Any questions? Contact our support team

Are these 16x16x12 corrugated boxes strong enough for shipping bulky or fragile merchandise?

Yes. With a 32 ECT-C edge-crush test rating, these single-wall boxes provide reliable strength for larger and heavier items up to 40–45 lbs. The spacious interior and square footprint make them ideal for shipping items like household goods, decor, product kits, blankets, or irregularly shaped parts that need room and protection.

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

Absolutely. The 32 ECT single-wall specification meets the edge-crush strength standards required by all major carriers for ground shipments. For best results, pack contents with cushioning, secure the flaps with strong tape, and do not exceed the recommended weight capacity.

What does the 32 ECT-C classification mean?

ECT (Edge Crush Test) measures how much compression a corrugated board can withstand at its edges. A 32 ECT rating means the box resists 32 pounds of pressure per linear inch. The “C” flute is a common profile offering a solid balance between strength, cushioning, and crush resistance in single-wall construction.

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

Each case includes 25 flat-packed boxes. They are shipped bundled together for efficient transport and storage. Assembly is simple—just square the box, fold in the flaps, and seal with carton-sealing tape.

Are these boxes made from recycled materials, and are they recyclable after use?

Yes. These boxes are made with Kraft linerboard that typically includes 30–40% post-consumer recycled fiber. After use, remove any tape or labels and recycle them through standard corrugated recycling programs.

Can these 16x16x12 boxes be safely stacked on a pallet?

Yes. These boxes can be stacked 3–4 layers high on a standard 48" × 40" pallet, assuming contents are packed within the 40–45 lb range. Use slip-sheets or chipboard layers between tiers to improve stability for taller pallet loads.

Are these corrugated cartons safe for direct food contact?

No. While the board is non-toxic, it is not treated or certified for direct food contact. If using for consumables, insert a food-grade poly bag or liner for regulatory compliance.

Do these boxes require tools, staples, or adhesives to assemble?

No special tools are required. The boxes are pre-scored and fold easily. You’ll only need standard 2"–3" carton-sealing tape to secure both the top and bottom flaps.
