A FRIESE Success Story
In August 2008 SHARP International oversaw the installation of a new set of FRIESE C-flute corrugating rolls at Krafcor of Baltimore, Maryland. Krafcor saw immediate results.

Combined board samples were taken prior to and after installation of the new corrugating rolls.
The same rolls of linerboard and medium were quarantined and used for the before and after combined board samples.
