Abstract: A method may be used to specify at least one operating parameter for a blow-molding process. The method comprises: providing a pre-formed geometry; providing a target-object geometry; providing at least one target-object property value range; specifying a value range for the at least one operating parameter; providing a representation of process blow fluid behavior; providing a pre-form resin material model; calculating a finished-object property a plurality of times, each finished-object property calculated according to the pre-formed geometry, target-object geometry, process blow-fluid behavior, pre-form-resin material model, and a value of the at least one operating parameter within the operating parameter value range; identifying operating parameter values associated with the calculation of finished-object properties within the target-object property value range; specifying at least one of the identified operating parameter values as the operating parameter of the blow-molding process.

Abstract: A packaged potable liquid, such as bottled water, wherein the liquid has little or no plastic off-taste. The packaged liquid includes a closure wherein the closure shell or the liner within the closure comprises a plastic matrix and an organic slip agent dispersed in the plastic matrix, the slip agent being substantially fully ethylenically saturated and the closure or the liner being substantially free of an ethylenically unsaturated compound. The packaged liquid also includes a container which is desirably substantially free of an ethylenically unsaturated compound.
