Abstract
A foldable blank is disclosed. The foldable blank includes a base, a first sidewall, a first flange, and a restraining feature. The first sidewall is connected to the base. The first flange is connected to the first sidewall. The restraining feature is located in at least one of the base and the first sidewall. Each of the base, the first sidewall and the first flange are constructed from a polymeric sheet. The restraining feature is a permanent imprint in the foldable blank. The foldable blank is generally planar with the exception of the restraining feature. The foldable blank may be erected to a folded tray. The folded tray may be connected with a lid to form a package. The package may be suitable for non-hermetic applications.

- a base at least partially bounded by a first bottom edge, a second bottom edge, a third bottom edge and a fourth bottom edge;
- a first sidewall connected to the base at the first bottom edge, the first sidewall at least partially bounded by the first bottom edge and an opposing first top edge;
- a second sidewall connected to the base at the second bottom edge, the second sidewall at least partially bounded by the second bottom edge and an opposing second top edge;
- a third sidewall connected to the base at the third bottom edge, the third sidewall at least partially bounded by the third bottom edge and an opposing third top edge;
- a fourth sidewall connected to the base at the fourth bottom edge, the fourth sidewall at least partially bounded by the fourth bottom edge and an opposing fourth top edge;
- a first flange connected to the first sidewall at the first top edge;
- a second flange connected to the second sidewall at the second top edge;
- a third flange connected to the third sidewall at the third top edge;
- and
- a fourth flange connected to the fourth sidewall at the fourth top edge;
- wherein each of the base, the first sidewall, the second sidewall, the third sidewall, the fourth sidewall, the first flange, the second flange, the third flange and the fourth flange are constructed from a polymeric sheet, and
- wherein at least one of the base, the first sidewall, the second sidewall, the third sidewall, and the fourth sidewall comprises a restraining feature that is a permanent imprint in the foldable blank.
