Abstract
Packaging devices such as bags, pouches, envelops, containers, and the like, can include an integrated heating system. The packaging devices described herein have multiple potential uses such as for the containment and heating of single-serving meals, drinks, massage oils, masks, body wax, anti-wrinkle eye creams, and the like, to be heated on the go. The packaging devices described herein can also be used for instant heating of food and/or beverages for backcountry use. In some embodiments, the packaging devices use fibrous natural materials (e.g., leaf skeletons and soft biomaterials like chitosan) along with silver nanowires to create completely biodegradable, and reusable self-heating packaging.
