摘要

An insulated cabinet wall structure for arefrigeration apparatus includes an outer wall defining aninner 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 adhesivefilm layer for adhering to the liner sheet outer surface, afilm of high elongation material, an additional adhesive filmlayer, and an outer barrier film layer. A foamed-in-placeinsulation is firmly bonded to the outer wall inner surfaceand the laminated film barrier film layer, the barrier filmlayer both preventing stress cracking of the liner anddiffusion of insulation foam blowing agents from theinsulation to the liner sheet.
