PRODUCT FEATURES
Are these 20x8x8 corrugated boxes strong enough for shipping long, lightweight products?
Yes. These long rectangular boxes have a 32 ECT-C edge-crush test rating and support up to 40–45 lbs when packed correctly. Their slim profile is ideal for items such as rolled posters, lighting fixtures, metal rods, tools, small tripods, auto parts, and bundled product kits that require extra length without much depth.
Is the 32 ECT-C rating acceptable for FedEx, UPS, and USPS ground services?
Definitely. A 32 ECT single-wall box meets the minimum edge-crush strength required by major shipping carriers for standard ground service. Be sure to protect the contents with void fill or foam and seal the flaps tightly using high-quality tape.
What does the 32 ECT-C classification mean?
ECT (Edge Crush Test) measures the pressure a corrugated board can withstand along its edge. A 32 ECT board resists 32 pounds per linear inch of edge pressure before failing. The “C” flute refers to a medium-depth fluting pattern that balances stacking strength and cushioning.
How many boxes are in a case, and how are they shipped?
Each case contains 25 flat-packed boxes. They’re bundled compactly to reduce shipping costs and save space in your facility. Assembly is quick—just fold the flaps and secure with standard carton-sealing tape.
Are these boxes made with recycled content, and can they be recycled after use?
Yes. These boxes are constructed from Kraft linerboard that typically contains 30–40% post-consumer recycled material. Once used, remove any tape or labels and recycle the boxes through your local corrugated recycling stream.
Can these 20" long boxes be stacked on a pallet?
Yes. These boxes can be stacked in 3–4 layers on a standard 48" × 40" pallet, provided the weight limit (40–45 lbs per box) is not exceeded. Due to the narrow width, we recommend alternating or interlocking rows and using slip-sheets or chipboard between layers for stability.
Are these boxes food-safe for direct contact?
No. While the boxes are made from non-toxic materials, they are not FDA-certified for direct food contact. For food use, insert a poly bag or liner to meet compliance standards.
Do I need tools or special adhesives to assemble the boxes?
No tools are required. These boxes are pre-scored and fold easily by hand. Just use 2"–3" wide carton-sealing tape to close the top and bottom flaps—no glue, staples, or equipment needed.
