A process for producing a thermoformed package comprises the steps of placing a first sheet of film over a forming die having at least one cavity, heating the film to mould the film into the at least one cavity thereby forming at least one recess in the film, placing a composition in the at least one formed recess, and sealing a second sheet of film across the at least one formed recess to produce at least one closed package. Once formed, the or each recess is substantially retained in its formed orientation by the application of a vacuum through the or each cavity.
La présente invention concerne un processus de production d'emballages thermoformés, qui consiste à: placer une première feuille d'un film sur un moule possédant au moins une cavité, chauffer ce film de façon à le faire fondre dans cette ou ces cavités, formant au moins un enfoncement dans ledit film, placer une composition dans ce ou ces enfoncements moulés, et coller une seconde feuille de film en travers de cet ou de ces enfoncements moulés afin de produire au moins un emballage fermé. Une fois moulé, cet enfoncement ou chacun de ces enfoncements est sensiblement maintenu en forme par l'application d'une aspiration à travers la cavité ou chacune des cavités.
