Abstract: A film packaging apparatus, operating on a flow of products movable along a feed direction and apt to package each product into a respective wrapping of heat-sensitive film, includes: a transversal sealing unit, having a heat sealer and a sealer receiving element, apt to seal transversal portions of the film transversally to the feed direction, an actuator with mechanical drive element for moving the heat sealer and the sealer receiving element in the direction of the flow; and a control unit, which controls the actuator so that, at a sealing section of the path of the products along which the heat sealer produces the sealing of the transversal portions of film, the speed of the heat sealer element and sealer receiving element in the direction of the flow is constant and equal to the speed of the flow of products.
