18 x 16 x 16" Double Wall Boxes

The 18 x 16 x 16 inch double wall corrugated box is built for shipments that exceed the limits of standard single wall packaging. ECT-48 double wall construction sandwiches two fluted medium layers between three liner sheets, delivering measurably greater stacking strength and puncture resistance than ECT-32 alternatives.

These boxes are a reliable choice for heavier consumer goods, dense industrial components, automotive parts, and fragile items requiring extra wall integrity during transit and storage. The cubic interior accommodates products that need balanced depth-to-footprint proportions, making them practical for both outbound fulfillment and warehouse storage applications.

Each box weighs approximately 2.56 lbs, reflecting the added board mass of double wall construction. Boxes ship and store flat to reduce floor space demands until they reach the pack line. Sold in bundles of 10, with parcel-friendly sizing for standard replenishment orders.
