Bioclusive Plus Transparent Film Dressing is self-adhesive. This dressing is made from a transparent, semi-permeable polyurethane film that is coated with an acrylic adhesive. It provides a barrier to viruses 27mm in diameter or larger, such as HIV and Hepatitis B, and to bacteria. The semi-permeable film allows the transmission of oxygen and moisture vapor, helping to prevent periwound maceration. Transparent, for inspection of the wound for the duration of wear. Size: 5-3/8" x 7-7/8". 10/box.
