Common questions
What does ECT-32-C corrugated mean, and why does it matter?
ECT-32-C indicates 32-ECT (Edge Crush Test) kraft corrugated with C-flute, delivering industry-standard durability for most shipping applications. This specification ensures your products arrive damage-free while maintaining cost efficiency, ideal for e-commerce operations managing margin pressure.
How does multi-depth scoring improve my shipping workflow?
Pre-scored fold lines allow you to adjust mailer depth from minimal (thin items) to full 6" capacity without changing products or SKUs. This flexibility reduces inventory complexity and packaging waste while accommodating variable product dimensions on a single production line.
Are these mailers suitable for fragile items?
Yes. ECT-32-C construction provides excellent puncture and compression resistance. For extremely fragile items, pair with internal cushioning materials. The rigid one-piece design prevents crushing better than competing foldable alternatives.
What's the environmental impact of choosing kraft jumbo mailers?
Kraft corrugated is 100% recyclable and typically contains 80%+ post-consumer recycled content. Choosing properly-sized mailers reduces excess material waste and shipping weight, lowering your carbon footprint while improving your e-commerce brand's sustainability story.
