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

30 June 2019

Vast quantities of food are thrown away every year. Modern plastic packaging keeps food fresh and preserves its flavor for longer, so it reduces the amount of valuable produce that is wasted. 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.

Packaging keeps food fresh and safe for longer. Specialty chemicals company Kuraray markets high-performance polymers for packaging applications. Its water-soluble ethylene vinyl alcohol copolymer Exceval, its barrier copolymer Eval, and its biopolymer Plantic preserve flavor and protect food from atmospheric oxygen and pollutants. The properties of these barrier materials help reduce food waste. At the same time, they make a contribution to cutting packaging waste and meeting the European Union's targets for sustainable packaging.

Protection against Oxidation

Barrier plastics protect food from gases such as atmospheric oxygen, so it stays fresh for longer. They can be used in various types of packaging and packaging processes, from coating of films to retort packaging.
The barrier copolymer Eval is one of these materials. This polymer is suitable for use in co-extrusion processes and co-injection processes and as a monolayer for lamination. Eval keeps out oxygen so food retains its flavor. A layer as little as four micrometers of this polymer also protects packaged food from impurities such as mineral oils from recycled cartons.
