Common questions
What does ECT-32 mean and how does it compare to other corrugated strengths?
ECT (Edge Crush Test) 32 indicates the box can withstand 32 lbs of force per linear inch of edge crush, ideal for moderate-weight items and standard stacking applications. ECT-32 single-wall construction balances cost efficiency with reliable protection, making it the industry standard for mid-range shipping volumes.
Can I use these 6x6x38 boxes instead of mailing tubes for posters and blueprints?
Yes. The 6 x 6 x 38" tall box offers protection compared to standard mailing tubes while providing better stacking performance and freight efficiency. The end-loading design makes insertion simple, and kraft corrugated resists crushing better than tube alternatives.
How many boxes fit on a standard pallet and what's the freight advantage?
Approximately 120 - 150 flat-packed bundles (3,000 - 3,750 individual boxes) fit on a 48x40" pallet, depending on stacking height. Flat packaging reduces dimensional weight by 70 - 80% versus pre-assembled boxes, directly lowering your per-unit freight costs on LTL and parcel shipments.
Are these boxes rated for stacking in a warehouse environment?
Yes. ECT-32 single-wall corrugated is rated for standard warehouse stacking (typically 4 - 6 boxes high when fully loaded). Always verify your specific load weight with our packaging specialists to confirm stack height for your application.
