  • Method of making a liner construction
    Patent number: 3960631

The liner includes a plastic wall provided with a release layer on one surface formed of a material having a limited adhesion with an insulating foam which is subsequently foamed-in-place thereagainst thereby permitting separation of the liner from the foam as a result of differential thermal contraction of the liner and foam thereby avoiding stress cracking of the liner. The liner wall is defined by a sheet of the plastic material which is provided with the release layer and subsequently formed into the desired refrigerator liner configuration.
