FIELD: packages, particularly miscellaneous auxiliary devices operating on sheets, blanks, webs, binding material, containers, or packages.
SUBSTANCE: double-chamber bag has dispensing means and is produced during form/fill operation. Bag production method involves connecting dispensing means to film, which creates partition between bag chambers; connecting films to dispensing means to form outer bag walls; sealing upper and side edges of the bag to create bag having opened bottom. The bag may be produced of films received from three sources. Outer walls are formed of the first film material or of film web passing from common film source and having W-shaped configuration. The bag preferably is filled through opened bottom end, which is sealed after bag filling. Then the bags are separated one from another by cutting seam connecting the bags to create bag chain comprising predetermined number of bags. The dispensing means may be disposable or resealable.
EFFECT: decreased number of bag production and filling operations and improved sanitary requirements.
