Tray Sealers & Thermoformers

Tray Sealers fall into four main catagories.  There are three that use a preformed tray and can either just seal a film onto the tray or can add a modified atmosphere into the tray. Alternativly a Thermoformer can form the tray from a roll of film which is then loaded and sealed before the machine seperates the finished sealed trays.
