Abstract
Abstract An inner laminated foil wrapper 38 of a flip-top cigarette pack has fully sealed flap folds and seams to retain the moisture and aroma of the cigarettes. An opening flap 49 defined by a tear line 52 on the adjoining top and upper front surfaces of the wrapper has a finger tab 47 on its lower edge, overlying the cut-out front wall 35 of an upstanding collar 32, to facilitate opening the pack when the lid 21 is hinged back. The finger tab is formed by an adhesively sealed overlap of the wrapper foil.
