Common questions
What is ECT-32-B and why does it matter for my shipping operation?
ECT-32-B (Edge Crush Test 32) is the corrugation grade that measures how well stacked boxes resist crushing force. ECT-32-B provides optimal strength-to-weight ratio for small parcel shipping, ensuring fragile items stay protected while keeping postage costs low, critical for volume-based shipping operations.
How much labor and material do I save with one-piece, fold-and-tuck design?
One-piece mailers eliminate tape, glue, staples, and multi-step assembly. Warehouse staff can fold and tuck each mailer in seconds, reducing labor per unit by 40-60% versus traditional box assembly. This translates to faster fulfillment cycles and lower per-unit packaging costs at scale.
Are these mailers suitable for stacking in a warehouse environment?
Yes. When folded, these mailers maintain their structural integrity and stack efficiently on pallets. The ECT-32-B corrugated material supports moderate stacking loads typical of fulfillment centers, though stacking should follow best practices to avoid compression of contents.
Can I use 8 x 5 x 5" mailers for heavier items?
These mailers are optimized for lightweight items (fragile goods, small electronics, apparel). For heavier shipments, upgrade to higher ECT ratings (ECT-44 or ECT-48). Always verify weight limits and conduct void-fill testing to ensure items remain protected during transit.
