Abstract
A packaging apparatus includes a conveyor that moves one or more supports towards a packaging station, while a plastic film to be applied to said one or more supports is simultaneously transported to the packaging station itself. A longitudinally cutting unit longitudinally cuts the plastic film in order to form two or more film strips, and a compensating device exerts a tensioning action on one or more portions of said film strips. A packaging method includes longitudinally cutting the plastic film into strips and compensating to suitably tautly hold the film strips during their movement.
