A cellular cushioning article strand in fan-folded configuration has embossed film bonded to backing film with entrapped air between the films. The embossed film has 15 to 40 percent land area and 85 to 60 percent embossed area. The embossments of a first ply are nested into the embossments of a second ply, with the first and second plies having a height under 0.05 psi load corresponding with a nesting level of at least 1 percent measured against two roll-stacked plies of the same cellular cushioning article under the same load. A strand of cellular cushioning fan-folded into at least 20 plies exhibits a post-0.05 psi temporary loading nesting level of at 1 percent relative to the post-0.05 psi temporary loading height of 20 plies of the same cellular cushioning article in roll-stacked arrangement.
