The BSC PREFERRED SP4042TW is a triple wall corrugated sheet designed to protect heavy machinery, appliances, and industrial goods during storage and transit. Manufactured from 1100TW/ECT-90 kraft corrugated board, each sheet measures 40 x 42 inches and delivers the high crush resistance needed to withstand forklift traffic and stacked load pressure. These sheets are placed between layers of product to absorb impact and distribute weight. They are sold in cases of 5 sheets. Warehouse teams, freight handlers, and packing professionals use them as layer pads in pallet configurations or as protective slip sheets in heavy-duty packaging operations.
These corrugated sheets are suited for industrial and commercial packaging environments where standard single- or double-wall board is insufficient. Common applications include layer separation in pallet loads of equipment, machinery components, HVAC units, water heaters, and other heavy goods. The 40 x 42 inch footprint is sized to accommodate standard pallet dimensions, making them a practical fit for distribution centers, manufacturing facilities, and warehousing operations that require consistent protective layering across high-volume shipments.
Designed as a general-purpose triple wall layer pad for use between heavy machinery, appliances, and industrial equipment in standard pallet packaging configurations.
Place sheets flat between each product layer on a pallet, ensuring full coverage of the layer surface before adding the next tier of goods. No tools are required. Inspect each sheet for damage before use, as compromised board reduces load protection. Follow your facility's packing and stretch-wrap procedures to maintain load stability during transport.
