I need a commercially available ink to apply markings to rotationally molded polyethylene (LLDPE). Ink must be available in red, yellow, black white and green. Would strongly prefer not to have to pre-treat area for marking (flame treat etc.)
Try Sun Chemicals Corporation (in the US) they are owned by Dainippon Ink from Japan. This conglomerate is the largest ink maker in the world. Inks made for flexo printing on plastic packaging may be a good starting point.
