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.

Abstract: A package (10) is formed from a flexible laminated wrapper (14) having an outer laminate structure (26) and an inner laminate structure (24) and includes a tear strip (30) formed in the wrapper. The tear strip has an outer tear strip portion (40) defined between a pair of outer spaced lines of weakness (42, 44) in the outer laminate structure. At least one inner line of weakness (48, 50) is formed in the inner laminate structure offset from the outer lines of weakness. At least a part (54) of the tear strip defined in one of the outer and inner laminate structures is bonded to an overlapping region of the other of the outer and inner laminate structures in a peelable manner. An inner tear strip portion (46) may be defined in the inner laminate structure (24) between a pair of spaced inner lines of weakness (48, 50).

Abstract: Packaging for a generally block shaped product (12) is made from a wrapper (14) of flexible material encasing the product. The wrapper has a foldable flap portion (24) adjacent an end of the package. The free edges (28, 30, 32) of the flap over-lap a further portion (34) of the wrapper and are bonded by means of a peelable and re- sealable adhesive (37). The flap (24) extends fully across one face (38) of the package and at least partially down opposing sides to form a sealed and re-sealable closure for the package. The package can be formed using flow-wrap techniques and is particular suited for packaging chocolate bars and the like.

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.

Abstract: 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.

Abstract: Packaging particularly for display on a Euro-hook or the like comprises a bag or pouch (10) closed at one end by means of a header (14). A line of weakness (18) extends across the header dividing it into an outer portion (14A) and an inner portion (14B) both of which are sealed. An aperture (16) is provided in the outer portion (14B) of the header for suspending the packaging for display purposes. The outer portion (14A) can be separated from the inner portion after removal from the display hook by tearing along the line of weakness. The seal in the inner portion (14B) of the header is peelable to allow for ease of opening. A method of manufacturing the package and an apparatus (30) for forming the packaging are also disclosed. The apparatus includes a pair of cross jaws (32) having a punch for forming the aperture and at least one knife guide.
