Starch spray system boosts strength, conserves fiber.

As U.S. paper mills and corrugated container manufactures increasingly depend on recycled fiber sources, especially for linerboard and medium grades, fiber strength becomes an important challenge. A cost effective starch spray solution that dramatically boosts paper strength while cutting fiber use showed great promise-but filter plugging problems seemed almost insurmountable. Read how new self-cleaning filters made the project work even in closed mill environments, potentially saving tens of millions of gallons per year in fresh water costs.
