Abstract
The passage of a container along a conveyor is facilitated by applying to the container or conveyor aqueous compositions containing hardness ions. The compatibility of the aqueous compositions with PET bottles is improved when the ratio of hardness as CaCO3 to alkalinity as CaCO3 is greater than about 1 to 1.
