Self-laminating HMIS tags have a writable surface that accepts writing from a pen, pencil, or marker. After filling the respective fields, the tags can be protected with a 2 mil thick, clear-polyester flap that seals the writing. To use the flap, remove the adhesive liner and press down on the tag’s surface. This protects the writing from rain, weather, and vandals. Tags are reinforced with a metal eyelet for tear resistance when attached to a container using wires and plastic ties.
