Common questions

What does ECT-32-B mean, and why does it matter for my shipments?
ECT (Edge Crush Test) 32-B indicates the corrugated can withstand 32 pounds of pressure per linear inch when crushed from the edge. This rating ensures reliable protection for lightweight items during multi-unit stacking and provides durability compared to lower ECT grades, reducing damage claims and customer returns.
How much assembly time do these one-piece mailers save versus traditional boxes?
Fold-and-tuck mailers assemble in 2-3 seconds per unit with zero additional materials needed, no tape guns, glue, or staples required. A fulfillment team can pack 500-1,000 units per hour compared to 200-300 with traditional taped boxes, directly improving throughput and labor efficiency.
Will these mailers protect fragile items without additional void fill?
Yes. The double-wall corrugated construction on the front and sides provides inherent crush resistance suitable for most small fragile items. However, we recommend lightweight tissue or kraft paper for added protection of delicate goods like glassware or electronics to minimize transit damage.
What's the per-unit cost advantage of ordering in bundles of 50?
Bundled packaging reduces our production and fulfillment overhead, allowing us to pass savings directly to you. Bundle purchases also minimize per-unit dimensional weight in your outbound freight, cutting overall logistics costs on large volume orders when compared to smaller case quantities.
