Frequently Asked Questions

These boxes feature ECT-32 single-wall corrugated, providing 32 lbs of edge crush strength per inch of thickness. This rating ensures reliable stacking performance in 4-5 high pallet configurations and protects contents during handling, transit, and storage, critical for reducing damage claims and customer returns.

By folding to the exact height needed (4", 6", or 8"), you eliminate excess void space and dimensional weight surcharges from parcel carriers like UPS, FedEx, and DHL. A warehouse consolidating five different box sizes into this one SKU typically sees 15-25% reduction in per-unit shipping spend.

No equipment required. The boxes are pre-scored at multiple depths, so workers can fold to 4", 6", or 8" height by hand in seconds. This eliminates carton sizer capital expense and allows your team to right-size boxes during order packing without slowing throughput.

One bundle of MD12128 can replace up to five traditional single-depth cartons (12124", 12126", and 12128"), reducing inventory management complexity, lowering carrying costs, and freeing warehouse shelf space, especially valuable for 3PLs and high-volume fulfillment operations.
