US-based Cerealus has extended its product portfolio of additives with the launch of the new Cerefiber for paper and packaging mills.
The new product is said to allow mills to increase bond or tensile strength, which can enable material reductions in basis weight, increased stiffness, less pulp refining or further optimization of less expensive furnish.
Built with a starch encapsulation technology, the company’s Cerefiber can treat every form of pulp fiber, including recycled fiber, chemical pulp, semi-chemical, and groundwood, while maintaining specified strength as well as paper qualities.
The technology will direct the starch to attach to the fiber without impacting machine chemistry, charge or BOD.
Cerealus’s Cerefiber allows mills to reduce fiber and achieve bond and tensile strength of over 40%.
The mill users that use Cerefiber technology include various paper products, such as newsprint, coated free sheet, uncoated free sheet and coated groundwood.
With new Cerefiber, mills can increase all forms of filler by 5-10 % points.
