Abstract

A packaging wrapper is made of material having inner and outer laminate structures bonded together. A peelable flap is defined in the wrapper by means of offset score lines in the laminate structures, the structures being bonded together in a marginal region between the score lines by means of a peelable adhesive. In one aspect of the invention, the score lines are formed using a pair of contra-rotating die cylinders positioned on opposite sides of the laminated film Each cylinder contacts a respective laminate structure and has a blade for forming a score line in that structure. In another aspect, the laminate structures are bonded together using a single peelable adhesive both within and outside of the marginal region. In a further aspect, the structures are not bonded together in at least part of the marginal region to provide a lifting tab for the flap.
