MeadWestvaco Offers KlaFold(R) Paperboard for Value and Performance

MeadWestvaco Corp. (NYSE:MWV) is now offering converters and
consumer products companies around the world an alternative to
lightweight coated paperboard. KlaFold, a coated unbleached kraft
paperboard manufactured by Klabin, Brazil´s largest paperboard
producer, is now available from MeadWestvaco as part of the sales and
marketing agreement the companies announced in September 2007.

With it´s unique three-ply structure, KlaFold paperboard delivers
on strength, printability and converting performance, while requiring
less fiber than competitive boards. KlaFold is particularly
well-suited for lightweight packaging applications and with its
innovative structure, KlaFold offers a higher yield at the same
caliper as most other coated paperboard in its class.

According to third-party testing conducted by Applied Paper
Technology, KlaFold has a 15-25 percent yield advantage and a
significant strength-per-pound advantage at a lower basis weight
versus most other, competitive coated paperboard grades. The tests
compared 13.4pt (220 gsm), 15.6 pt (250 gsm) and 16.9 pt (275 gsm)
KlaFold to several major competitive brands. In all cases, KlaFold had
a clear advantage with more cartons per ton of paper and greater
stiffness per pound. Tests comparing smoothness, brightness and
stiffness characteristics of KlaFold versus other paperboards also
were conducted, and KlaFold matched or outperformed the competitors
across the board.

"The testing proves what we anticipated - KlaFold delivers value
and performance," says Sean McDonald, MeadWestvaco´s manager of
strategic alliances. "It is the perfect paperboard for brand owners
who demand high shelf impact, smoothness and printability from their
lightweight packaging applications, but also want a great value."

KlaFold is an excellent choice for just about any application,
including cosmetics and personal care products, frozen foods,
electronics and much more. It also is USFDA and ISEGA compliant for
direct food contact and offers sustainability benefits of source
reduction and FSC chain-of-custody certification.

A portfolio highlighting the benefits of MeadWestvaco´s new
KlaFold paperboard is available. The portfolio includes technical and
performance information, unprinted product samples and finished
package samples that illustrate KlaFold´s excellent printing and
converting properties. To request a copy of the portfolio, contact
