ToughMark labels have a repositionable adhesive and a synthetic face, making them extremely durable. They are designed to be transferred and reused multiple times. Labels do not lose adhesion in "steamy" environments so they work great on steam tables. They will not tear or leave residue when they are transferred among different containers. ToughMark labels help ensure that food is appropriately labeled and handled according to HACCP guidelines. Labels work in temperatures ranging from -20º F to 250º F.
