Partners Brand 29173 Flat Corrugated Boxes 29x17x3 Kraft 25/Bundle

Flat Corrugated Boxes 29x17x3

These flat corrugated boxes measure 29 by 17 by 3 inches and arrive in a 25-count bundle. They are supplied new under the Partners Brand label for shipping and mailing tasks. The kraft construction provides a rigid, flat surface for packing flat or shallow items.

Practical limits of flat corrugated construction

The three-inch depth restricts use to slim contents such as documents, framed prints or thin electronics. Corrugated kraft offers crush resistance but no moisture barrier, so wet environments require additional wrapping. The fixed 29 by 17 footprint cannot accommodate oversized or irregular loads.

Quick assembly with tape, watch for crease alignment

Each box ships flat and folds into shape in seconds using packing tape along the seams. Misaligned creases are the most common issue and can leave gaps at the corners. Applying even pressure while taping keeps the structure square and prevents the bottom from bowing under weight.
