The Unit Pack is manufactured with assorted films, produced from resin and additives which comply with the U.S. Food, Drug and Cosmetic Act for packaging of foods and pharmaceuticals. The flexible packaging film is available in crystal clear and sparkling white. The film color is pigmented throughout the plastic, not just on the surface. It will not scratch, smear or rub off. A very thin, high barrier 6 mil. film protects the integrity of your product from oxygen, water and oil assuring long shelf-life and customer satisfaction.
