Machines with continuous side sealer allowing production of packs with nice appearance.Great flexibility in size change-over to be made with simple adjustments by a hand-wheel. They can be equipped with hot air sealer for PE film or continuous sealer for PP-polyolefine films.

• Continuous side sealer with front traverse sealing through one-fold film.

• Steady sealing temperature, controlled by thermoregulator

• Motor-driven adjustment of transversal sealing level

• Teflon-coated, sealing bar at constant temperature, controlled by thermoregulator

• Motor-driven film unwind

• Tunnel conveyor in steel wire netting (or slats coated with a silicone sheath) equipped with mechanical variable speed gearmotor for adjusting the conveying speed.

• Heat shrink chamber, duly insulated through mineral wool, equipped with suction fan and further uniform recirculation of the air around the pack in a closed circuit. A set of finned heat resistors provides for air heating. Their location allows quick replacement during maintenance. Air can be directed both sideways and towards a central position under the tunnel by means of special baffles according to a variety of problems that can arise during shrinking cycle.

• Tunnel heat regulation by means of thermostat limiting consumption, once the operating temperature is reached.
