A pack for liquids is made at least partially from cardboard or the like, which is impervious to liquid at least on its one surface, by virtue of a plastics coating. The pack has side walls (1-3), a bottom and a top wall (1), which are connected together at least partially by fold (9) and/or sealing seams (4), a tear-open pouring opening (6) which is disposed in the top wall (1) adjacent the edge line (9) and which is preferably covered over by a tear-off cover strip (7) and a pouring edge (8) which is disposed in one plane with the top wall (1). A separate plastics strip (10) is sealed in position in the region of the pouring opening (6), covering over same, and extends beyond the edge line (9) of the top wall (1) with an unsealed end (11), forming a pouring edge (8), and the surface of the plastics strip (10), which covers over the pouring opening (6), is stamped out, exposing the opening (6), and is laid over around the edge (12) of the opening and is sealed in position from the underside.
