METHOD OF HEAT-SEALING ADHESIVE BANDAGE AND ADHESIVE BANDAGE MADE BY USING SAID METHOD

摘要

Object: to improve adhesive power to the skin without impairing excellent gas permeability and water vapor permeability when a laminate film comprising a film, a fiber fabric and an adhesive layer is sealed by heating at the same time in order to prevent an invasion of liquid from a side of the adhesive bandage. Means, in an adhesive bandage comprising a base sheet made by laminating a film on a thermoplastic fiber fabric and an adhesive layer set on a surface of the thermoplastic fiber fabric of the base sheet, the adhesive bandage is pattern-sealed. The heat seal is preferably performed under the condition that the film does not melt but the thermoplastic fiber fabric melts, and only the periphery of the adhesive bandage may be pattern-sealed.
