Stratasorb Composite Island Dressing has four distinct layers designed to cover all stages of wound care. Layer 1, a non-adherent contact layer, protects the wound site and will not stick to granulating tissue. Layer 2, a soft pad, absorbs drainage. Layer 3, a non-woven backing with an adhesive border, securely holds the contact pad in place. Layer 4, a semi-occlusive, polyurethane film, helps deter external contaminants and maintain an optimal wound environment. Rectangular shape is designed for post-op applications. 4" x 10" 2" x 8" pad.
