Abstract

A honeycomb web precursor includes a body of polymer material having a series of branched slits. The body is capable of expanding into a web of honeycomb construction. Various panels and partitions are also disclosed. A method is also provided for producing a honeycomb web of polymer material. That method includes the making of a series of branched slits in a body of polymer material so as to define multiple expansion ribs and the expanding of the body and erecting of the expansion ribs by folding so as to form the honeycomb web.
