We further differentiate our white top offerings by providing specialty grades such as premium, coated, wet-strength and waxable white top.

Coated White Top
Coated white top is designed to offer ultimate flexibility for high graphics users, with the ability to generate high-print gloss and ink density. It is post-printable without the aid of dryers, yet suitable for the demands of preprinters. Our lightly coated white top offers superior runnability and convertibility, with the compression strength of regular white tops.

Solid Bleached Linerboard
Solid bleached linerboard is ideal for displays or premium packaging due to its uniform appearance and brightness (80). Our regular hold-out bleached linerboard is a single-ply sheet of bleached fibers produced with moderate calendaring and a surface treatment to promote optimal ink hold-out. It's ideal for line art and solid coverage printing.
