Any questions? Contact our support team

Are these 20x20x6 corrugated boxes strong enough for shipping wide, flat items?

Yes. With a 32 ECT-C edge-crush test rating, these single-wall boxes can safely hold up to 40–45 lbs when packed properly. The large square base and shallow height make them ideal for shipping trays, framed artwork, printed materials, folded apparel, or flat product kits that need surface area more than depth.

Is the 32 ECT-C rating acceptable for FedEx, UPS, and USPS ground services?

Absolutely. A 32 ECT single-wall box meets or exceeds the minimum strength requirements set by major carriers for ground shipping. Just be sure to use void fill if needed, tape all flaps securely, and stay within the weight limit for best results.

What does the 32 ECT-C classification mean?

ECT (Edge Crush Test) measures the box’s ability to withstand pressure along its edge. A 32 ECT board resists 32 pounds per linear inch before failure. The “C” flute profile offers a solid balance of stacking strength and cushioning performance in single-wall packaging.

How many boxes are included, and how are they shipped?

Each case contains 25 boxes, shipped flat in a bundled package to minimize freight costs and save storage space. Assembly is quick—just square up the box, fold the flaps, and tape the bottom securely.

Are these boxes made from recycled content, and are they recyclable?

Yes. These boxes are made from Kraft linerboard that typically includes 30–40% post-consumer recycled fiber. After use, remove any tape or labels and recycle them through your local corrugated collection stream.

Can these 20x20x6 boxes be stacked on a pallet?

Yes. Their shallow height allows for more layers per pallet. When loaded within the 40–45 lb limit and stacked uniformly, these boxes can be safely palletized. For added stability, use slip-sheets or chipboard between layers and secure the stack with stretch wrap.

Are these boxes safe for direct food contact?

No. Although the linerboard is non-toxic, it is not certified for direct food contact. If using for food-related applications, we recommend inserting a food-grade poly bag or liner.

Do I need special tools or adhesives to assemble the boxes?

Not at all. These boxes are pre-scored for fast folding and only require standard 2"–3" wide carton-sealing tape for assembly—no glue, staples, or special equipment necessary.
