Two new antiblock products have been launched for use in plastic film and bag applications. Specialty Minerals Inc., a wholly owned subsidiary of Minerals Technologies and a leader in mineral additives, has launched Optibloc® 8 and Optibloc® 325 talc blends, new antiblocking products for high-clarity film and bag applications. Antiblocks are used to prevent the adhesion of two adjacent layers of film, a problem most associated with polyethylene and polypropylene films. These new products are designed for high-clarity polyethylene film applications such as food packaging and clear bags. OPTIBLOC® 8 and OPTIBLOC® 325 talc blends have excellent antiblocking efficiency and provide high-clarity with low-haze films. OPTIBLOC® 8 antiblock is the next generation of Minerals Technologies' patented OPTIBLOC® antiblock product line, which is utilized globally in polyethylene films.
