Description
Kuraray EVAL L171B is an EVOH resin, also known as Ethylene Vinyl Alcohol Copolymer. It is designed for applications requiring ultra-high gas barrier performance. With a low ethylene content of 27 mol%, L171B provides one of the highest oxygen barrier levels among standard EVOH grades.
EVAL L171B is suitable for high barrier packaging structures where oxygen protection, aroma retention, flavor preservation and shelf-life extension are critical. It can be used in multilayer co-extrusion structures with PE, PP, PA and other polymers to improve the barrier performance of flexible and rigid packaging.
