Common questions
What does ECT-32-B mean, and how does it compare to other corrugated grades?
ECT (Edge Crush Test) 32-B indicates a 32 lb/in crush rating with B-flute corrugation. This mid-range grade balances strength and weight, ideal for small parcel protection without excess material cost. Use for lightweight items under 10 lbs; heavier products may require ECT-40 or higher.
How many boxes fit on a standard pallet, and what's the dimensional weight impact?
Approximately 2,000, 2,400 bundles (100,000, 120,000 individual boxes) fit per pallet when stacked efficiently. At 8x5x4", these mailers optimize DIM weight calculations, reducing per-box freight charges by 15, 25% versus oversized alternatives.
Do these mailers require tape or glue to seal?
No. The one-piece fold-and-tuck design self-seals without tape, glue, or staples. This reduces assembly labor by 40%+ and eliminates material waste, lowering operational costs significantly in high-volume environments.
Are these boxes suitable for hazmat or heavy items?
No. ECT-32-B is rated for lightweight items (typically under 10 lbs). For fragile or heavy shipments, upgrade to ECT-40 or higher-rated corrugated. Always verify weight limits before ordering to ensure compliance and damage prevention.
