摘要： A container thermoformed from a polymeric multilayer sheet includes a cavity for containing food. The sheet includes a polymeric interior layer positioned between (i) a polymeric outer layer of the sheet and (ii) a polymeric inner layer of the sheet that is in opposing face-to-face relation with, and at least partially defines, the cavity of the container. The interior layer includes post-consumer recycled polymeric material. The sheet includes a polymeric barrier layer positioned between the interior layer and inner layer. The barrier layer restricts inward passage of at least some of any gasses originating from the post-consumer recycled polymeric material.
