Abstract

Abstract The loose fill packaging material of the illustrated embodiment comprises a plurality of elements of, for example, expanded polystyrene. Each packaging element of the embodiment is of a generally block-like form which includes a body portion of a spring-like construction and two leg portions. The spring-like construction is formed by slitting a surface of the body portion at spaced-apart locations prior to the complete expansion of the packaging element.
