ABSTRACT:
Disclosed is a multi-layer sheet in a which a foamed thermpolastic core layer is extrusion coated with a multi-resin reclaim-containing layer, and an EVOH or acrylonitrile barrier layer is laminated to the multi-resin layer. The multi-resin layer is formulated to contain at least about 5 weight percent, and preferably about 8 to about 16 weight percent, based on the weight of the layer, of an adhesive resin to reduce the tendency of the barrier layer to delaminate from the multi-resin layer over time. The preferred adhesive is EMA.
