Abstract
An insulated cabinet wall structure for a refrigeration apparatus includes an outer wall defining an inner surface and a plastic liner defining an outer surface. A laminated film is adhered to the liner sheet outer surface, the film comprising in laminated sequence an inner adhesive film layer for adhering to the liner sheet outer surface, a film of high elongation material, an additional adhesive film layer, and an outer barrier film layer. A foamed-in-place insulation is firmly bonded to the outer wall inner surface and the laminated film barrier film layer, the barrier film layer both preventing stress cracking of the liner and diffusion of insulation foam blowing agents from the insulation to the liner sheet.
