First Aider's Choice detectable plastic strips are useful for food preparation, pharmaceutical and manufacturing processing sites. The internal foil makes quick detection possible in plants that require metal detectable products. The non-stick pad contains metal foil underneath the pad and if lost it will trigger a pre-tested metal detector. The bright blue colour are highly visible making them easy to spot if they fall off. The strips are extra wide and made from a flexible fabric that is water resistant. Perfect for industries such as restaurants, hospitality, catering, cafeterias, pharmaceutical and manufacturing.
