This invention relates to the use of a barrier film, being a thermoplastic linear polyolefin resin, to protect a styrenic resin sheet which constitutes the inner liner wall of an insulative cabinet wall of, for example, a refrigeration appliance unit from attack by the halogen-containing blowing agents present in the insulative polyurethane foam found within the cabinet wall. Preferred thermoplastic linear polyolefin resins are linear low density polyethylene.

Polyolefin barrier films for preventing solvent attack on plastic resins

This invention relates to the use of a barrier film consisting essentially of thermoplastic homo- or copolymer polyester resin to protect a styrenic resin sheet which constitutes the inner liner wall of an insulative cabinet wall of, for example, a refrigeration appliance unit from attack by the halogen-containing blowing agents present in the insulative polyurethane foam found within the cabinet wall.
