A substance that is added to the surface of another material to minimize adhesion. Antiblocking agents, such as chalk, talc, and clay, are added to the surface of vinyl and polyolefin films to prevent sticking when multiple layers are placed together. Antiblocking agents are also added to wax coatings to minimize bloom by forming an impenetrable layer on the surface.
