These 7 x 7 x 7 inch double wall corrugated boxes are built to 275 lb burst test strength using ECT-48 double wall construction — two layers of fluted medium bonded between three liners — delivering substantially greater puncture resistance and stacking load capacity than single wall cartons of comparable size.

The equal-sided cube format suits dense or irregularly shaped products that stress standard single wall packaging: industrial components, bottled goods, ceramics, automotive parts, and similar items where box failure during transit or storage carries real cost. The flat-packed format keeps footprint minimal in receiving areas, pick lines, and high-throughput fulfillment environments.

Each box weighs approximately 0.51 lbs. and is sold in bundles of 15. The 7-inch cube dimension supports efficient palletization and helps control dimensional weight on outbound shipments. Ships via parcel.
