Fortress™ PE paperboard is a double clay-coated bleached paperboard with an added extrusion coating of polyethylene (PE) on one (PE1S) or both (PE2S) sides. Offering a variety of polyethylene options and specifications, Fortress PE paperboard can be customized to suit your project needs. 

Available in a wide range of grades and coating weights, Fortress PE provides superior package integrity by withstanding fluctuations in temperature and moisture levels.
