Common questions
What is ECT-32 and why does it matter for my shipping operation?
ECT (Edge Crush Test) 32 indicates the box can withstand 32 lbs of force per linear inch, ideal for single-wall applications where moderate stacking and handling are expected. This rating balances durability with cost-efficiency for mid-weight tall items, reducing packaging spend without sacrificing product protection.
Can I stack these boxes on pallets without collapse?
Yes. ECT-32 single-wall construction supports multiple-tier stacking in warehouse environments. Stack height and weight distribution depend on your specific products; contact our packaging experts for load-testing recommendations based on your SKU weight.
How do these boxes compare to mailing tubes for long items?
These corrugated boxes offer cushioning, easier labeling, and better dimensional weight performance on parcel carriers. Unlike tubes, they provide full product enclosure, reduce void-fill material needs, and enable faster automation in fulfillment centers.
What order volume qualifies for bulk pricing and faster delivery?
Packrift offers tiered pricing on case quantities and full-pallet orders (typically 45-50 bundles). Contact our B2B sales team for custom quotes, freight consolidation options, and expedited shipping rates based on your monthly volume projections.
