MWV Introduces Tear Test Specification Grades to Increase Security Options for its Natralock® Packaging



Richmond, VA (September 25 2008) - Global packaging solutions leader MeadWestvaco Corporation (NYSE: MWV) has introduced three grades for its Natralock® Security Packaging to give customers and brand owners greater flexibility surrounding their desired level of product security and brand protection. Natralock packaging is offered in three different tear-resistant grades along with a variety of substrate selections, including MWV Printkote® SBS, Printkote Eagle®, Custom Kote® CNK®, and Kraftpak®.

"Natralock's outstanding strength and durability ensures the highest quality trap seal blister packaging solution that spans a wide array of applications," said Jeff Kellogg, vice president, Natralock security packaging, MWV. "As such, our customers require different levels of security, so a 'one-size-fits-all' option isn't ideal. By providing a choice of substrate grades we're allowing customers to incorporate the appropriate levels of security features into their packaging as the product requires."

All solutions obtain the ideal performance for fold-over or two-piece trap seal blister card applications where added pilfer resistance is desired. The three levels of tear-resistant substrate grades include:

o Natralock® ETR is engineered for applications requiring the Elmendorf tear test specification. The tear strength of the paperboard remains constant even after a tear has been initiated.

o Natralock® GTR is developed for items required to meet specifications established by the Graves tear test method. The paperboard is extremely difficult to tear without first initiating a nick with a sharp object and utilizes a special construction for a better consumer experience.

o Natralock® NTR features MWV's Easy Seal® technology and offers only the substrate's inherent tear properties. This provides the most economical solution for non-secure products and applications.

Natralock security packaging is specifically engineered to be used as a clamshell replacement package to deter theft, increase product and brand security and enhance environmental sustainability objectives. Natralock packaging starts with a theft-resistant, laminated paperboard that is recyclable, and is then combined with a clear APET or RPET thermoform to create a visible package that uses 50 to 60 percent less plastic on average than traditional PVC clamshells and is nearly impossible to tear apart by hand. However, a consumer can safely and easily open the Natralock package with a pair of household scissors, avoiding "wrap rage" and the often injurious struggle consumers experience with clamshells.
