Common questions
What's the stacking weight limit for these boxes?
With 32 ECT rating, these boxes safely stack 5-6 cartons high when fully loaded (~35 lbs each), making them suitable for standard warehouse shelving and pallet configurations without crushing risk.
How do flat-shipped boxes save costs?
Flat boxes reduce dimensional weight during shipping, lower warehouse footprint by 70%, and eliminate pre-assembly labor. A 15-pack occupies roughly 2 cubic feet versus 15+ cubic feet for pre-assembled boxes.
Are these boxes suitable for heavy products?
32 ECT corrugated is rated for moderate-to-standard duty loads (up to 35-40 lbs per box). For heavier items exceeding 40 lbs, we recommend upgrading to our 40 ECT or double-wall options.
Can I print custom logos on these retail packs?
Yes. Minimum order volumes for custom printing start at 500 units. Contact our sales team for flexographic or offset printing quotes tailored to your branding needs.
