Abstract

Abstract The loose fill packing elements in one embodiment are constructed of a generally block C-shape and are of substantially uniform thickness throughout. Each of the elements has a central section to define an included angle of greater than 90°. The elements are made of any suitable expandable thermoplastic material which has resilient characteristics. The shape of the elements allows the elements to be readily flowable when being dumped into a shipping carton while also effecting an efficient nesting relationship when in place about an item being shipped in the carton. In another embodiment, the packing elements have the end sections splayed outwardly from the central sections.
