ECT 48 - Heavy Duty Double Wall Boxes

Protect your heaviest and most fragile items with heavy-duty double wall boxes from Wrap-N-Pack.  These ECT 48 corrugated cardboard boxes provide extra stacking strength and twice the protection of a standard box. [MORE]

Double wall boxes help to protect products that are valuable, fragile and/or heavy. Since double wall boxes offer double the protection, you can be at ease knowing your product is shipping safely.

The new standard for determining corrugated box strength is the Edge Crush Test (ECT). This test measures the stacking strength of these corrugated boxes. A small segment of board on edge is compressed between two rigid platens until a peak load is established. This measurement is in pounds per lineal inch of load bearing edge, but is translated into an ECT value. Our double wall boxes have a ECT 48 value, so you can be assured that they are heavy-duty and able to handle a great deal of shipping weight.
