Protecting so much more than your product � Building better barriers 3
Kuraray and EVAL™ As the impact we create on our environment becomes an ever greater concern, the world continues to look for solutions that are truly sustainable. At Kuraray Co., Ltd. we’re committed to contribute to an improved natural environment and quality of life. We’re involved with our local communities. We monitor and work hard to reduce the resources we use, and carefully control and target reduced emissions.
EVAL™’s barrier properties give more performance per thickness than any conventional polymer, and the barrier function works in both directions. Building better barriers
� Freshness, aroma and modified atmosphere are locked inside where you want them. � Oxygen, odours and contamination are kept outside where they belong.

We’re proud of these achievements, but what really sets us apart is our pioneering and often unique technologies, bringing value to our customers and to the world. This is the story of just one of them, EVAL™ EVOH. And this is how it works:
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. In fact, it normally takes just a few microns of this EVOH copolymer to create an amazingly effective gas and aroma barrier. In which applications does it add function and what does it mean for the environment? The answer is simple: take any valuable material that needs a protective gas or aroma barrier around it. Like food or cosmetics or vitamins. Even the fuel in your car. A very thin layer of EVAL™ is enough to do the job.
