A multi-layer sheet includes an insulative cellular non-aromatic polymeric material, a film, and a polymeric-lamination layer. The insulative cellular non-aromatic polymeric material may be formed from a polymeric formulation comprising a base resin blend and a physical nucleating agent.

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.

A thermoformed packaging unit is produced from a thermoformable sheet that has a printed pigment deposit located generally in a central position between the first and second rigid components. The packaging unit has only a low level of pigment distortion even when thermoformed to a draw ratio greater than 4.

A coinjection molded multi-layer container includes an inner layer, an outer layer, and a barrier layer. The inner layer includes a first polymeric material and forms an inside surface of the container. The outer layer includes the first polymeric material and forms an outside surface of the container. The barrier layer is located between the inner layer and the outer layer and includes a second polymeric material less permeable to gas than the first polymeric material. The barrier layer is biased toward the inside surface or the outside surface such that the inner layer and the outer layer have different thicknesses.
