Another salient object of my invention is to provide a

The improved packaging strip S includes a continuous

material, such as chip board, corrugated board or the like,
and the outer continuous ply 11. The outer ply 11 is
folded transversely at spaced points to provide outwardly
projecting peaks and straight connecting portions 13 be
tween the peaks. The straight connecting portions 13
abut the inner ply 10' and are secured to the inner ply in
any suitable manner, such as by the use of an adhesive
or by metal staples or stitches.
In the form shown in

these peaks can take any desired form. In accordance
with my invention, the peaks ‘12 are provided with trans

longitudinal alignment, so that the strips can be folded
along the slits into a substantially U-shape in cross-section
with outwardly extending cushioning peaks and laterally
extending cushioning peaks.
A further important object of my invention is to pro

the peaks and down to the inner ply '10‘. The slits weaken
