, Ann Arbor, MI; 734/622-6000
Matrix UV ink systems are based on a newly developed, proprietary resin chemistry said to produce impenetrable bonds and to result in inks that deliver faster cure speeds, improved gray balance, and enhanced ink/water latitude for faster makereadies and easier runnability. Systems are designed to help web- and sheet-fed printers shorten turnaround times and increase pressroom efficiency. The line consists of a variety of products specially formulated for specific packaging applications. Ink systems are available in process and Pantone colors as well as in UV-coatable colors.

Resin Enhances Adhesion to Foil, Metallized Film
Dupont Packaging
, Wilmington, DE; 800/438-7225
DuPont Nucrel AE resin for extrusion coating and extrusion laminating is said to enhance adhesion to aluminum foil and metallized film when blended into LDPE. Benefits are said to include increased line speed without sacrificing adhesion to metal; improvement in heat seal and hot-tack performance compared to LDPE alone; and decreased process temperatures for improved taste and odor. Resins can be used in snack and dry food structures and in other foil-containing pouches and sachets for non-aggressive products. Also can be used in non-packaging applications such as industrial coatings.
