Abstract: A compostable material and methods of forming the same are described. The compostable material includes about 90% to about 99% by weight of a compostable polymeric material and a nucleating agent. The compostable material has a degree of crystallinity of about 5% to about 45%.

Abstract: A compostable food packaging container. The container may have from about 84% to about 94% by weight cPLA, from about 5% to about 15% by weight of an oxygen barrier material, and one or more additives. In some embodiments, the container may be a beverage pod. The oxygen barrier material may be polyglutamic acid in some embodiments. In other embodiments, the oxygen barrier material is ethylene vinyl alcohol. The oxygen barrier material may be a food contact grade material. The one or more additives may include an impact modifier and a nucleating agent in some embodiments. Moreover, the one or more additives may include a pigment. The food packaging container may be formed of a sheet material having one or more layers. The sheet material may be extruded, co-extruded or laminated. In some embodiments, the sheet material may be thermoformed or vacuum formed to form the container.
