You can iron the crushed paper if you want to save it.
Corrugated Board - Ring Crush Test : Ring Crush is a traditional test of linerboard and corrugating medium strength. Ring crush measures compression resistance, and this compression strength is considered to relate to the eventual compression strength of combined board made from the component. Linerboard called high strength or high performance linerboard is board that is able to achieve a specified minimum ring crush at basis weights that are lower than traditional basis weights. Corrugated Board - Concora Crush Test : The Concora Crush Tester performs a series of tests to determine the rigidity and crush resistance of corrugated material. It is used in conjunction with the Concora Liner Tester. The first test measures the flat crushing resistance of a laboratory-fluted corrugated material. The second test determines the edgewise strength, parallel to the flutes, of a short column of single-, double-, or triple-wall corrugated board. The third test evaluates the ability of corrugated material to contribute to the compression strength of a corrugated box by measuring the edgewise compression strength of a laboratory-fluted strip of corrugated material in a direction parallel to the fluted tips. Corrugated Board - Flat Crush Strength : The flat crush test is a measure of the resistance of the flutes in corrugated board to a crushing force applied to the surface of the board under prescribed conditions. Flat crush is a measure of the flute rigidity of corrugated board. A high flat crush value indicates a combination of good flute formation and at least adequate strength medium. Low flat crush may indicate a number of conditions including low strength medium, leaning flutes and crushed flutes.From: http://www.thaicorrugated.com/knowledge.php?cid=30
The Concora Medium Test - CMT measures the crush resistance of a laboratory-fluted strip of corrugating medium. This test is one of a number of tests for crush resistance made on the components of corrugated board to gauge its contribution to the strength performance of the corrugated box produced from board. The load is applied in the lengthwise direction of the paper web; the maximum load applied to the test piece is recorded as the measure of the medium compression strength.

There is one i know of and that's paper board but I'm not sure about any others ^_^ Grey board

Corrugated boxCorrugated box is box made out of corrugated box made of paper based corrugated fiberboard. Corrugated fiberboard is a paper-based material consisting of a fluted corrugated sheet and one or two flat linerboards. It is widely used in the manufacture of corrugated boxes and shipping containers. Corrugated liner marked with parallel folds, ridges or furrows bent into regular curved folds or grooves. Process of making such regular curved folds is called corrugation.

Converted paper refers to paper that has been processed into a different form or product than its original sheet or roll. This can include products such as envelopes, cardboard boxes, labels, or packaging materials that are made from paper pulp.
Most corrugated boxes are made using a combination of paper, adhesive (glue), heat and pressure. Boxes made from recycles paper usually indicate this on the bottom of the box.
A Corrugator is a machine used to form paper into corrugated material, the basis consist of a liner (top and bottom) the medium (corrugated part in the middle) and starch.

Reels of paper are fed into a machine which treats it with steam and heat conditions it into the corrugated shape. A liner is then applied and glued to the corrugated layer. A separate liner is then glued onto the other side.
