These 40 x 42 inch triple wall corrugated sheets are built from ECT-90 kraft corrugated board, delivering heavy-duty compression strength and puncture resistance that single wall and double wall materials cannot match. The triple wall construction provides exceptional rigidity and load-bearing capacity at approximately 3.86 pounds per sheet.

At this size, these sheets are well-suited to standard pallet configurations and see regular use as layer pads between stacked pallets, protective slip sheets in heavy freight shipments, crating reinforcement for machinery and industrial equipment, and structural damage barriers in warehousing, manufacturing, and distribution environments.

Constructed from kraft corrugated board rated ECT-90, each sheet meets the demands of high-compression industrial applications. Sheets are sold in bundles of 5.
