Verbatim stands behind the quality of our products--we’ve done so for over 40 years!, Consumers choose to spend their money in more eco-conscious ways, and Verbatim gives them the option to get high-tech without being highly wasteful. Verbatim’s new packaging for USB drives and Memory Cards is greener than ever. Our new package design reduces the amount of plastic used by up to 93.9% on Memory Cards and 90.9% on USB drives by substituting paperboard material for the plastic clamshell. Now, the only plastic part of our packaging surrounds the product, thus optimizing the use of renewable resources and keeping un-necessary plastic out of landfills. Material Components The paperboard structure is MWV Natralock™ material. This offers greater sustainability and also greater security and safety than a traditional clamshell package. A tear-resistant layer requires scissors to open but won’t cut the consumer with sharp edges. These packages offer additional benefits that are a side-effect of going green. They are designed to withstand over 25-lbs. of downward pressure without tearing--which also ensures the packaging cannot be torn off a display hook. Verbatim used this redesign opportunity to eliminate the plastic case previously included with Memory Cards. Since most consumers discarded the case, all unnecessary elements have been eliminated., More Green Packaging Benefits Verbatim now adds an icon to packaging meeting our “More Green” standards; we want to highlight the environmental benefits of this new packaging structure to customers and the industry alike. Look for the “More Green” logo on Verbatim products as well as the specific benefits on the back., *2009 COMPASS analysis of packaging material systems. Results differ by procut.
