PRODUCT FEATURES
Are these 20x20x12 corrugated boxes strong enough for shipping bulky or multi-piece items?
Yes. These large single-wall boxes carry a 32 ECT-C edge-crush test rating and can safely support up to 40–45 lbs when properly packed. With their broad square base and 12-inch height, they’re ideal for larger household items, bundled apparel, product kits, soft goods, or irregularly shaped items that need extra room.
Is the 32 ECT-C rating acceptable for FedEx, UPS, and USPS ground services?
Absolutely. A 32 ECT single-wall box meets the edge-crush strength standards required by all major parcel carriers for ground shipping. Ensure the box is packed with void fill or padding, sealed with strong tape, and stays under the 45 lb limit for optimal transit performance.
What does the 32 ECT-C classification mean?
ECT (Edge Crush Test) refers to the amount of pressure a corrugated board can withstand along its edge. A 32 ECT board resists 32 pounds per linear inch before collapsing. The “C” flute profile provides balanced stacking strength and shock absorption for general-purpose shipping.
How many boxes are in a case, and how are they shipped?
Each case includes 10 flat-packed boxes. Because of their larger dimensions, a lower case quantity ensures easier handling and more efficient freight packaging. Boxes ship bundled flat to save space and reduce costs.
Are these boxes made from recycled material, and are they recyclable after use?
Yes. These boxes are made from Kraft linerboard that contains approximately 30–40% post-consumer recycled content. After use, simply remove any tape or labels and recycle them through your local corrugated recycling stream.
Can these 20x20x12 boxes be stacked on a pallet?
Yes. These boxes can typically be stacked 2–3 layers high per pallet when packed within the 40–45 lb limit. Because of their large footprint, we recommend using slip-sheets or chipboard between layers and wrapping the load securely for transit.
Are these boxes suitable for direct food contact?
No. While the linerboard is non-toxic, it is not certified for direct contact with food. For food-related applications, use a food-grade poly bag or liner inside the box.
Do these boxes require special tools or adhesives to assemble?
No special tools are needed. The boxes are pre-scored for easy folding and can be assembled using standard 2"–3" wide carton-sealing tape—no staples, glue, or additional equipment required.
