Title: Process for producing hinge-lid boxes for cigarettes

Abstract: Process for producing packs made of thin cardboard with an outer wrapper made of shrink-wrap film. Folding tabs of the outer wrapper are connected to one another by full-surface-area heat sealing. The shrink-wrapping process for the outer wrapper may be initiated as a result. In order to ensure a correct form of the outer wrapper, the folding tabs, prior to the full-surface-area sealing operation, are connected to one another by a tack seal, with small, limited sealing surface areas, and are then sealed over the full surface area.
