Title: LAMINATED MATERIAL FOR PACKAGING AND PROCESS FOR ITS MANUFACTURE
Abstract:
Laminate material (16) comprising a first layer (1) joined to at least one second layer (2) through at least one adhesive layer (3) disposed between these layers (1, 2), wherein at least one first tongue-shaped incision (4) is made in the first layer (1), so as to form in the first layer (1) a tongue-shaped portion (la) that can be separated from the second layer (2) by keeping joined to the second layer (2) the remaining portion (lb) of the first layer (1), a portion (lc) of the first layer (1) which is not in contact with the adhesive layer (3) being disposed around at least one portion of the first incision (4) of the first layer (1), wherein at least one second tongue-shaped incision (7) is made in the second layer (2), so as to form in the second layer (2) a tongue-shaped portion (2a) which can be separated from the second layer (2) by keeping joined to the first layer (1) the remaining portion (2b) of the second layer (2), the second incision (7) being surrounded at least partially by the first incision (4), wherein the second incision (7) has at least one interruption (9). The present description also relates to a process for manufacturing such a laminated material.
