Double Chamber Vacuum Packaging Machines

Vacuum packing or vacuum packaging is a method of packaging that removes air from the package prior to sealing. It can involve both rigid and flexible types of packaging. The intent is usually to remove oxygen from the container to extend the shelf life of foods and, with flexible package forms, to reduce the volume of the contents and package

  • Vacuum Packaging Machines require the entire product to be placed within the machine. Like external sealers, a plastic bag is typically used for packaging.
  • Once the product is placed in the vacuum packaging machine with the opening of the bag outside of the vacuum packaging machine, the lid is closed and air is removed, causing the air in the plastic bag to expand.
  • Then, the vacuum packaging machine is refilled with air by the automatic opening of a vent to the outside. This oncoming pressure squeezes all remaining air out of the bag, through the lips of the seal and into the outside.
  • The bag is then sealed. The lid is then opened and the product removed. vacuum pacakaging machines are typically used for higher-volume packaging, and also have the capability to vacuum seal liquids

Application :

It is also commonly used to store of dry foods over a long period of time, foods such as cereals, nuts, cured meats, cheese, smoked fish, coffee, and potato chips (crisps). On a more short term basis, vacuum packing can also be used to store fresh foods, such as vegetables, meats, and liquids, because they inhibit bacterial growth.
