Vacuum packaging, deoxidizing packaging, and retort packaging are three common food packagings. The applications, commonalities, and differences of the three packagings are as follows.
- Applications
Vacuum packaging
The advantages of #vacuumpackaging are: easy to carry, not easy to break, and extend the shelf life of the contents. The air in the package is almost completely exhausted during use because:
- Reduce the volume of the packaged object. In this way, the package can be easily moved against the package, and the impact on the package can be effectively avoided;
- Extend the shelf life of the contents. The reproduction of common bacteria and anaerobic bacteria is suppressed by preventing oxidation of the contents.
Deoxidized packaging
#Deoxygenationpackaging does not require all the air in the package to be removed because:
- Place a deoxidizer in the package to deplete the oxygen in the package;
- Extend the shelf life of the contents. By inhibiting the growth of bacteria, the packaged material is protected from oxidative deterioration.
Retort packaging
The #retortpackaging is a plastic flexible package for high temperature cooking or boiled sterilization. A vacuum is required for packaging because:
- Meet the requirements of cooking or boiled sterilization;
- Prevent the bag from expanding due to heat and breaking the bag.
- Similarities and differences
Commonalities: The common point of vacuum packaging, deoxidizing packaging, and cooking packaging is that they must be made of plastic film with good gas barrier properties.
- Vacuum packaging and deoxidizing packaging only need to use a film with good gas barrier properties and good oxygen barrier properties;
- The retort packaging requires high heat resistance (printing inks and composite adhesives, and also requires good high temperature resistance), and a film with good barrier properties and good water vapor permeability.
Difference:
- Vacuum packaging does not require heating and cooking. However, the retort packaging must first be vacuumed;
- Oxygen may remain in the vacuum package, but the deoxidized package will eventually deplete the oxygen in the package.
