Abstract

Disclosed are devices and liners for containing item(s) or fluid(s) at a temperature below ambient temperature comprising: (a) a container or compartment having an interior space and (b) thermal insulation comprising a polymeric material having closed cells therein wherein said cells are formed from and/or contain a blowing agent, said container comprising a liner comprising (i) a first layer comprising ABS and having a surface facing toward said interior space; and (ii) at least a second layer having a surface facing away from said interior space and toward said thermal insulating foam, wherein said second layer of said liner is at least one of (1) a layer formed from an amorphous or semi-crystalline polyamide resin having sufficient composition and thickness to substantially inhibit the migration of said blowing agent toward said interior space; (2) a layer formed from a polymeric material capable of absorbing a substantial portion of said blowing agent molecules emitted from said insulation; and (3) a layer containing a material capable of reacting with a substantial portion of said blowing agent emitted from said insulation.
