PROCITE envelope window film combines both the optical and physical performance required for high performance OCR readability of text characters and bar codes, allowing for almost 100 percent sorting efficiency. The film also provides security by providing the finest level of haze to prohibit third-party reading of personal information beyond the address block area.

"Readability and security are just a few of the many positive attributes customers gain from using PROCITE film," said Jo Watkins, global marketing manager, Dow Postal Films. "All of these performance characteristics combine to deliver overall postal efficiency and contribute to the successful shipment of documents."

Additionally, to combat bending and buckling often associated with envelope window films, PROCITE film contains high stiffness as gauge tolerance limits allowing for a consistently flat film. This characteristic prevents misreads, which may potentially delay the sorting process.

To benefit the growing needs of customers, Dow utilized the Six Sigma process to increase production of PROCITE envelope window film at the Hebron (Licking River), Ohio, facility by nine percent since the first quarter of 2000. The Six Sigma process is the discipline Dow is using to focus on product and service excellence by measuring, analyzing, improving and controlling the manufacturing processes to create a culture that demands perfection – on target, every time for customers.

"The success achieved in 2000 prompted us to continue incorporating Six Sigma into the production of PROCITE film," Watkins said. "We are anticipating an additional 10 percent production increase by mid-2001, without sacrificing product quality, as product reputation and customer satisfaction still remain our top priority."
