Method of laminating a tubular film , preferably produced by means of blown film (co)-extrusion, with a material which is absorbent with respect to resin or liquids, wherein the tubular film is laminated over its entire circumference with a plurality of layers (10, 11, 12, 13; 20, 21, 22; 30, 31) which overlap or are directly opposite one another at their end faces and which contain absorbent material with respect to resin or liquids so that there are essentially no longer any regions along the circumference of the tubular film which are uncovered by the laminated layers (10, 11, 12, 13; 20, 21, 22; 30, 31), characterised by the following method steps: a) the tubular film is first laminated in a first flat state on its bottom side and/or its upper side with in each case one of the said resin- or liquid-absorbent layers , the lower and upper sides of the tubular film being connected to one another by folded lateral edges of the tubular film , b) the side opposite to said bottom or top side is laminated, if not already done in step a), with a said resin or liquid absorbent layer , c) the flat tubular film is brought into a second flat state by rotation or by rolling through an angle, preferably through an angle of 90°, in such a way that the two said edges on the now flat sides of the tubular film lie opposite one another in alignment with or offset from one another, d) the tubular film is laminated in said second flat state on its lower and/or upper side with a respective said resin- or liquid-absorbent layer , so that the layers partially overlap with the layers , and e) the side opposite to said bottom or top side in said second flat state is laminated with a said resin- or liquid-absorbent layer , if not already done in step d), wherein by steps d) and possibly e) a lamination of said edges is also carried out, wherein preferably the width of said resin or liquid absorbent layers laminated in the second flat state is smaller than the width of said resin or liquid absorbent layers laminated in the first flat state. a) the tubular film is first laminated in a first flat state on its bottom side and/or its upper side with in each case one of the said resin- or liquid-absorbent layers , the lower and upper sides of the tubular film being connected to one another by folded lateral edges of the tubular film , b) the side opposite to said bottom or top side is laminated, if not already done in step a), with a said resin or liquid absorbent layer , c) the flat tubular film is brought into a second flat state by rotation or by rolling through an angle, preferably through an angle of 90°, in such a way that the two said edges on the now flat sides of the tubular film lie opposite one another in alignment with or offset from one another, d) the tubular film is laminated in said second flat state on its lower and/or upper side with a respective said resin- or liquid-absorbent layer , so that the layers partially overlap with the layers , and e) the side opposite to said bottom or top side in said second flat state is laminated with a said resin- or liquid-absorbent layer , if not already done in step d), wherein by steps d) and possibly e) a lamination of said edges is also carried out, wherein preferably the width of said resin or liquid absorbent layers laminated in the second flat state is smaller than the width of said resin or liquid absorbent layers laminated in the first flat state. <EOS>
