20 x 12 x 3" Flat Corrugated Boxes

This 20 x 12 x 3 inch corrugated box is a shallow-depth RSC box built specifically for flat and low-profile items. The 3 inch interior depth reduces excess void fill and helps control dimensional weight charges that deeper cartons would introduce.

The shallow format suits e-commerce apparel fulfillment, framed prints and documents, retail catalog distribution, and light industrial kitting — any application where a standard-depth box adds unnecessary bulk. The flat-pack format stacks compactly on packing floors and warehouse shelving, keeping floor space clear until cartons are needed.

Each box is constructed from ECT-32 single wall kraft corrugated, delivering reliable stacking strength and puncture resistance at approximately 0.69 lbs. Boxes are sold in bundles of 25 and ship via parcel carrier.
