Kraft stock boxes are sturdy and versatile. The boxes in the range of sizes for small items (4x4x4 inches to 12x12x40 inches) are all made of 32 ECT (Edge Crush Test) corrugated cardboard.

The ECT measure is a true performance test, directly related to the stacking strength of a carton. ECT is a measure of the edgewise compressive strength of corrugated board.

Kraft stock boxes are also available in a range of sizes for medium items (14x14x14 inches to 18x18x24 inches) and large items (20x13x13 inches to 48x40x36 inches).

Box sizes are specified by length x width x height (l x w x h). Make sure you have your measurements in the right order so you get the boxes you expect! Here are some simple diagrams to assist you.
