These 12" x 12" x 6" cartons are engineered from single-wall, C-flute corrugated kraft board with a certified 32 ECT (Edge-Crush-Test) rating, giving packers a strong yet lightweight shipping option. The material offers:
32 ECT compliant—capable of withstanding ≈32 lb per linear inch of edge load before failure
Up to 40 lb (18 kg) of evenly distributed contents for typical parcel and LTL shipments
12" L × 12" W × 6" D (0.5 ft³ / 14.2 L) for efficient flat-item packing
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.
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.
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.
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.
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.
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.
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.
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.
