Heavy-Duty Boxes

When additional packing or shipping strength is required, use heavy-duty boxes to ensure the safety of the contents. Our Single Wall and Super Shipper boxes are made from 275#/ECT-44 corrugated cardboard and our Double Wall boxes are made from 275#D.W./ECT-48 corrugated cardboad. These heavy duty boxes start at 6"x6"x6" and progress to 48"x40"x36", with dozens of sizes in between. Our F.O.L (full overlap) construction boxes feature flaps that fully overlap; giving extra strength and protecting the edges. They are available in sizes ranging from 8½"x7"x73" to 40"x6"x40". All heavy duty boxes are available in bundle and bale quantities.
