Types of vacuum packaging
The right food packaging can make all the difference when it comes to freshness, cleanliness and overall nutrient preservation.Basically, the better the food is packaged, the better is it for you. The technology and the science behind sealing and packing food under vacuum is the reason why it is a good choice for the packaging of meat, dairy and vegetables etc.
This basic idea of vacuum packing is to remove air from the package prior to sealing. It involves (manually or automatically) placing items in a plastic film package, removing air from inside, and sealing the package. There are a few different ways and types of vacuum packaging methods like shrink wrap, skin wrap and modified atmosphere packaging (MAP).
1.Shrink wrap
In a shrink wrap, vacuum packed products are heated in a water bath to shrink the film before drying for a more tight, compact wrap. In skin wrap, a special film envelops the products without tension like a second skin.
2.Modified atmosphere packaging (MAP)
For modified atmosphere packaging (MAP) processes, well, it’s all in the name. This method involves altering or modifying the atmosphere inside the package. This is done by replacing it with as mixture of CO2, nitrogen or even oxygen in high concentration to inhibit aerobic microorganisms. The result is a protective environment around the food that preserves its taste, safety, and appearance.
