Abstract: The inventive paper corrugated sheet is used to construct an improved modular corrugated crate that is reusable, recyclable, and biodegradable. The paper corrugated sheet is constructed from a laminated paper combination of aligned fluted paper and linerboard adhered together by adhesive. The sheet is constructed with a generally decreasing weight in laminated paper components from the outside of the paper corrugated sheet to the interior side, thereby improving strength and increasing the number of times that the crate can be reused.

Abstract: The inventive crate has a bottom base, two opposing side panels, two opposing interlocking end panels, and a top cap. The bottom base having a length and width larger than the X-width and Y-length dimensions of the cargo to be shipped, the opposing side panels are coextensive to the Y-length of the cargo as fitting within the bottom base lip and a height matching the cargo's Z-height. The interlocking end panels have a side interlock with a width slightly less than the thickness of the side panel, and a corner tab. When assembled, each side panel at each end inserts against the side interlocks at each corner compressively securing with the folding over of each corner tab crushingly sandwiching the side panel between the slightly crushed corner tab and center section as held fast by the bottom lip. The top cap covers the upper portion of the assembled panels.
