12 x 10 x 4" Heavy-Duty Boxes

These 12 x 10 x 4 inch heavy-duty corrugated boxes are manufactured from ECT-44 single wall kraft corrugated board, delivering approximately 40% greater compression and stacking strength than standard ECT-32-C cartons. The elevated edge crush test rating makes these boxes well-suited for heavier contents, stacking under load, and shipments where product protection during transit is a priority.

The shallow 4 inch depth suits flat and low-profile items including apparel, documents, framed prints, electronic accessories, and retail-ready packaged goods. E-commerce fulfillment centers, regional distributors, and manufacturing packaging lines all benefit from the reinforced construction when standard single-wall cartons fall short.

Each box weighs approximately 0.58 lbs and ships flat for compact storage in bundles of 25.
