Water Based Barrier CoatingsLeading the future use of paper

PaperCon 2011 Page 1028

OVERVIEW

• Purpose: Review the use of barrier coatings for paper packaging both now and in the future

• Considerations/Factors- Drivers – traditional and water based materials- Needs - performance, environmental, regulatory- Practices – materials, application, converting - Future trends

• Payoff: Lead the future use of paper for barrier applications.

PaperCon 2011 Page 1029

Put simply…

Coatings improve the performance of paper

and packaging performance.
