ABSTRACT:
The invention relates to polymeric laminates for packaging. According to the invention, such laminates contain an oxygen barrier layer which is composed of a hydrolysed olefin/vinyl ester copolymer, preferably a hydrolysed ethylene/vinyl acetate copolymer. Other layers in the laminate protect the oxygen barrier layer from moisture and provide a heat-sealable surface layer. The laminates withstand the temperatures of 80.degree.-130.degree.C employed in pasteurisation and sterilisation procedures, and are therefore of value in the preparation of pasteurised and sterilised packages of oxygen-sensitive foodstuffs.
