Box reinforcing sheet with self-stick layer

Abstract

A reinforcing sheet structure for reinforcing a box has a structural base sheet of high shear strength and an extended length and width dimension equal to major parts of at least two of the box length, width, and height dimensions, and a double-sided adhesive layer having an extended length dimension corresponding to a major part of one of the base sheet's length and width dimensions. In one embodiment, the reinforcing sheet structure includes a plywood sheet and an intermediate corrugated sheet bonded to the plywood sheet. The adhesive layer is a double-sided foam tape. In another embodiment, the sheet structure has at least one fold line for folding the sheet structure into two parts for reinforcing over a fold line between adjacent sides of a box. The reinforcing sheet structure may be used in multiple combinations both inside and outside the box.
