Common questions
What does ECT-32 mean and is it strong enough for my products?
ECT-32 (Edge Crush Test 32 lbs/in) is single-wall corrugated rated for approximately 23 lbs static stacking strength. It's ideal for lightweight to mid-weight items like apparel, books, and frames. For heavier products, consider ECT-44 or double-wall options.
How much can I save on dimensional weight shipping with the 4" depth?
The shallow 4" depth eliminates wasted dimensional space compared to standard 6" or 8" boxes. Most carriers calculate DIM weight at 166 cubic inches per pound; this box totals 1,024 cubic inches (6.2 lbs DIM equivalent), reducing surcharges on lightweight shipments significantly.
Can I order partial bundles or different quantities?
This product is sold in bundles of 25. For volume pricing on larger orders or custom quantities, contact our B2B sales team. Bulk orders of 500+ boxes often qualify for additional discounts.
Are these boxes recyclable and compostable?
Yes. ECT-32 kraft corrugated is 100% recyclable through standard curbside and industrial recycling programs. The natural kraft material is also compostable in commercial facilities, supporting circular economy initiatives.
