For each tray design, a custom mold is created for the machine. All models except TBG Pro and TBG+ Pro allow interchangeable molds. The same mold can be used to package trays of the same design in different heights.
The second step in your tray-sealing project is to determine the desired shelf life for the packaged food. There are different finish types:
This feature is standard on every model in the catalogue.
The machine blasts gas into the tray just before sealing it. This "sweep" of gas reduces the amount of O2 in the packaging, delaying the oxidation of the food. In this type of packaging, a residual percentage of O2 always remains, so the maximum shelf life is not achieved.
In this case, the machine has a system for vacuum packaging + gas injection, achieving the same appearance in the packaged tray as in "only sealing" or with "gas flushing" but with the difference that in this packaging the residual % of O2 is minimal to thus achieve maximum expiration date in the packaged food.
This type of packaging is carried out using machines equipped with a vacuum system. It is a vacuum-sealed packaging without gas injection. Skin packaging requires using a roll of film made of specific skin-seal material so that the machine can heat the plastic and vacuum-seal it to the surface of the product to be packaged.
The same tray skin technology, but applied to a flat sheet. This can be laminated cardboard or sealable plastic backing. The cardboard can be printed with custom designs and images. The maximum height of the product to be packaged is 35 mm.
*Depending on the expiration date required for the food to be packaged, the gas sweep or vacuum + gas injection system in a modified atmosphere will be more advisable.
