PURPOSE:To prevent the scattering or the consumption of a drug, to facilitate the cutting of breaks and to enhance a fixed form property and longitudinal and lateral mechanical strength, by cutting a large number of discontinuous breaks in a multilayer laminate in a zigzag pattern to stretch said laminate in the direction right-angled to the direction of the breaks and laminating two stretched ones to a drug impermeable plastic sheet in a warp-weft state so as to bring said plastic sheet to an outer layer. CONSTITUTION:A sheet 2, which is composed of a resin formed by impregnating a drug impregnating resin such as an ethylene/vinyl acetate copolymer with a drug such as perfume or a resin composition prepared by further diluting the drug impregnated resin with a polyolefinic resin, is delivered and drug impermeable sheets 3, 3' composed of a saponified ethylene/vinyl acetate copolymer are laminated to said sheet 2 and the whole is uniaxially stretched by stretching or rolling rolls 5, 5' and a large number of uncontinuous breaks 9 are cut in the laminate in a zigzag pattern in a flow direction by a fiber dividing jig 6 and the stretched laminate is widened on a belt conveyor 7 in the direction right-angled to the break direction to form a widened body 8. Subsequently, the widened body 8 is appropriately cut and the cut ones are laminated in a warp-weft state to obtain a drug-containing reticulated body 7. |
