Abstract
Abstract A wrap for receiving and surrounding an impregnated dressing to prevent it from sticking to a foil pouch in which the wrap and dressing are received characterized by a sheet-like member folded to form first and second panels having flaps on an edge opposite said fold line to enable easy opening of the wrap to expose the dressing. Preferably, the wrap is formed of a material such as paper which enables opening of the wrap to release the dressing without damaging or distorting the dressing.
