A range of blue detectable plasters are supplied with an aluminium sheet under the wound pad that can be detected by a metal detector making them ideal for employees working in the food processing and handling areas. They protect against cross contamination between blood and the products handled, whilst providing a visually detectable product due to its blue colour should the plaster become loose. All our blue detectable plasters are tested according to ISO 10993 and are hypoallergenic, non-cytotoxic and latex free.
