ABSTRACT:
Cornerboard protector comprises laminated cardboard or paperboard with embedded reinforcement strip, which is bent at a right angle along its length, the reinforcement strip being embedded only in the unbent portion of the strip. A V-cut in the bent portion and extending into the unbent portion with its apex terminated just short of the reinforcement strip provides a mitered corner about which the laminate is folded to form a neat and strong corner protector.
