ABSTRACT OF THE DISCLOSURE An in-line method of forming a laminate of a heat sensitive foam sheet material, and a hot extruded polymeric product comprising hot extruding a polymeric material into a shaped product and while still hot contacting the shaped product with a face of the heat sensitive foam sheet material and thereafter cooling the resulting product. Such face is previously coated with a layer of a heat sealing substance which is activated at a temperature below the softening point of the heat sensitive foam sheet. The heat seal contact takes place under minimal pressure when the surface temperature of the shaped product is still high enough to activate the heat sealing sub- stance but not high enough to damage the hoat sensitive sheet. The laminates so made are part of the invention.
