For fresh domestic fish transport, a more environmental friendly way of packaging fresh fish. The established expanded polystyrene eps tray packaging has been under heavy dispute for environmental reasons. Following a rigorous selection, mondi&rsquos barrier liner concept was selected as one of the alternative materials. An effective solution for the development of the afcofish tray, providing an absolute watertight and highdegree of moisture vapour barrier. Mondi´s paratén® a suitable and reliable alternative when a real barrier is needed. Using this type of liner, combined with efficient designs, shows the alternative to the eps in the nearest future. The barrier liner concept allows considerable weight reduction in liner and fluting material, cost effective use of recycled materials and is fully recyclable. The corrugated board industry is indeed facing several new challenges, mainly with regards to sustainability. These include for instance the need for packaging weight reduction and substitution from virgin fibre materials to recycled liner and fluting qualities as well as the increasing demand for highquality printing. These are just some of the most recent developments which the corrugated board industry has to cope with. A full range of technologies like extrusion coating, laminating, siliconising and printing, has developed new types of liner materials that meet these new demands.
