A method of manufacturing a packaging material comprises laminating together at least two layers of materials to form a laminated packaging material having an inner laminate structure (20) and an outer laminate structure (22), one of which (22) is translucent or transparent and the other (20) opaque. The method includes forming a score line (28) in the opaque laminate structure to define a section (26) within the opaque laminate structure which can be wholly or partially removed. The score line (28) can encircle the section to allow its removal after lamination to form a window (14, FIG. 1) in the packaging. Alternatively, the score line (328, FIG. 7) may only partially encircle the section (326, FIG. 7) such that it remains attached to the remainder of the opaque laminate structure along a line (332, FIG. 5) about which section of opaque laminate structure can be folded in the manner of a flap. |
