Abstract
The pressure sensitive adhesive bandage disclosed includes a novel low density polyethylene closed cell foam backing sheet with a glossy, smoothly pebbled, low friction, non-adherent face surface and a coating-adherent rear surface having a pressure sensitive adhesive to which is adhered an absorbent pad. In comparison with bandages having a vinyl backing sheet, the novel plasticizer-free polyethylene foam backing sheet provides improved shelf life, while its low density and low hand provides superior smoothness, flexibility, conformability and softness.
