ABSTRACT:
Polyesters and polyester containers having a reduced coefficient of friction and improved clarity are produced using an antiblock agent comprising a dried talc having from about 20 to about 300 ppm water or a fatty acid tethered talc. The use of these talcs result in polyesters and polyester containers having a coefficient of less than about 1.0 and a clarity with haze values of less than about 4%.
