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.
Claims18
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;
- simultaneously applying heat and pressure to the forming area of each of the base film and plastic film to simultaneously bond the plastic film to the base film while at the same time 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;
- the bonding of the plastic film to the base film forming 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 forming apparatus that is configured to simultaneously apply pressure and heat on the forming area of the base film and on the forming area of a plastic film disposed over the forming area of the base film, the applied pressure and heat configured to simultaneously cause a bonding of the forming area of the plastic film to the forming area of the base film while at the same time causing 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;
- the applying of heat and pressure on the forming area of the plastic film 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.
