摘要： A multi-layer, high barrier packaging lid material (10) 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 (12) with internal wet strength agent and an anti-wicking agent. On the interior of the base are a polymer oxygen barrier layer (18), a tie layer(s) (20, 22), and a seal-peel layer(s) (24,26) on the tie layer(s). The exterior of the base may include optional coating layers (14, 16). The seal-peel layer comprises a blend of first and second polymers. When the Hd material is heat sealed to a first container, the first polymer bonds with the first container while the second polymer functions as a contaminant to provide easy peeling. When the lid material is heat sealed to a second container, the second polymer bonds while the first polymer functions as the contaminant.

摘要： Bio-degradable, high-barrier packaging materials and methods for production are provided. The present high-barrier packaging materials include a substrate having a print side and a back side, a coating having nano pigments on the print side and a metalized film applied to the back side with a binding layer. Preferably, at least one of the metalized film and the binding layer includes polylactic acid. Moreover, the back side preferably also includes a polylactic acid heat seal layer.
