The present invention discloses a reclosable pack (1) of smoking articles, said pack comprising a sealed enclosure having a front wall, a back wall, two side walls (7), a top-end wall (8) and a bottom-end wall (6), said enclosure comprising a flexible packaging laminate around a bundle of smoking articles (2), the laminate comprising a built-in easy-opening access, said laminate comprising a permanently tacky adhesive layer (3) sandwiched between an inner layer structure (9) and an outer layer structure (12) comprising an outer score line (13) formed through the thickness of the outer layer structure (12) and an inner score line (14) formed through the thickness of the inner layer structure (9), both delimiting separable opening portions, in which a region of the outer opening portion between the outer and inner score lines (13, 14) is attached to an underlying surface of the inner layer structure (9) via a permanently tacky adhesive (3), the outer opening portion being peelable from the underlying surface of the inner layer structure (9) to build an opening flap (4), and the outer opening portion being re-attachable to the underlying surface of the inner layer structure (9) via said permanently tacky adhesive (3) for reclosing, in use, the opening access, wherein said opening access is exclusively located at the top-end wall (8) of the sealed enclosure.
A reclosable pack of smoking articles, said pack comprising a sealed enclosure having a front wall, a back wall, two side walls, a top-end wall and a bottom-end wall, said enclosure comprising a flexible packaging laminate around a bundle of smoking articles, the laminate comprising a built-in easy-opening access, said laminate consisting of an inner and outer layer structures laminated to one another face-to-face via a layer of a permanent adhesive extending over an entirety of a region between said outer and inner layer structures which is bound by outer peripheral edges of the inner and outer layer structures, further comprising a permanently tacky adhesive layer sandwiched between the inner layer structure and the outer layer structure, said structures comprising an outer score line formed through the thickness of the outer layer structure and an inner score line formed through the thickness of the inner layer structure, both delimiting separable opening portions, in which a region of the outer opening portion between the outer and inner score lines is attached to an underlying surface of the inner layer structure via a permanently tacky adhesive, the permanently tacky adhesive layer is patterned and located on the surface delimited by the outer score line and the inner score line, the outer opening portion being peelable from the underlying surface of the inner layer structure to build an opening flap, and the outer opening portion being re-attachable to the underlying surface of the inner structure via said permanently tacky adhesive for reclosing, in use, the opening access, wherein said opening access is exclusively located at the top-end wall of the sealed enclosure.
