    • PURPOSE:To obtain a bag material for an individually packaged detergent by thinly coating a water-permeable fabric substrate composed of water-insoluble fiber with a liquid water-insoluble resin, drying the coating by heating, forming a resin layer for filling and then coating the aforementioned layer with a liquid water-soluble resin. CONSTITUTION:A water-permeable fabric substrate 22 composed of water-insoluble fiber is withdrawn from a roll 42, thinly coated with a liquid water-insoluble resin for filling so as not lose water permeability with a roller 44, directly passed through a heating zone between a rotating type heat drum 52 equipped with a heat-resistant rubber and a cover 54 and dried by heating to form a resin layer for filling. The resultant substrate is then coated with a liquid water-soluble resin (e.g. a composition of PVA and ethylene vinyl acetate copolymer) with rollers 58 and dried by heating to afford a bag material (sheet) 20. A bag 12 is formed from seals 20 and 30 composed of substrates 22 and 32, resin layers 24 and 34 for filling and water-soluble resin layers 26 and 36. A prescribed amount of a powdery detergent 14 is placed on the aforementioned bag and sealed at sealing parts 16 to provide the objective bag material 10 for the individually packaged detergent used in, e.g. fully automatic washing machines.
