Building better barriers

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. Value, quality, flavour and CO2 are locked inside. Oxygen, odours and contamination like MOSH/MOAH are kept outside where they belong.

Kuraray is the world's first and largest producer of EVOH plastic raw materials, sold as granules for coextrusion and coinjection, or as monolayer films for lamination.

Longer Shelf-Life, Less Waste. Barrier Materials Protect Food and Make Packaging more Sustainable

At the same time, politicians are calling for more environmentally friendly packaging. Kuraray provides key barrier materials for this, including biodegradable polymers that are impermeable to gas.read more »
