EVAL™ EVOH high barrier resins and films
EVAL™, the worlds leading EVOH
Imagine a plastic wall that is 10 metres thick. Not very much is going to get through a barrier like that. Now imagine that the same protective function can be realised with only 1 mm. With EVAL™ EVOH it can. Normally an EVAL™ layer of just a few microns is enough to provide an amazingly effective gas and aroma barrier, to protect the quality of packaged goods. Like food or cosmetics or vitamins. Even the fuel in a car.
EVAL™'s barrier properties give more performance per thickness than any conventional polymer, and the barrier function works in both directions.
Protecting quality and value
EVAL™ adds real function to packaging by keeping oxygen and MOSH/MOAH out and locking flavour and atmosphere in where they belong. This protects quality and value, prolongs shelf life without artificial additives and reduces waste, often while reducing the total amount of packaging. This allows for innovative plastic structure designs that are both reliable and safe in use, usually reducing environmental impact and generating savings throughout the product life cycle.
When used in barrier structures for construction, agricultural and automotive fuel system applications, EVAL™ helps create light-weight structures that help protect the environment from gas, fuel or chemical emissions.
Recyclable and recoverable
EVAL™ EVOH is recyclable, and is commonly used as part of a regrind structural layer in rigid packaging and automotive applications. It can also be used for post-consumer recycling, and will not disrupt polyolefin recycling streams. A very high proportion of energy is recoverable from EVOH, often reducing the amount of extra fuel necessary for thermal disposal of sorted waste. EVAL™ does not contain chlorine or metals that can later be released into the environment.
In 1926 Kuraray Co., Ltd. was established in Kurashiki City, Japan, where it started the industrial production of viscose rayon. Through intensive research and development the company succeeded in building up extensive expertise and technological strength in the fields of polymer chemistry, synthetic chemistry and chemical engineering. Thanks to this technological strength and extensive expertise Kuraray was able to develop highly innovative products in a wide range of selected businesses.
Today Kuraray develops and manufactures quality and innovative products ranging from synthetic resins, fine chemicals, non-woven fabrics, man-made leather to laser discs and medical products. A number of products developed and manufactured by Kuraray have become world-leading products. Among these products are: polyvinyl alcohol fiber KURALON™, polyvinyl alcohol resin POVAL™, ethylene-vinyl alcohol copolymer EVAL™, manmade leather CLARINO™ and isoprene-based fine chemicals for perfumes, pharmaceuticals, and other specialized applications.
