Abstract

See full text

A multi-layer, high barrier packaging lid material is adapted for releasably sealing to a plurality of containers including a first container comprised of one polymer and a second container comprised of another polymer. The packaging lid material comprises a paper base with an internal wet strength agent and an anti-wicking agent and having interior and exterior surfaces. A polymer oxygen barrier layer is bonded on the interior surface of the base. A tie layer is on the barrier layer, and a seal-peel layer is on the tie layer. The seal-peel layer is comprised of a blend of a first polymer and a second polymer. When the lid material is heat sealed to a first container the first polymer in the seal-peel layer bonds with the first container while the second polymer in said seal-peel layer functions as a contaminant to provide easy peeling. When the lid material is heat sealed to a second container the second polymer in the seal-peel layer bonds with the second container while the first polymer in the seal-peel layer functions as a contaminant to provide easy peeling.
