A FRIESE Success Story

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.

Customer: Specialty Industries – Krafcor, Baltimore, Maryland
Single-facer: S&S HKE, 87″

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.
