<p>Open-mouth bag (4) made of coated or uncoated polyolefin woven fabric, in particular polypropylene or HDPE (high density polyethylene) woven fabric, which forms a substantially tubular main body (23), having a closed first end region (24) and an open second end region (26), or bag (25) closed at two ends, produced from a coated or uncoated, filled open-mouth bag (4) which is closed at one end and is made of polyolefin woven fabric, in particular polypropylene or HDPE woven fabric, having a substantially tubular main body (23). In order to ensure a tight and secure closure and to rule out damage to the main body (23) caused by stitching and possible contamination associated therewith, it is provided that the closed first end region (24) of the open-mouth bag (4) or at least one end region (38) of the bag (25) closed at two ends is formed by a strip-like, coated web of material (14), which has a V-shaped or U-shaped fold in cross section and the legs (27) of which are thermally welded to the tubular main body (23).</p> |
