- 1. A thermal insulation article for placement in a shipping container to hold an item, comprising:
a thermally insulating pad shaped to be positioned in a cavity of a rectangular prism shipping container to be adjacent to and cover one or more of a floor, four side walls and cover of the container while leaving an interior space to receive the item, wherein the pad includes:
a panel formed primarily of starch that holds together as a single unit, wherein the panel comprises one or more rectangular plates dimensioned to substantially span whichever of the floor, plurality of side walls or cover of the container that the one or more rectangular plates are adjacent, and
a compostable or recyclable film that sandwiches the panel and provides both an interior surface of the pad to face the interior space and an exterior surface of the pad to face the respective floor, plurality of side walls or cover.
- 14. A thermal insulation article for placement in a shipping container to hold an item, comprising:
a thermally insulating pad shaped to be positioned in a cavity of a rectangular prism shipping container to be adjacent to and cover two or more of a floor, four side walls and cover of the container while leaving an interior space to receive the item, wherein the pad includes:
a panel formed primarily of starch that holds together as a single unit, wherein the panel comprises a plurality of rectangular plates with each plate dimensioned to substantially span whichever of the floor, plurality of side walls or cover of the container that the rectangular plate is adjacent, and
a compostable or recyclable film forming a pocket enclosing the panel and providing both an interior surface of the pad to face the interior space and an exterior surface of the pad to face the respective floor, plurality of side walls or cover,
wherein the pad is foldable at a boundary between the plurality of rectangular plates.
- 24. A thermal insulation article for placement in a shipping container to hold an item, comprising:
a thermally insulating pad shaped to be positioned in a cavity of a rectangular prism shipping container to be adjacent to and cover one or more of a floor, four side walls and cover of the container while leaving an interior space to receive the item, wherein the pad includes:
