Common questions
What does ECT-32 mean and why does it matter?
ECT-32 refers to Edge Crush Test rating of 32 pounds per inch, a standard for single-wall corrugated. This provides reliable stacking strength for mid-weight products while maintaining cost efficiency. For shallow boxes like these, ECT-32 delivers optimal protection-to-cost ratio for B2B shipping volumes.
How does the shallow 4-inch depth reduce my freight costs?
Carriers charge based on dimensional weight (length x width x height / 166). The 4-inch depth minimizes cubic footage per shipment, lowering DIM weight charges significantly compared to standard-depth boxes. When multiplied across thousands of monthly shipments, this creates substantial volume savings.
Can these boxes handle stacking in a warehouse environment?
Yes. ECT-32 single-wall construction supports reliable stacking performance typical of retail-weight merchandise. Stack height depends on product weight, but these boxes are engineered for standard warehouse vertical storage of lighter items like apparel and books.
What products work best in a 20x12x4 box?
This size is optimized for apparel, books, magazines, picture frames, artwork, mirrors, and similar shallow merchandise. The dimensions minimize wasted space while providing 960 cubic inches of volume, making it ideal for e-commerce fulfillment where every square inch impacts logistics costs.
