Abstract: A package (1) of the two-material box type for packaging a product, advantageously a foodstuff, includes an outer envelope (2) which is made up of two envelope parts (5, 6) connected by hinge-forming elements (10) for moving them between—a closed position, so as to jointly define a closed storage volume (1?) intended to contain the product, and—an open position so as to allow access to the storage volume (1?), the two envelope parts (5, 6) being internally covered by one and the same sealed one-piece plastics film (3). The two envelope parts (5, 6) are made up of two separate parts; and the sealed plastics film (3) has an interposed strip (10), extending between the two separate envelope parts (5, 6), so as to form the hinge elements.

Abstract: Apparatus for making a pack tray includes a body with a strip of side walls, the body including an outer envelope lined on the inside with an added sealed plastic film. The apparatus includes at least one station provided with elements for applying glue on a portion at least of the inner surface of the side wall strip of the outer envelope, also called gluing area, before placing a plastic film. The gluing pads include at least one block of a porous material that can, one the one hand, be filled with glue by loading members through a diffusion phenomenon, and that can deposit glue by contact optionally combined with a compression force on the gluing area. The pad is mounted on a bearing structure via members for handling it between expanded positions in which the pad contacts the gluing area for applying glue thereon and a folded position in which the gluing pad is remote from the outer envelope of the pack tray.
