Common questions

What does ECT-32-B rating mean for my shipping operations?
ECT (Edge Crush Test) 32 indicates 32 lbs per inch of crush strength, sufficient for 4-5 high carton stacking. This rating optimizes pallet density while maintaining structural integrity during warehouse handling and transit, reducing damage claims on light-to-medium shipments.
How many mailers can I fit on a standard pallet?
Flat-packed bundles of 50 allow 100+ bundles (5,000+ units) per 48x40" pallet, maximizing your warehouse storage efficiency and reducing per-unit shipping costs on bulk orders.
Can these mailers be customized with branding?
Yes, M442 mailers accept flexographic and digital printing for company logos, messaging, and product information. Contact our sales team for minimum order quantities and lead times on custom print orders.
How much faster are these versus traditional tape-and-box assembly?
Fold-and-tuck design reduces packing time by 60-70% compared to tape-sealed cartons, your team can pack 40-50 units per hour per worker with zero adhesive waste and faster throughput on high-volume orders.
