Alternative PFAS-free Kuraray Poval™ and Exceval™ Kuraray Poval™ transform paper into art. With outstanding adhesion with cellulose due to hydrogen bonding, film strength, barrier properties, binding strength of filler, and dispersing performance, Kuraray Poval™ are used in a variety of paper applications. For example, the specialty grade Exceval™ enhances and improves paper performance by improving water, chemical, and oil resistance. Kuraray Poval™ offer significant advantages for strength and barrier properties in the commodity and specialty paper market. Exceval™ combines the unique properties of polymer technology with expertise in barrier technology. Using Kuraray’s expertise in EVAL™, high gas barrier plastic packaging can be extended to paper structures by either laminating or melt-curtain coating Exceval™ onto the paper substrate.
