Document Type and Number:
WIPO Patent Application WO/2011/004156
Kind Code:
A3
Abstract:
A packaging wrapper (14) is made of material (48) having inner (50) and outer (52) laminate structures bonded together. A peelable flap (24) is defined in the wrapper by means of offset score lines (54, 56) in the laminate structures, the structures being bonded together in a marginal region between the score lines by means of a peelable adhesive (60). In one aspect of the invention, the score lines (54, 56) are formed using a pair of contra-rotating die cylinders (80, 82, Fig. 8) positioned on opposite sides of the laminated film. Each cylinder contacts a respective laminate structure and has a blade (86, 88) for forming a score line in that structure. In another aspect, the laminate structures (50, 52) are bonded together using a single peelable adhesive (60) both within and outside of the marginal region. In a further aspect, the structures (50, 52) are not bonded together in at least part of the marginal region to provide a lifting tab (46) for the flap.
