Flexible packages with self-folding

A package comprising:

• a flexible material comprising a polymeric film, wherein the polymeric film is formed from one layer of polymer, wherein the polymer is a single type of polymer, and wherein the flexible material defines an enclosed product volume;
• a first panel formed from the flexible material, wherein at least a portion of the first panel is adjacent to a self-fold in the flexible material, and wherein the portion of the first panel adjacent to the self-fold is about flat;
• and
• a second panel formed from the flexible material, wherein at least a portion of the second panel is adjacent to the self-fold in the flexible material, and wherein the portion of the second panel adjacent to the self-fold is about flat;
• wherein the self-fold has an overall thickness that is about 5% to about 30% greater than a thickness of the flexible material outside of the self-fold;
• wherein the self-fold has a differential thermal-mechanical set than the flexible material outside of the self-fold;
• wherein the self-fold forms an angle of about 100 degrees to about 170 degrees between the first panel and the second panel;
• and
• wherein the angle faces toward the product volume.
