STRUCTURAL MEMBER FOR PACKAGING TYPICALLY TUBULAR WITH CENTRAL CORE OF STACKED CORRUGATED PAPERBOARD AND EXTERIOR FIBREBOARD SHEET

摘要

A structural member formed from a billet, each member comprising a plurality of corrugated paperboard sheets bonded together with an adhesive and disposed between a core fibre layer, each core fibre layer comprising at least one ply of a fibreboard sheet, a pair of caps of a solid fibreboard sheet bonded to respective side faces of the paperboard sheet and to the respective edges of the core fibre layers. A method of manufacture is disclosed in which the billet is built up of corrugated paperboard sheets. The billet is then ripped into planks for use as a plank, board, or cleat, particularly as components for corrugated paperboard containers. A pallet made of planks and a pallet made of planar sheets cut from the billet are disclosed.
