Abstract: Provided is a method and machine for packaging products, whereby a tray is generated by means of bonding a plastic film to a base film, the tray including a cavity of a given area and a rim surrounding the cavity. The cavity is generated by applying a given pressure on a forming area of the films. Before generating the tray and before pressing the base film, a support cut is generated in the forming area of the base film, such that with the subsequent pressure on the base film at least one gap is formed in the cavity of the tray as a result the support cut.

Abstract: According to one embodiment a packaging machine and method for packaging a product is provided in which a cover film is arranged on the product and on a base film which supports the product and is narrower than the cover film; the superimposed films are moved in a first direction to a joining station where both films are attached to one another; and the attached films are moved in the first direction to a cutting station where the films are cut transversely and where the areas of the cover film projecting from the base film are cut longitudinally. The movement of the films is caused by acting on the cover film.

Abstract: A modified atmosphere, skin or vacuum packaging machine comprising first feed means adapted for feeding a first film to the machine, second feed means adapted for feeding a second film to the machine, and a sealing station where the vacuum is formed and/or the modified atmosphere is introduced, and the second film is sealed to the first film to obtain a package. The machine comprises displacement means configured for moving at least the first film a driving distance from an initial position, holding down and driving at least the first film in the driving direction to an end position, said displacement means being configured for subsequently returning to the initial position when the machine is in operating mode.

Abstract: A skin packaging machine in which a first continuous film and a second continuous and thermoplastic film above the first film are supplied in a forward direction of the machine. The machine includes a sealing station configured for receiving both films, and it comprises an upper tool pressing on the films to seal them to one another, with a closed holding contour delimiting the area of said films being sealed. The sealing station further comprises a sealing gasket attached to the holding contour, the sealing gasket having, on each side with respect to the forward direction, an operation zone with a notched configuration which is facing the space delimited by said sealing gasket.

Abstract: A packaging machine having a sealing member that acts on a product wrapped by a lower film and an upper film, and which seals or closes the films to each other around the product in order to vacuum-package said product between both films, and control means for causing the sealing member to move in order to package the product. The sealing member defines at least one inner space where the product to be vacuum-packaged is disposed wrapped at least partially by the two films. According to one implementation the sealing member includes at least one longitudinal first wall, a longitudinal second wall and a transverse wall between which the inner space is defined, and an unobstructed opening facing the transverse wall.
