SEE VIDEO BELOW

These systems come with Micro Knife Impulse sealing technology that uses a teflon coated single piece band ribbon located in upper seal bar. It will seal PVC or polyolefin films without smoke or residue. They offer extra wide loading tables to make inserting materials into the shrink film easy. The heat-shrinking tunnel is designed to achieve the maximum results with the lowest use of electricity. Heat-shrinking operation is adjusted by setting the tunnel temperature and speed and can work with all types of heat-shrinking films.

These systems come in both manual or pneumatic versions that require air compressors. The semi automatic pneumatic systems allow the operator to feed the machine while the sealing bar goes up and down as programmed, i.e. every 2 or 3 seconds. The unit can also operate with a push button control to activate the sealing bar.
