MULTIPLY
More layers. More strength.
MULTIPLY is a multi-ply heavy-duty kappa board engineered for industrial, export, and protective packaging applications requiring maximum thickness and compression strength.
Engineered for performance
MULTIPLY is our heaviest-duty board — a multi-ply construction that delivers exceptional thickness, compression strength, and rigidity for the most demanding packaging applications.
Available in thicknesses from 2.0 mm to 6.0 mm and grammages from 1200 to 2500 gsm, MULTIPLY is the board of choice for industrial packaging, heavy export cartons, and protective packaging for large or heavy products.
The multi-ply construction ensures consistent caliper and structural integrity across the full sheet, even at the highest thicknesses.
