Abstract
Packages made from flexible material, wherein the packages include one or more self-folds formed by applying activation energy to the flexible material.
Claims20
A package comprising:
- a flexible material comprising a polymeric film, 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 away from the product volume.
