AS-4 Plastic Sandwich Box Vacuum Nitrogen Packing Sealing Machines

As-4 Plastic Sanawich Box Vacuum Nitrogen Packing Sealing Machine is vertica

type vacuum and gas-flush pneumatic tray sealing system, vacuums the tray

completely before it inserts gas.The machine is built in stainless steel for use in

hygienic environments.The system is tooled up to your specific tray size and

neatly trims the film around the perimeter of the tray, the wasted film is then

taken up onto the motorized film feeding system. This machine requires a

compressed air connection.

Main Function:

The food trays are manually placed in the tray carrier drawer. As a safety

precaution,the operation is initiated by the two handed release system.

The tray carrier moves automatically into the machine and the machine head

comes down and seals around the tray carrier.

The large capacity vacuum pump efficiently evacuates the chamber and the gas

flush is carried out.

The sealing head then moves down, completing the perimeter seal around the

tray as well as a neat perimeter cut.

The tray carrier drawer then automatically moves back out to the operator and

the trays may be removed.

While removaland reloading ofthe trays takes place, the film is automatically fed

to the newposition.The new position is determined by either time, blank film

counting （to calculate the film length oftray for saving the film cost) or by photocell sensor

mark (for printed film).
