Abstract
To 100 parts by weight of a thermoplastic resin such as polypropylene resin, a blend of polypropylene resin and elastomer, or a copolymer of polypropylene resin and elastomer, 10 to 200 parts by weight of a silicic acid compound such as zeolite or talc were added to form a film for a supporting substrate. Using this film as a supporting substrate, an adhesive layer comprising an acrylic adhesive is provided on the supporting substrate to obtain a medical adhesive tape or sheet according to the present invention. An absorbent pad is provided at a central region on the surface of the adhesive layer to obtain a first-aid adhesive tape.
