    • A transdermal patch which comprises: a substrate sheet comprises a composite film formed of a resin composition comprising 100 parts by weight of a polyvinyl chloride-polyurethane composite and 2-10 parts by weight of a styrene-ethylene-butylene-styrene copolymer, a first adhesive layer on the one side of the composite film, and a polyalkylene terephthalate film adhered to the one side of the composite film by means of the first adhesive layer, a primer layer which comprises a saturated polyester resin and is formed on the surface of the polyalkylene terephthalate film; and a second adhesive layer comprising a styrene-diene-styrene block copolymer containing a pharmaceutical agent layered on the primer layer. A method for the manufacture of the above-mentioned substrate sheet comprises preparing the above resin composition molding the resin composition into a composite film by a calendar process, and then adhering a polyalkylene terephthalate film on one side of the composite film by means of an adhesive layer thereby forming the substrate sheet, and forming a primer layer comprising a saturated polyester resin on the outer surface of the polyalkylene terephthalate film.

    • Packaged patch (10) according to the invention comprises patch (2) situated in space (4) inside patch package (3) composed of laminated packaging material (1), and its edges are sealed. Laminated packaging material (1) comprises hygroscopic material layer (13) made of LDPE containing 20–40 wt % of an inorganic filler, situated between moisture-permeable material layer (14) made of LDPE and having a moisture permeability of 40–120 g/m2/day and a screen material layer which blocks penetration of moisture, etc. and is composed of HDPE layer (12) and aluminum foil (11). The saturation hygroscopicity of laminated packaging material (1) is 2–30 g/m2 under atmosphere conditions with a temperature of 25° C. and a relative humidity of 75%. This construction sufficiently reduces the effect of moisture on a drug in patch (2) and allows patch (2) to be held in a stable state for prolonged periods, while also improving the economy and handleability of patch package (3).
    • 根据本发明的包装贴片(10)包括位于由层压包装材料(1)组成的贴片包装(3)内的空间(4)中的贴片(2),并且其边缘被密封。 层压包装材料(1)包括由含有20-40重量%无机填料的LDPE制成的吸湿材料层(13),其位于由LDPE制成的透湿材料层(14)之间,具有40-120g的透湿性 /天/天,以及阻挡水分渗透等的屏幕材料层,并且由HDPE层(12)和铝箔(11)组成。 层压包装材料(1)的饱和吸湿性在25℃,相对湿度为75%的气氛条件下为2-30g / m 2。 这种结构充分降低了水分对斑块(2)中药物的影响,并使斑块(2)长时间保持在稳定状态,同时也提高了贴片包装(3)的经济性和可操作性。
