770 & 770VG – Full Automatic Food Sealer

MODEL 770 & 770VG – AUTOMATIC THERMO-WELDER BY OUTLINED FILM CUT

Model 770 is a heat sealer particularly suited to large-sized outputs. The 778VG version allows for getting vacumm or vacuum-gas ( modified atmosphere, M.A.P.system – Modified Atmosphere Packaging ) sealed tubs.

WHAT DOES IT MANUFACTURE?

The machine can thermo-weld appropriate portion of film over tubs containing convenience and pre-cooked food (solid, liquid, creamy, pasty), generic foodstuff and non-food items too. The film is accurately sealed and cut along the whole extent of the tub’s outline. It is possible to provide for a pull tab for product’s easy opening to any corner or side of the tub.

PERFORMANCE

  • 26/27 tubs/minute by Single Format
  • 53 tubs/minute by Double Format

770VG :

  • 10 tubs/minute by Single Format
  • 20 tubs/minute by Double Format

These are indicative figures as the actual performance reies on the tub material, dimensions, type of content (solid, liquid, creamy, pasty), the compatibility to thermo-welding power between film and container materials…
