Abstract
A tubular bag with cap closure for the accommodation of fluid foodstuffs, wherein the base of the bag is constructed especially as a standing base and is welded or sealed fluid-tight with the bag as a separate component along the base-end bag edge, wherein the tubular part of the bag is manufactured from a single cut of film, especially a cut of laminated film, the longitudinal edges of which are sealed one over the other to form a “lap seal” (inner/outer seal) or alternatively constructed as a “fin seal” (inner/inner seal). A cap closure that is part of a relatively stiff cover is welded or sealed fluid-tight with the upper or closure-end bag edge. The tubular bag according to the invention has an enhanced filling capacity and improved stability.
