Abstract
A medical adhesive dressing comprising a polyolefin-based backing film having a medical pressure-sensitive adhesive layer on one surface thereof and a print layer on the other surface thereof, the adhesive dressing having surface properties that cause no wrinkle upon winding and unwinding thereof. For example, the surface of the polyolefin-based film preferably has a surface roughness (10-point average roughness) of 2 to 12 &mgr;m on the side where a print layer is to be formed. The olefin-based film is preferably an ethylene-vinyl acetate copolymer film or a three-layer film comprising an ethylene-methyl methacrylate copolymer layer/A-B-A type block copolymer layer/ethylene methyl methacrylate copolymer layer. It is used for application to skin as a first-aid adhesive tape, large-size adhesive tape, dressing, or draping used in the field of medical and hygiene fields. It can provide medical adhesive dressing and first-aid adhesive tape whose surface causes no printing failure.
