PRODUCT FEATURES
Are these 12x12x12 corrugated boxes strong enough for shipping bulkier or fragile items?
Yes. These cube-style boxes feature a 32 ECT-C edge-crush test rating, offering dependable strength for shipping a wide variety of items. When packed with protective materials, they can safely support up to 40–45 lbs—ideal for shipping things like electronics, mechanical components, household items, and even multiple smaller products grouped together.
Is the 32 ECT-C rating acceptable for FedEx, UPS, and USPS ground services?
Absolutely. A 32 ECT single-wall corrugated box meets the minimum strength standards required by all major ground shipping carriers. Just ensure proper packing with void fill, seal with quality tape, and do not exceed the recommended weight limit.
What does the 32 ECT-C classification mean?
ECT (Edge Crush Test) measures the board’s edge-compression resistance. A 32 ECT board can withstand 32 pounds of pressure per linear inch. The “C” flute refers to the most common corrugated profile, offering good cushioning and stacking strength in a single-wall construction.
How many boxes come in a case, and how are they shipped?
Each case includes 25 boxes, shipped flat and banded together for cost-efficient freight and minimal storage space. To assemble, square the box, fold the bottom flaps, and secure with carton-sealing tape.
Are these boxes made from recycled material, and can they be recycled after use?
Yes. These boxes are constructed from Kraft linerboard that typically contains 30–40% post-consumer recycled content. They’re fully recyclable—just remove tape or labels before placing in your local corrugated recycling stream.
Can these 12-inch cube boxes be safely stacked on a pallet?
Yes. With proper packing and within the 40–45 lb per-box limit, these boxes can typically be stacked 4–5 layers high on a standard 48" × 40" pallet. Use slip-sheets or chipboard between layers for added load stability when stacking higher.
Are these boxes suitable for direct food contact?
No. While the material is non-toxic, it is not FDA-approved for direct food contact. For shipping food products, we recommend using a food-grade liner or poly bag inside the carton.
Do I need any special tools, glue, or staples to assemble these boxes?
Not at all. These boxes are pre-scored for easy folding and only require standard 2"–3" wide carton-sealing tape for secure closure—no additional equipment is necessary.
