Abstract
A biodegradable jar has an enclosure wall with a cap that form ajar that holds a semi-solid material. In order to prevent the biodegradable wall from being weakened by the semi-solid material in the jar, both an exterior surface and an interior surface of the wall and the cap include a permeation barrier material that substantially prevents the semi-solid material from seeping through the walls of the jar. The enclosure wall could have an inner wall that is shorter than the outer wall which forms a ledge that a separate cover for the semi-solid material could rest upon.
