This 28 x 5 x 38 inch side-loading corrugated box is constructed from ECT-32 single wall kraft corrugated board. The side-loading orientation allows contents to slide in horizontally rather than drop from the top, making it distinctly suited for items that are awkward to load vertically. Full overlap flaps provide heavy-duty edge protection.
The horizontal entry design makes these boxes a reliable choice for framed artwork, architectural drawings, foam panels, acrylic sheets, cabinet doors, and other flat or elongated goods common in manufacturing, retail distribution, and specialty e-commerce. Packing lines handling panel-format or rigid flat stock benefit from the consistent, repeatable load pattern this configuration provides.
Interior dimensions measure 28" L x 5" W x 38" H. Each box ships and stores flat, minimizing storage footprint on the packing floor. At 2.417 lbs. per unit, the weight-to-strength ratio supports practical load planning. Sold in bundles of 20 and parcel-friendly.
