A method of making a foam filled polymer article includes the steps of compressing an expandable foam material (12) and containing the compressed expandable material (12) in a degradable container, such as a polyethylene bag (16). An outer polymer shell (10) is formed while degrading the container (16) therewithin, such as by rotation molding. The shell (10) is filled with the uncontained expandable foam material (12).
