Common questions

What is ECT-32-B corrugated, and why does it matter for my shipping operation?
ECT (Edge Crush Test) 32-B indicates a 32 PSI crush rating on B-flute corrugated, the industry standard for lightweight parcel shipping. It balances strength and material cost, protecting contents without adding postage-inflating weight. Use for small, non-fragile items and volume-driven fulfillment.
How much faster is fold-and-tuck assembly compared to tape-sealed boxes?
One-piece mailers fold in 2-3 seconds per unit with zero consumables (no tape, glue, or staples). For a 1,000-unit daily volume, this saves 30-50 labor minutes and eliminates ongoing tape/adhesive costs, direct impact to fulfillment efficiency metrics.
Will ECT-32-B protect fragile items, or do I need a heavier grade?
ECT-32-B provides reliable crush resistance for lightweight fragile goods (electronics, cosmetics, books, samples) via double-wall construction. For heavier or high-stack scenarios, consider ECT-44 or ECT-48. Evaluate your specific item weight and stacking requirements.
Can these mailers be customized with my logo or branding?
Standard white mailers ship plain. Custom printing (1-4 color) is available on larger order volumes. Contact our sales team for quoted lead times and minimum order quantities for branded packaging.
