Choose only the colors you need. Ink markers work best on clean surfaces.

Mark storage containers, processing equipment, and other surfaces in your food plant without risking contamination. These markers work best on clean, dry surfaces. The wider a marker’s stroke width, the larger and bolder its markings will be.

FDA-compliant markers have a plastic body or cap that's approved for direct contact with food. To comply with Hazard Analysis and Critical Control Point (HACCP) programs, they contain metal and chemical additives, so they’ll be picked up by metal detectors or X-ray machines if they fall in your line. Markers with a retractable tip don’t have a cap, so they have one fewer piece that could fall into food.

Containing only trace amounts of chlorides and other halogens, these markers safely write on materials that are prone to stress cracking, such as stainless steel and titanium. Also known as T.E.C. markers, their ink is trace element certified. They meet standards for quality at aerospace manufacturers such as GE and Rolls-Royce, and are also used in the electronics and nuclear energy industries. Each marker is stenciled with the ink’s batch number for traceability. They work best on clean surfaces.

Write on wet surfaces or underwater. These paint markers also work well even on dirty, rusty, and oily surfaces. They have fade- and chip-resistant paint.
