MeadWestvaco (MWV) is now working with consumer electronics industry’s leading manufacturers like SanDisk, Lexar and others to convert packaging in retail stores worldwide from clamshells to its Natralock product.

“Consumers have been clear about their dislike for clamshells, and Natralock provides an easier-to-use solution with improved sustainability and store shelf presence,” says Jeff Kellogg, vice president of Natralock packaging, MWV.

Among other characteristics, MWV says Natralock
- Uses 60 percent less plastic on average than petroleum-based PVC clamshells
- Uses about 80 percent less energy in production
- Is made from sustainably sourced paperboard with a clear plastic APET or RPET enclosure
- The proprietary technology behind Natralock creates a high-strength, tear-resistant package that can easily be opened with scissors, leaving a smooth, safe edge and preventing the “wrap rage” commonly associated with opening traditional plastic clamshell packaging.
- Natralock is slimmer and lighter weight, which reduces warehousing space needs and transportation and shipping costs.
