PURPOSE:To provide a self-adhesive film improved in releasability so as riot to generate blocking even if the film is formed into a roll shape, capable of being simply wound around a grafting part in a state stretched by 2-10 times, capable of keeping a wound state by self-adhesiveness and capable of keeping the rooting rate of grafting high. CONSTITUTION:A soft film with a thickness of about 50-200mum having self- adhesiveness is molded and a fine powder with an average particle size of 1-60mum such as an inorg. powder, a plastic powder or a starch powder is scattered over the film to be bonded thereto in an amt. of about 0.5-10g/m<2>. Releasability is kept by the fine powder and, by winding this film in a state stretched by 2-10 times, self-adhesiveness is developed. |
