These new products are designed for high-clarity polyethylene film applications such as food packaging and clear bags.

Jan 9 2012 --- Minerals Technologies Inc., a worldwide manufacturer of minerals products, has launched two new antiblock products 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.

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.
