Are these 12x12x6 corrugated boxes strong enough for shipping flat or wide items like books, apparel, or accessories?

Yes. With a 32 ECT-C edge-crush test rating, these single-wall boxes offer reliable protection for lightweight, low-profile items. They’re ideal for shipping items like clothing, framed prints, manuals, or stacked parts—anything that fits within the shallow 6" depth. When properly packed, they support up to 40–45 lbs.

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

Absolutely. A 32 ECT single-wall box meets the standard strength requirements for ground shipping with major carriers. Just be sure to secure all flaps with tape, avoid exceeding the weight limit, and fill voids as needed to prevent product shifting.

What does the 32 ECT-C classification mean?

ECT (Edge Crush Test) measures a corrugated board’s ability to withstand crushing force on the edge. A 32 ECT board can handle 32 lbs of pressure per linear inch. The “C” flute designation refers to a medium-thickness flute profile, which balances cushioning and stacking strength in single-wall packaging.

How many boxes come in a case, and how are they shipped?

Each case includes 25 flat-packed boxes. The boxes ship bundled to reduce freight and storage costs. Assembly is simple—just square the box, fold in the bottom flaps, and seal with carton-sealing tape.

Are these boxes made from recycled materials, and can they be recycled after use?

Yes. These boxes are made from Kraft linerboard that generally includes 30–40% post-consumer recycled content. After use, remove tape and labels before recycling through your local corrugated stream.

Can these shallow 6" boxes be stacked on a pallet?

Yes, though due to the shorter height, more layers will be needed. When packed within the 40–45 lb weight limit and stacked with even loads, these boxes can be palletized efficiently. For added protection, use slip-sheets or chipboard between tiers to prevent shifting during transit.

Are these boxes suitable for direct food contact?

No. While the material is non-toxic, it is not certified for direct food contact. If using for baked goods or other food items, a food-safe liner or poly bag should be used.

Do the boxes require special tools, glue, or staples to assemble?

Not at all. These boxes are pre-scored for fast folding and only require standard 2"–3" carton-sealing tape to close the top and bottom securely.
