1. A food container obtained by:
creating a fiber-based slurry, the fiber-based slurry comprising fiber-based pulp containing a moisture barrier component in the range of 1%-10% by weight;
wherein seme at least a portion of the moisture barrier component is absorbed in the fibers; forming a mesh in the shape of a mold corresponding to the shape of the food container; immersing the mesh in the fiber-based slurry;
drawing a vacuum across the mesh to cause fiber particles from the fiber-based slurry to accumulate at the mesh surface; and
removing the mesh and the accumulated fiber particles from the fiber-based slurry;
drying the accumulated fiber particles to remove moisture, where the dried accumulated fiber particles form the food container;
spraying at least one of a topical oil barrier coating and a topical vapor barrier coating to a surface of the food container, and wherein,
the fiber-based slurry further comprises a dye absorption agent comprising one of salt and soda ash; wherein at least a portion of the dye absorption agent is absorbed in the fibers.
