Abstract
An extruded hollow plastic board is described which has a pair of flat and parallel sheets spaced apart and interconnected by longitudinally extending ribs. The ribs and sheets are connected with rounded joint areas, which significantly improve the mechanical properties and solve undercut and die line problems existing with prior art hollow plastic boards. This invention also provides a method for the manufacture of the hollow board of thermoplastic resin thereof.
