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 said 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.
Claims24
A method for packaging products comprising:
- producing a tray, the method of producing the tray comprising:
- producing a support cut in a forming area of a base film, the base film being a material of a plant or a cellulosic origin;
- obtaining a plastic film having a forming area;
- applying a pressure on the forming area of the plastic film;
- applying a pressure on the forming area of base film, the pressure applied to the forming area of the base film causing a separation of first and second regions of the base film on opposite sides of the support cut such that a gap exists between the first and second regions;
- and
- bonding the plastic film to the base film to form a cavity and a rim surrounding the cavity, the formation of the gap in the base film resulting in the cavity having a first surface area greater than the forming area of the base film.
A machine for packaging products, the machine comprising:
- a pre-cutting tool configured to produce a support cut in a forming area of a base film of a material of a plant or a cellulosic origin;
- a first forming apparatus that is configured to apply pressure on the forming area of the base film, the applied pressure configured to cause a separation of a first region and a second region of the base film located on opposite sides of the support cut to cause a formation of a gap in the forming area of the base film;
- a second forming apparatus that is configured to apply heat and pressure on a forming area of a plastic film, to bond the forming area of the plastic film to the forming area of the base film while at the same time forming a tray having a cavity and a rim surrounding the cavity, the formation of the gap in the forming area of the base film resulting in a surface area of the cavity of the tray to be greater than the forming area of the base film.
