Common questions
What is ECT-32 and why does it matter for my warehouse operations?
ECT (Edge Crush Test) 32 indicates the box can withstand 32 pounds of force per linear inch when compressed. This standard-strength rating is ideal for typical distribution, provides reliable stacking performance in warehouse environments, and is cost-effective for general shipping without overspecifying premium materials.
How many of these boxes fit on a standard pallet, and what's the freight advantage?
Standard pallet configuration accommodates 50-60 bundles (1,250-1,500 boxes) depending on stacking height and your warehouse racking. Flat-shipped bundles reduce dimensional weight charges compared to pre-assembled boxes, lowering your per-unit freight cost significantly.
Can I use 18x12x18 boxes for heavier products, or should I order a stronger rating?
ECT-32 handles typical mid-weight products well. For items exceeding 25-30 lbs per box or requiring extra durability, consider ECT-44 double-wall alternatives. Our team can help you match the right rating to your product weight and stacking requirements.
Are these boxes sustainable, and can my customers recycle them?
Yes, 100% kraft corrugated construction is fully recyclable and compostable. This supports your sustainability goals, appeals to eco-conscious customers, and often qualifies for favorable waste handling rates at your facility.
