Common questions
What does ECT-32 mean and is it strong enough for my shipments?
ECT-32 (Edge Crush Test) indicates 32 pounds per inch of crush strength, the industry standard for single-wall corrugated. It's proven for general shipping, e-commerce fulfillment, and moderate-weight products. For heavier items or double-wall requirements, consider upgrading to ECT-44 or ECT-48 ratings.
How many boxes do I need to order, and what's the minimum?
This product is sold as a bundle of 25 boxes. For volume discounts and custom quantities, contact our sales team. Ordering in bundles reduces per-unit costs and freight efficiency for larger operations.
Can these boxes be stacked safely in a warehouse?
Yes. ECT-32 kraft boxes stack reliably under normal warehouse conditions when properly loaded. Stack height depends on product weight inside, heavier loads require lower stacks. Always test stacking performance with your specific product weight to ensure stability.
Are these boxes eco-friendly and recyclable?
Yes, kraft corrugated is 100% recyclable and made from renewable fiber sources. Using these boxes supports your sustainability goals while meeting customer expectations for environmentally responsible packaging in your supply chain.
