FlatStack original tier sheets

Made from 100% recycled fibers and completely recyclable, FlatStack paperboard sheets are a cost-effective solution that protects products on pallets during shipping, storage and retail display.

Compared to typical corrugated tier sheets, FlatStack sheets offer a minimum 5% reduction in weight and generally garner a minimum of 15% cost savings across the supply chain.

They also offer 5 times the amount of sheets per unit storage, and more than twice as many sheets shipped per truckload:
