The wet strength of MeadWestvaco's Coated Natural Kraft
(CNK)[R] paperboard keeps the package from losing its integrity during the various stages of the product's life.
grocery stores, researchers found that Coated Natural Kraft
(CNK) paperboard had the least incidence of damage on freezer shelves, compared to packaging made with other paperboard-based materials.
A further advantage is that the Coated Natural Kraft
guarantees pack performance during deep freeze processing, storage and distribution.
This group is comprised of the bleached paperboard mills in Evadale, Texas, and Covington, Virginia, the coated natural kraft
mill in Cottonton, Alabama, and the unbleached paper mill in North Charleston, South Carolina.
