ABSTRACT:
An adhesive film for adhesive bandage in which an adhesive is coated on one surface of a nonwoven fabric, characterized in that a film having water vapor permeability and water proofing property is laminated on the opposite surface of the nonwoven fabric. A backing sheet is formed in such a structure that an elastic nonwoven fabric is laminated with a film having water vapor permeability and water proofing property, whereby sufficient flexibility and excellent water vapor permeability are provided and help to keep skin respiration and not only to prevent skin irritation caused by stickiness with perspiration or the like but also to completely prevent permeation of water, a detergent aqueous solution or the like into a pad portion or an affected part and further to prevent infection of a wound with bacteria. The preventions can be more completed by sealing the edge portion of the adhesive bandage via heat-sealing or the like. Further, the use of the laminating film can realize improvement in break strengths and abrasion resistance of the adhesive bandage, and improve handling characteristics in adhering the adhesive bandage to the affected part.
