It may seem like too little and too late, but the Food and Drug Administration recently issued its 1993 revision of "Standards for the Fabrication of Single Service Containers and Closures for Milk and Milk Products." Federal and state regulatory inspectors use these standards as the basis for inspecting plants manufacturing dairy packaging.
Custom packaging played a key role in the success of a recent hair-care product promotion by Matrix® Essentials of Solon, OH. The firm's Vavoom(TM) and Systeme Biolage® professional salon hair-care product lines were offered in a special 250-mL promotional size.
