Abstract
A backing sheet for use in a wound dressing includes a semipermeable continuous film laminated to an adhesive-coated apertured layer. The apertured layer is a solid substrate coated with a medically acceptable adhesive. A method of making a backing sheet for use in a wound dressing includes the steps of: forming an adhesive-coated apertured layer by coating a medically acceptable adhesive onto an apertured solid substrate, followed by laminating the adhesive-coated apertured layer to a semipermeable continuous film.
