Neenah Paper Gives Retailers 'Green' Option: Neenah Paper now offers the new ENVIRONMENT Retail Card, a 100-percent, paper-based stored value card that gives retailers a green alternative to plastic or other less eco-friendly card options. The new retail card is also the brightest paper-based card available. A stored-value card has monetary value or data physically stored on the card and is commonly used by retailers in the form of gift cards, loyalty cards and bounce-back cards.
