ABSTRACT:
A packaging machine for packaging different products with heat-shrinking plastic film (13) comprises means for cutting and sealing the film and a tunnel to cause the sealed film wrap applied to the product to be packaged to undergo heat-shrinking. Said cutting/sealing means are installed between a first conveyor means for product entry and a second conveyor means which receives said product. Said heat-shrinking tunnel is positioned under said first conveyor means and through said tunnel a third conveyor means is installed for driving the packaged product to exit the packaging machine. Said second conveyor means can be vertically moved from a first, raised position in which said second conveyor means is co-planar with the first conveyor means to a second, lowered position, in which said third conveyor means (17) is co-planar with the third conveyor means.
