Common questions
What does ECT-48 mean and why does it matter?
ECT-48 (Edge Crush Test) indicates 48 pounds of pressure required to crush the carton edge, signifying heavy-duty construction. This rating ensures maximum protection for high-value shipments and performance under pallet stacking conditions.
How much weight can these boxes safely stack?
Double wall ECT-48 construction supports aggressive stacking for full pallet loads in warehouse environments. Actual stacking capacity depends on box fill weight and storage duration; contact our team for load calculation assistance.
Why buy flat-shipped bundles instead of pre-assembled boxes?
Flat shipping reduces freight class and dimensional weight charges by up to 65% compared to assembled cartons, lowering your total landed cost. Easy assembly takes seconds per box, and flat storage requires 80% less warehouse space.
Can I order different quantities beyond bundles of 5?
Standard inventory ships in bundles of 5 for maximum freight efficiency. For bulk orders or custom quantities (25+), contact our B2B sales team for volume pricing and dedicated logistics support.
