Flat Box Buying Guide

What Are Flat Boxes Used For?

Flat boxes (also called low-profile boxes or shallow boxes) are corrugated shipping cartons with reduced depth dimensions. They're engineered for products that don't require standard box heights, providing a snug fit that prevents shifting during transit while reducing dimensional weight shipping costs.

What Size Flat Box Do I Need?

Measure your product at its flattest packed state. Add 1/8" to 1/4" on length and width for comfortable fit. Choose the smallest depth that accommodates your item plus any cushioning material. Common flat box depths range from 1" to 4".

Are Flat Boxes Cheaper to Ship?

Yes! By minimizing unused vertical space, flat boxes reduce dimensional weight charges from carriers. This can save 20-40% on shipping costs compared to using standard-height boxes for shallow items.

Can Flat Boxes Be Recycled?

Absolutely. Our kraft corrugated material is 100% recyclable and biodegradable. Many flat boxes are made with recycled content, supporting sustainable packaging practices.

What's the Difference Between ECT-32 and 200# Test?

Both ratings indicate box strength. ECT-32 (Edge Crush Test) measures stacking strength - these boxes can handle 32 lbs per inch of stacked weight. The 200# burst test measures puncture resistance. Our flat boxes meet both standards for reliable protection.
