Abstract
Abstract A pallet is formed by folding and gluing two pieces of corrugated board. A first or base piece is formed of three parallel spaced channel sections connected by platform reinforcing portions. A second or platform piece is formed mainly of a platform resting upon the platform reinforcing portions of the first piece and has flaps depending perpendicularly downwardly into each end of each of the channel sections. Tabs hinge outwardly from the flaps and are secured to the sides of each of the channel members by gluing.
