Common questions
What does ECT-32 mean and is it strong enough for my products?
ECT-32 (Edge Crush Test) indicates 32 lbs of crushing force per linear inch of flute direction. This rating is ideal for lightweight to medium-weight items like apparel, books, and artwork. It provides excellent stacking strength for palletized shipments while keeping costs competitive.
How do flat-shipped boxes reduce my fulfillment costs?
Boxes arrive flat, requiring minimal warehouse space compared to pre-assembled inventory. This reduces storage footprint by up to 90%, lowers inbound freight dimensional weight charges, and accelerates assembly during fulfillment operations, all directly improving your cost per shipment.
Can I stack these boxes during storage without crushing them?
Yes. ECT-32 kraft corrugated is engineered for reliable stacking performance. Even when stored flat in bundles, the material maintains structural integrity. Once assembled, boxes safely support multiple cartons of similar weight on pallets during warehouse operations.
Are these boxes suitable for e-commerce shipping to end consumers?
Absolutely. The shallow 2" depth reduces dimensional weight fees on UPS, FedEx, and USPS, lowering per-unit shipping costs. The kraft brown exterior projects a professional, sustainable brand image while the ECT-32 strength ensures products arrive damage-free.
