BOX USA 20x20x6 Flat Corrugated Boxes - Sturdy Shallow Shipping Box

Our review of the BOX USA 20x20x6 flat corrugated boxes finds them best suited for anyone packing light, shallow items for moving, shipping, or storage; the single biggest reason to buy is their shallow depth which fits apparel, books, frames and household items without wasted space. The cartons arrive flat to save room, are made in the USA from kraft corrugated board, and are described as heavy duty and reusable, making them a practical choice for small businesses, home moves, and long-term storage needs.

Key Features

• Shallow 6 in depth: The 20 x 20 x 6 in interior is ideal for shallow products like picture frames and folded clothing, reducing movement inside the box during transit.
• Heavy duty construction: Made from 200#/ECT-32 kraft corrugated material, these boxes are built to meet single wall shipping and storage requirements and resist crushing.
• Reusable and recyclable: The unprinted kraft brown cardboard is simple to recycle and can be reused for multiple shipments or storage cycles.
• Bulk pack convenience: Sold as a pack of 15 and shipped flat, the bundle reduces per-box cost and saves storage space in warehouses or garages.
• Made in the USA: Manufactured domestically, these cartons support local production and reduce transit distance to some sellers.

Who It's For

The BOX USA 20x20x6 box is well suited for small business owners shipping shallow goods, homeowners moving framed prints or folded clothing, and offices storing files or manuals that do not require deep cartons. Its shallow profile and sturdy single-wall construction make it a practical choice when cushioning space is limited and a neat, compact package is preferred.

Customers who need heavy-duty long-term storage for very heavy or irregularly shaped items should consider a double-wall or deeper box instead, while those seeking printed or color-coded cartons for branding may want a different product, since these are plain kraft brown and unprinted.
