Common questions
What does ECT-32 mean, and is it strong enough for my shipping needs?
ECT-32 (Edge Crush Strength of 32 lbs/inch) is ideal for standard industrial shipping, small-to-medium parcels, and general warehouse storage. It provides reliable stacking strength for 3-4 tier pallets, making it cost-effective for most B2B fulfillment operations without overspecification.
How many boxes can I stack, and what's the maximum weight limit?
ECT-32 single-wall corrugated typically supports 3-4 boxes stacked when properly filled. Maximum load capacity depends on box contents and storage conditions; we recommend testing with your specific products to ensure optimal performance and safety.
Will these boxes fit standard pallet dimensions for freight efficiency?
Yes. The 18.5" x 18.5" footprint is designed for efficient pallet loading, allowing 4 boxes per layer on a standard 40" x 48" pallet. This maximizes cube utilization and reduces per-unit freight costs compared to oversized boxes.
Are these boxes environmentally compliant and recyclable?
Absolutely. Our kraft corrugated boxes are 100% recyclable and made from sustainable materials. They meet environmental standards for eco-conscious shippers and support corporate sustainability goals while maintaining performance and cost efficiency.
