Abstract

Oppfinnelsen vedrører et barrieremateriale for bruk som emballasje, særlig for næringsmidler, samt en fremgangsmåte til fremstilling av et slikt barriere- materiale med gode oksygenbarriereegenskaper. Man har funnet at ved å blande inn et fiberholdig materiale i en polyolefin dannes et transkrystallinsk sjikt av polyolefmen mot fibermaterialet. Dette transkrystallinske sjikt utgjør den direkte årsak til materialets barriereegenskaper. Man har funnet at fibermaterialet herved utgjør kim for dannelsen av et slikt sjikt, og at dette i stor grad er bestemt av fibermaterialets egenskaper og den tid en har til rådighet for krystallisasjonen.The invention relates to a barrier material for use as packaging, especially for foodstuffs, and to a method for producing such a barrier material with good oxygen barrier properties. It has been found that by blending a fibrous material into a polyolefin, a transcrystalline layer of the polyolefin is formed against the fibrous material. This transcrystalline layer is the direct cause of the barrier properties of the material. It has been found that the fibrous material thereby constitutes germ for the formation of such a layer, and that this is largely determined by the properties of the fibrous material and the time available for crystallization.
