<p>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 barrier film material is linear low density polyethylene. 39,313-F</p> |
