Abstract: An improved refrigerator cabinet construction is described which comprises, in laminated sequence, a metal outer layer, a foam layer, a composite release film and, strongly bonded thereto, an ABS layer. The laminate has a strong bond between all but two of the various contiguous layers and a weak bond between the remaining pair of contiguous layers, such that when the laminate is cycled between room temperature and -22.degree. C., only the weak bond is ruptured, the location of the weak bond being such that, in the event it were to be ruptured, the ABS layer and the portion of the laminate remaining adhered thereto would be reprocessable to produce an ABS with a Gardner impact strength that is at least 85% of that of the original ABS sheet incorporated in the laminate.

Abstract: The present invention relates to a composite sheet member having a plurality of coextruded laminar layers comprising a base layer having at least one exterior layer, said base layer being formed from a first polyblend of low grafted rubber content and said exterior layers being formed from a second polyblend having a higher grafted rubber content, said composite sheet having increased impact strength when impacted with a force through the base layer to the exterior layer.
