The procedure of the invention makes it possible to offer agri-food industries a simplification, of the. packaging production line by offering them packaging that is ergonomie, light anti hermetic for food products and, in particular, fresh foods, while guaranteeing them a good state «I preservation furthermore, this packaging offers the consumer the option of opening the tray by remot ing the cap easily thank* to the grip offne frame, while retaining the possibility of re-closing it in an airtight manner for storing the product.
