Abstract
This invention relates to a multilayer thermoformable structure comprising (A) at least one cap layer and (B) at least one core layer, and polymer compositions for making the same. The multilayer structures and polymer compositions of the invention are useful in preparing thermoformed articles and are particularly useful in preparing liners for refrigerators and freezers. The multilayer structures and the polymer composition have good thermoformability and chemical resistance. The multilayer structures and the polymer composition have good surface properties including a glossy finish. Further these materials are compatible with new blowing agents, such as the hydrochlorofluorocarbons and hydrofluorocarbon blowing agents, which are more environmentally friendly. The layers of the multilayer structure do not require a glue layer.
