DuPont Packaging Experts Show How to Cut Cost, Waste; Improve Performance, Sustainability (Pack Expo 2011)

 

WILMINGTON, Del., Sept. 8, 2011 – DuPont Packaging continued to focus its technical expertise on innovative ways to drive out cost and weight while improving performance at a Technical Exchange during PACK EXPO 2011.

Presented under the theme “Building the Future of Packaging Together,” these free sessions featured renowned DuPont packaging experts delivering technical seminars at DuPont’s suite.

“We are inviting packaging professionals to explore new tools and refresh on sealants, pealable lidding, tie-layers and polymer modifiers as a means to stimulate new ways to deliver value to brand owners and consumers,” said Barry Morris, Ph.D., DuPont senior scientist “Working together in a collaborative environment – away from the day-to-day demands – often generates new ways to take out cost and waste while improving performance for sustainable solutions that protect packaging integrity.” 

The experts were available throughout the event to exchange ideas and information at the suite. Following PACK EXPO, the presentations were available on line, inviting access globally to technical advice.

In Optimizing Flexible Packaging with Unique Tools from DuPont, Morris showcased industry- leading computer tools that help in the design of multilayer packaging structures by optimizing performance and cost while ensuring that the film or laminate can be fabricated on converting equipment.  This presentation focused on three tools for structure design: 1) selecting sealants; 2) calculating the total value in use of sealant alternatives; and 3) downgauging and life cycle analysis.

Morris also introduced DuPont™ SaVE (“Sealant Value Estimator”) in a presentation called How Much Does Your Flexible Package Really Cost?.

In Enhancing Package Performance, Value and Sustainability With Modifiers, Jose Torradas, Ph.D., DuPont Packaging senior technical consultant, shared insights into using polymer modifiers to make packaging polymers tougher and stronger, enhance their sealing properties, improve adhesion to foil or paperboard and/or increase the performance of recycled materials.

 

 

 

 

In Improving the Performance of Easy-Open Packaging, Diane Hahm, DuPont Packaging technical consultant, shared insights into several easy-open sealant solutions from DuPont.  Among those are preformulated DuPont™ Appeel® lidding sealant resins, which can meet the need for different levels of seal strength and peel mode on virtually any packaging interface, outperforming sealing lacquers while avoiding solvents and related VOC (volatile organic compound) issues.

 

 

 

 

In Surmounting the ‘Unjoinable’ Challenge, DuPont technical fellow I Hwa Lee, Ph.D., discussed how DuPont™ Bynel® coextrudable adhesive resins can strongly bond tie layers between dissimilar polymers for use in a wide variety of coextrusion processes, allowing converters to make affordable high performing packaging.
