Because of the high capital cost to build an EVOH plant, and the complexity of making a food grade product, only a few companies produce EVOH:
Kuraray produces EVOH resin under the name "EVAL," with 10,000 ton plant in Okayama, Japan; a 35,000 ton plant in the U.S. (near Houston, TX) under its subsidiary Kuraray America; and a 24,000 ton plant in Belgium under its subsidiary EVAL Europe.[1]
