. Although there are many kinds of vacuum packed containers, plastic film is the most common one.
