Flat Corrugated Boxes for Shallow & Low-Profile Products

Flat corrugated boxes combine a larger length-and-width footprint with a shallow depth for books, apparel, printed materials, artwork, parts, and other low-profile products.

How to Choose

1. Measure the product's largest flat dimensions.

2. Add room for edge and surface protection.

3. Avoid excessive depth when a shallower carton fits the application.

4. Choose strength for the complete shipment.

Choosing Flat Corrugated Boxes

Flat corrugated boxes work well for products such as printed materials, books, apparel, frames, artwork, panels, and shallow parts when a conventional carton would leave too much vertical space. The goal is a close depth without compressing the product. Edge protection, surface protection, and bending resistance may be as important as box strength for flat shipments. Match the carton footprint to the protected product.

Choose a shallow height that fits the product and required interior protection. Use pads, sheets, wrap, or other protection where abrasion, bending, or edge damage is a concern. Evaluate box construction based on product weight and handling. Use the current product table and individual item details to confirm available sizes, materials, quantities, and specifications for the exact item you are considering.

Frequently Asked Questions

What are flat corrugated boxes used for?

They are useful for shallow products such as books, printed materials, apparel, artwork, frames, and low-profile parts.

Can a flat box help with dimensional weight?

A closer-fitting shallow carton may reduce package dimensions compared with an oversized box, but carrier charges depend on the completed package and current rules.

Should I use a flat box or a corrugated mailer?

Choose based on product fit, closure style, presentation needs, packing process, and the available dimensions.

How do I choose box strength?

Consider product weight, carton dimensions, stacking, handling, interior protection, and the listed corrugated construction.
