subject: Medical Kinesio Tape Or Sheet, And First-aid Kinesio Tape [print this page] . A medical kinesio tape for adhering onto a skin surface comprising a supporting substrate and an adhesive layer directly or indirectly laminated thereon, wherein said supporting substrate comprises a composition which comprises 100 parts by weight of a thermoplastic resin and 10 to 200 parts by weight of a silicic acid compound, wherein said medical kinesio tape is adhereable to a skin surface, and wherein said supporting substrate has a stress relaxation ratio of 60% or less.
Conventionally, many films comprising a plasticized polyvinyl chloride as a main component prepared by a calender method or a sol cast method have been used as various medical kinesio tapes or sheets such as a first-aid kinesio tape or a surgical tape.
A film for a supporting substrate comprising this plasticized polyvinyl chloride as a main component has the characteristic that it shows high stress at a tensile initial stage, but stress relaxation rapidly occurs with the passage of time. This stress relaxation is due to plasticity of the polyvinyl chloride film. In the case where a kinesio tape or sheet that includes a film for a supporting substrate having such a characteristic is adhered to a skin, tensile stress is gradually relaxed after the adhering, resulting in a reduction of load to the skin. Thus, with use of the supporting substrate film comprising the plasticized polyvinyl chloride as a main component, adhering workability is secured by an appropriate stress when adhering, and also a tense feeling is eliminated by the subsequent stress relaxation, so that physical irritation to the skin is alleviated. This imparts the tape or sheet with both good operability and low skin-irritating property.
