These 20" x 12" x 12" 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
20" L × 12" W × 12" D (1.67 ft³ / 47.3 L) for high-capacity bulk packing
Yes. With a 32 ECT-C edge-crush test rating, these single-wall boxes can safely support up to 40–45 lbs when packed correctly. The larger dimensions and added height make them ideal for shipping boxed electronics, large tools, apparel bundles, household goods, or multiple smaller products packed together.
Absolutely. The 32 ECT rating meets the minimum edge-crush requirements used by major shipping carriers for standard ground delivery. For best performance, stay within the weight limit, fill void space with cushioning materials, and seal the box with strong carton tape.
ECT (Edge Crush Test) measures how much compression a corrugated board can handle at its edge. A 32 ECT board withstands 32 pounds of pressure per linear inch. The “C” flute provides a strong balance of stacking performance and impact resistance for single-wall boxes.
Each case includes 25 boxes, shipped flat and bundled for efficient storage and transportation. Assembly is simple—just square up the box, fold the bottom flaps, and apply carton-sealing tape.
Yes. These boxes are manufactured from Kraft linerboard with approximately 30–40% post-consumer recycled content. After use, remove any tape or labels and recycle the boxes through your standard corrugated recycling stream.
Yes. When packed within the 40–45 lb weight limit, these boxes can typically be stacked 3–4 layers high on a standard 48" × 40" pallet. For added stability, consider using slip-sheets or chipboard between layers and securing the stack with stretch wrap.
No. While the Kraft paperboard is non-toxic, it is not certified for direct food contact. For food applications, we recommend using a food-grade liner or poly bag inside the box.
No special equipment is required. These boxes are pre-scored for easy folding and only need standard 2"–3" wide carton-sealing tape to securely close the top and bottom flaps—no glue, staples, or strapping needed.
