Abstract
A hinged flexible polyurethane foam protective packaging element is formed from a flexible polyurethane foam laminated to a polyethylene, polypropylene or urethane film. The flexible polyurethane foam has a density in the range of 0.7 lbs/ft to 2.8 lbs/ft and IFD in the range of 25 lbs to 270 lbs. The film has a thickness from 2 mil to 125 mil. The foam is cut through all or substantially all of its thickness without cutting through a portion of the film. The uncut portion of the film creates a repeatably bendable hinge.
