Abstract
Disclosed herein are polymer-based films (and articles of manufacture made therefrom or comprising thereof). In several embodiments, the film comprises biodegradable polymers. In several embodiments, the film comprises post-consumer recycled material. In several embodiments, the film comprises an odor absorbing agent (e.g., carbon). In several embodiments, an article of manufacture comprising a film as disclosed herein or the film itself is biodegradable.
Claims27
A trash bag, comprising:
- a multilayer sidewall providing an inner surface of the trash bag, the multilayer sidewall having a thickness spanning from an outside surface of the trash bag to the inner surface of the trash bag, the multilayer sidewall comprising:
- at least a first layer, a second layer, and a third layer, the first layer comprising a biodegradable polymer, the second layer comprising a post-consumer recycled (PCR) plastic, and an odor control agent, and the third layer comprising a biodegradable polymer,
- wherein the first layer provides the outside surface of the trash bag and the second layer is located more proximally to the inner surface of the trash bag than the first layer, wherein the second layer provides a pathway for odors to reach the odor control agent, and wherein the second layer is biodegradable,
- wherein the second layer comprises the PCR plastic at a weight percent of equal to or at least about 50% and wherein the second layer comprises the odor control agent at a weight percent of equal to or at least about 1%.
1 more element
A multilayer film comprising:
- at least a first layer, a second layer, and a third layer, the first layer comprising a biodegradable polymer, the second layer comprising a post-consumer recycled (PCR) plastic and an odor control agent, and the third layer comprising a biodegradable polymer,
- wherein the second layer has a thickness that is greater than the thickness of the first layer, wherein the second layer provides a pathway for odors to reach the odor control agent, and wherein the second layer is biodegradable,
- wherein the second layer comprises the PCR plastic at a weight percent of equal to or at least about 50% and wherein the second layer comprises the odor control agent at a weight percent of equal to or at least about 1%.
