STRETCH MULTIPACK for overpack unit packaging.
MULTIPACK STRETCH FILM: HOW IT WORKS
Packaging unit is pushed through the curtain film system of the machine.
Pushing system, film’s stretching units and lateral welding are operated by a servomotor and can work synchronously in a very specific set report. In this way we can get packaging stretching without having later to go through a shrink tunnel.
Pushing system moves packaging trough the curtain film.
During the whole operation, stretching units continuously stretch the packaging film depending on the introduction and on the lateral welding.
Lateral welding includes preheated flat welding system associated with mechanical cutting.
Welding and cooling time are electronically operated.
