Disclosed are wound closure strips which have an uniaxially oriented, silica filled, polyolefin substrate, a medical grade pressure sensitive adhesive, and a release sheet covering the pressure sensitive adhesive. Such strips are breathable, tearable to size, and may be removed from the skin with an alcohol wipe. Multiple wound closure strips are mounted on the upper surface of a backing sheet and pressure sensitive adhesive patch coated on the lower surface of the backing sheet, thereby making it possible to adhere the backing sheet to a surface near the intended point of use and, then, easily remove and handle the wound closure strips with a gloved hand. The wound closure strips may be color-coded and used not only for incisions and wounds but also for attaching catheters, and other medically related uses. Sterile packages of multiple wound closure strips make them useable in a sterile operation room arena.
