PRODUCT FEATURES
Are these 20x12x8 corrugated boxes strong enough for shipping larger or heavier items?
Yes. These boxes are rated at 32 ECT-C and can safely support up to 40–45 lbs when packed properly. The generous interior space makes them ideal for shipping larger consumer goods, electronics, tools, bulk apparel, or multi-item kits that require both length and width without excessive depth.
Is the 32 ECT-C rating acceptable for FedEx, UPS, and USPS ground services?
Absolutely. A 32 ECT single-wall box meets or exceeds the strength requirements of all major shipping carriers for ground delivery. Be sure to add void fill or cushioning, secure all flaps with carton-sealing tape, and stay within the box's weight capacity.
What does the 32 ECT-C classification mean?
ECT (Edge Crush Test) measures how much edge compression a corrugated board can handle before collapsing. A 32 ECT board withstands 32 pounds of pressure per linear inch. The “C” flute is a standard profile that provides a good balance of stacking strength and shock absorption in single-wall packaging.
How many boxes come in a case, and how are they shipped?
Each case includes 10 flat-packed boxes. Because of their larger size, fewer boxes are bundled per case for easier handling and more efficient shipping. Assembly is fast—just square the box, fold the flaps, and seal with tape.
Are these boxes made from recycled materials, and can they be recycled after use?
Yes. These boxes are made from Kraft linerboard that typically includes 30–40% post-consumer recycled fiber. After use, remove any tape or labels and place the box in your standard corrugated recycling stream.
Can these 20x12x8 boxes be stacked on a pallet?
Yes. When packed within the 40–45 lb limit and arranged consistently, these boxes can be stacked 3–4 layers high on a standard pallet. To ensure stability, consider using slip-sheets or chipboard between tiers and wrap the load securely.
Are these boxes suitable for direct food contact?
No. While the material is non-toxic, it’s not certified for direct food contact. If needed for food applications, use a poly bag or food-grade liner inside the box.
Do I need tools or special adhesives to assemble the boxes?
No special tools are needed. The boxes are pre-scored and fold easily. Just use 2"–3" wide carton-sealing tape to close the top and bottom flaps securely—no staples or glue required.
