Abstract
Abstract An edge protection device for protectively packaging articles. The edge protection device is interposed between the edges of the article and the edges of the inner walls of a shipping container. The protection device includes a set of fluted members joined to each other in a longitudinal direction. The fluted members pass in a direction substantially perpendicular to the longitudinal direction. Each fluted member is composed of a pair of rib elements formed in continuous relation to each other providing an apex at an intersection of the rib elements. The edge protector may be formed of molded plastic and is contoured to provide a multiplicity of load bearing surfaces.
