Abstract: A packaging laminate for a packaging container, which includes a paper or paperboard layer and outer, liquid-tight, heat-resistant layers of plastic on both sides of the paper or paperboard layer. Between the paper or paperboard layer and the outer plastic layer, the packaging laminate has at least one additional layer of a material possessing tightness properties vis-à-vis gases. In order to improve the preconditions for being able to provide the packaging laminate with decorative artwork of printing ink with good print quality, the paper or paperboard layer has, on both sides, a coating of pigment, adhesive and a substance capable of modifying the rheological properties of the coatings.

Abstract: A packaging laminate for a retortable packaging container which comprises a paper or paperboard layer and outer, liquid-tight, heat-resistant layers of plastic on both sides of the paper or paperboard layer. Between the paper or paperboard layer and the outer plastic layer, the packaging laminate has at least one additional layer of a material possessing tightness properties vis-à-vis gases. In order to improve the preconditions for providing the packaging laminate with decorative artwork of printing ink with good print quality, the paper or paperboard layer has, on its one side, a printable coating of pigment and binder or adhesive, and on its other side a coating of starch.
