Abstract
A metal and X-Ray detectable polyurethane film having metallic particles blended into the polyurethane when in a liquid form and then having the film extruded so as to fully embed the metallic particles, such as iron oxide, across all areas of the film, which can be used in protective clothing, such as reusable aprons and sleeve covers, for example, in food processing applications. In this manner, the film permits easy detection, and thus removal of, damaged film portions that become detached from the protective garment and inadvertently introduced into the food being processed, before the final processing and packaging thereof.
