ABSTRACT:
A resilient prestressed honeycomb structure is disclosed in which at least one of its defined planar surfaces is cushioned along its lateral length by substantially continuously deforming it under compression to a preselected depth. Also disclosed is a one-step method for simultaneously cutting and forming a resilient prestressed paper honeycomb structure and apparatus therefor. One preferred embodiment of the resilient prestressed paper honeycomb structure is sufficiently strong and lightweight to use as an inner packaging for providing cushioning protection of articles having a fragility factor rating of less than about 85 G's against multiple impacts.
