and Nordmeccanica recognized with AIMCAL annual honor.
By Contributing Editor Hallie Forcinio
Dow Chemical Co. (Midland, MI) and Nordmeccanica (Hauppauge, NY) have received the 2017 Assn. of International Metallizers, Coaters and Laminators (AIMCAL) Technology of the Year Award for their jointly developed, solventless-adhesive lamination innovation. The companies were honored at a special ceremony April 26, in conjunction with ICE USA 2017 in Orlando, FL. The judges also presented two Honorable Mentions in the annual competition.
Compatible with most printing inks and substrates, the lamination technology shortens time-to-market, boosts production speeds and cuts costs. Twin coating heads on Nordmeccanica’s Duplex SL One Shot™ laminator apply one component of Dow’s two-part Symbiex™ solventless adhesive on each web. When the resin-coated and hardener-coated webs meet at the lamination nip, polymerization begins, and the adhesive quickly cures. No mixer is needed, and pot life is no longer a concern. The quick curing produces a measurable bond within 30 mins allowing quicker quality checks and slitting within 90 mins. Curing inventory is eliminated, and there’s no need for hot or thermal-conditioned curing rooms and associated energy consumption. As a result, pouches made from the lamination – even those destined for food contact – can be filled within 24 hrs instead of the typical waiting period of four to six days. In addition, final optical properties are higher, and a significant reduction in adhesive misting boosts production speeds up to 20% versus traditional solventless lamination.
The judging panel quickly acknowledged the collaborative development effort and novel nature of the resulting two-part adhesive and application technology. “Using a two-component adhesive without a Meter Mixer Dispenser really hasn’t been done before,” they agreed. “Eliminating worries about pot life is game-changing,” noted one judge. “This technology is applicable to thousands of laminators,” added another panel member.
The 2017 AIMCAL Technology of the Year Competition judging panel included five well-known experts in the converting field: Tom Bezigian of PLC Technologies (Cicero, NY); Dr. Charles A. Bishop of C.A. Bishop Consulting (Loughborough, UK); Dr. Edward D. Cohen of Edward D. Cohen Consulting, Inc. (Fountain Hills, AZ); Dr. Eldridge M. Mount of EMMOUNT Technologies LLC (Canandaigua, NY); and Dr. David Roisum of Finishing Technologies, Inc. (Neenah, WI). Craig Sheppard, executive director of AIMCAL (Ft. Mill, SC), moderated the judging teleconference.

In the Coating/Laminating Equipment/Accessories Category, the TecMaster R&D coater/laminator from Faustel (Germantown, WI), earned an Honorable Mention because it allows coating, drying and laminating experiments to be conducted using the same processes found on full-scale production equipment. The result is lower testing costs and faster turnaround due to shorter setup times. Self-contained, pre-engineered and modular in design, the unit offers a small footprint, portability and quick installation. Easily interchangeable coating heads currently include direct-gravure (unsupported with yoke), slot-die and knife-over-roll with offset-gravure and intermittent slot-die to be added this year. Options include ultraviolet and corona treaters.
“This machine provides an easy environment for research and will reduce the time needed to develop new products,” says one judge. Noting that pilot-scale equipment has not been readily available to the industry, another judge added, “The alternative is to schedule an hour on a production coater – which simply isn’t practical in many situations.”

Mylar® ovenable films won DuPont Teijin Films (Richmond, VA) an Honorable Mention in the Materials Category. First marketed in 2014, the heat-sealable, thermoformable polyesters run on automated packaging machinery and enable “no-touch” cooking. Sealed packs go from packaging line to store to home freezer or refrigerator to microwave or conventional oven for maximum convenience with minimal handling. Tailored self-venting releases steam as the product cooks/warms. The result is an entrée or meal that cooks faster and maintains taste, texture and moisture with virtually no preparation time and greatly simplified cleanup. Enhanced food safety is another benefit. Since packaging remains sealed until the food is ready to serve, risk of contamination and cross contamination is reduced substantially. Products promoting “Cooking in Mylar” have generated substantial sales in Europe, and major launches are planned in North and South America.
The judges were impressed with the heat-sealable nature of the film and the flexibility it provided for package design. They also appreciated the food safety benefits. “Moving chicken from market to fridge to oven without handling eliminates many hazards posed by touching raw proteins,” noted one member of the panel. Another judge concluded, “It makes cooking so much easier for everyone, but is especially helpful for novice cooks and small households.”
