This is a four bay bench top tray sealer made in Italy and bought through Contour Packaging in Tauranga.. One of the bays is not currently working - something to do with the heating element.
The tray sealer is fitted with an automatic cutter so that the lidding film is nicely cut around each tray - perimeter cut. It is a semi-automatic model. This means that you put the loaded food trays into the bays, push the bays into the machine and push a button to have them sealed and cut. You pull the bay holder back out, take off the excess film that was cut off and take the food trays out.
I have three boxes of white CPET trays to go with it (about 3,000 trays). These are made in Israel by MCP and distributed in New Zealand. CPET as you probably know is the creme de la creme of packaging trays. They can be used from -40 to +220 deg C so go from freezer to oven.
The tray size is:
Length:137 mm
Width: 94 mm
Height: 35 mm
Volume: 260 ml
The unit is tooled for this size tray and I don't think it can easily be retooled but I am not an engineer!
It was used in my commercial kitchen which has since closed down. The unit has been stored in clean and dry conditions and I have used it recently to seal some meals for my dad in hospital so I know it still performs well.
Even if this tray size is not exactly what you are after this unit and the trays would be great for product development.
I'm more than happy to demonstrate it to anyone seriously interested in making an offer.
