Abstract: Films and packaging materials including biodegradable and edible components and pods created using these materials are described herein. The water-soluble film includes a biodegradable polymer, a polyhydric alcohol, polyhydric acid, or combinations thereof, an emulsifier, surfactant, or combination thereof, a chelating agent, and a bulking agent.

Abstract: Methods for making water-soluble films include forming a film base composition comprising a biodegradable polymer and a film base solvent, forming a casting base composition comprising a polyhydric alcohol, a polyhydric acid, or combinations thereof, a chelating agent, an emulsifier, a bulking agent, and a casting base solvent, and mixing the film base composition with the casting base composition to form a casting composition. Then, a film is cast from the casting composition to form a resulting water-soluble film. The water-soluble film includes 20 wt. % to 50 wt. % biodegradable polymer, 5 wt. % to 40 wt. % polyhydric alcohol, polyhydric acid, or combinations thereof, 4 wt. % to 10 wt. % emulsifier, surfactant, or combination thereof, 5 wt. % to 25 wt. % chelating agent, and 15 wt. % to 45 wt. % bulking agent, which are each based on the total weight of the water-soluble packaging film.
