Vacuum packaging is to extract the oxygen in the packaging bag and food cells, so that the microorganisms lose their "living environment", inhibit the reproduction of microorganisms such as bacteria, avoid the oxidation and mildew of the items. And at the same time, some soft items, after being packaged by the automatic vacuum packaging machine, the packaging volume can be reduced, which is convenient for transportation and storage.
The proper vacuum sealer is very important when considering the type of vacuum packaging to accommodate company needs. In this post, we will go over the different kinds of vacuum sealers available. Hopefully, this will help guide you in the right direction.
This form of vacuum sealer commonly uses vacuum bags loaded into a chamber to remove air. Once the air is removed from the vacuum bag, a seal is made to close the open bag end. A chamber vacuum sealer is an excellent option for meat cuts, liquids, cheeses, and a variety of other products.
In vacuum skin packaging, a vacuum chamber is used to press and clamp film together and remove air from the package. Thermoform vacuum skin packing machines are often found in high-speed production facilities.
Two rolls of film are used and clamped together within a vacuum chamber. Once the air is removed from the vacuum chamber, two clamps close and seal the two plastic films.
Another type of vacuum packaging is very similar to vacuum skin packaging. The primary differences between them is that product presentation and packing cost. Thermoform vacuum packer applies a more economic packing material, which skin packer applies a special packing film to achieve a 3D product presentation. So skin packing is more often applied in premium products like meat and seafood.
