Abstract

A dielectrically-heatable inventive method employing a polyolefin-based formulation including at least 5 weight percent of a zeolite, ion exchanged with a Group I or II metal, wherein the zeolite includes 21 or less wt % of water, based on zeolite weight, measured as LOI at 575° C. for 1 hour; and a base polymer selected from certain homogeneously branched linear or substantially linear ethylene/α-olefin or homogeneously branched propylene/?-olefin copolymers copolymers, provided that the base polymer has a melt temperature less than 100° C. This formulation may be used to prepare a high frequency (HF) welded article having improved failure and welding strength properties, particularly a weld strength in excess of 7 lb/in (1.23 N/mm).
