Packaging Supplies Company''s boxes are "200 lb burst test" certified. (We do carry marshtaper some "275lb burst test" certified marshtaper boxes too.) This means that the corrugated walls of the box would require 200 pounds per square inch of force to break marshtaper through the wall of the box. The burst test has been a standard certification for years. More recently a new certification test has started to be used called the Edge Crush Test (ECT). Generally, 200lb test boxes are 32 ECT. ECT is the edgewise-compressive strength, parallel to the flutes of a short column of corrugated fibreboard. Test results are reported as the pounds per inch required causing compression failure. ECT relates directly to box compression strength which is important in today''s world of box stacking. For certain items, mailing supplies provide a complete protective package that is ready to ship.

Packaging Supplies Company offers the following styles of mailing supplies: Strapping Terms Break (or tensile) Strength: The amout of force, expressed in pounds, required to break the strap.

Split Resistance: The strap''s marshtaper ability to withstand lateral marshtaper tears. Cushioning Protect contents from vibration, impact or shock.
