EVAL Europe - EVOH Barrier Resins

EVAL™ EVOH barrier resins add real function to packaging, reducing environmental impact and generating savings throughout product lifecycles. EVAL resins are recyclable, easy to use, and allow for innovative packaging design that is both reliable and safe.

EVAL resins’ outstanding barrier properties keep oxygen and odours out of packaging, and atmosphere and flavour inside where they belong. This protects quality and value, prolongs shelf-life without the need for artificial additives, and reduces waste.

Lightweight packaging barrier layers

EVAL EVOH can help food producers and distributors achieve packaging reduction goals. 1mm of EVAL has the same oxygen barrier properties as a 10m-thick wall of LDPE. With such outstanding performance, the common thickness of a functional EVAL barrier layer is measured only in microns, making possible a lighter weight, recyclable and all-plastic alternative to metal and glass.

Environmentally friendly barrier plastic bottles, trays and jars

As shown in several recently published LCAs, EVAL can reduce environmental impact throughout a product lifecycle. EVAL does not contain chlorine or metal, and can be recycled on stream in a structural regrind layer, or as post-consumer waste with polyolefines or PET.

Replacing glass or metal with barrier plastic bottles, trays or jars can generate both savings and reduced environmental impact in extraction, processing, transport and recovery. Only very small amounts of EVAL are necessary to provide functional barrier properties.

ISO-certified EVOH barrier resins

EVAL is widely used as a functional barrier in medical, pharmaceutical, cosmetic, agricultural and industrial packaging, and for environmental protection in plastic fuel systems and construction materials. EVAL’s barrier properties meet strict environmental emission standards for plastic fuel systems, and is the only EVOH with ISO TS16949 qualification.

EVAL is often part of a multilayer plastic structure, including very thin lamination films that can add functional barrier properties to paper, carton board, PLAs and other renewable / compostable raw materials.

Barrier films for lamination

In addition to EVAL EVOH, new KURARISTER™ barrier films for lamination offer a reliable and transparent alternative to aluminium foils. Target applications include microwaveable stand-up pouches and retortable high-barrier lidding film.
