A new antiblock masterbatch for polyolefin films is said to maintain low haze and high clarity better than conventional antiblocking agents. Ingenia 1091 from Ingenia Polymers Inc., Houston, is also said to produce a permanent antiblocking effect. Its effect on film clarity was compared with widely used diatomaceous earth in LDPE blown film. Both antiblocks were used at 1500 to 15,000 ppm. Film containing no antiblock had a haze value of 8.5%. Films containing diatomaceous earth had haze from 9% to 19%, while Ingenia 1091 produced haze from 8.5% to 13.5%.
