Kuraray has been manufacturing and marketing ethylene vinyl-alcohol copolymers (EVOH) under the name EVAL™ since 1972, and remains the world leader in EVOH production and market development.

EVAL™ helps food producers and distributors make packaging more efficient and avoids waste while conserving energy and resources, as well as reducing the total amount of packaging materials needed.  EVAL™’s barrier properties excel against the permeation of gases and give more performance per thickness than any conventional polymer. This allows the use of less product while at the same time exceeding the performance of other materials.

Because it shuts out oxygen, protecting anything wrapped in it from deterioration, it is suitable as a packaging material for a broad range of foods. Demand is also expanding in other fields such as the automotive industry in the production of plastic gasoline tanks, as it prevents leakage and contributes to the reduction of vehicle weight. In the field of construction, EVAL™ pipes are used as a substitute for metal pipes in-floor heating systems. EVAL™’s effective and efficient characteristics make it useful in many industries.
