Abstract
A packing laminate for the manufacture of packing containers for liquid contents, including an inner layer (5) of fibrous material with outer layers (6) and (7) of liquid-tight material and a color layer (8) with the object of creating a decoration or similar identification marking on the finished container. The color layer (8) is hardened through electron irradiation and in order to protect the inner layer (5) from the effect of this irradiation the laminate comprises a layer (14) applied between the inner layer (5) and the color carrying plastic layer of a material capable of absorbing electrons during the irradiation.
