Zusammenfassung:	A substrate (2) for foodstuff packaging material (1), wherein the substrate (2) comprises cellulose fibres and has a first major surface (2a) opposite a second major surface (2b) and a first coating layer (3) arranged on at least a portion of the first major surface (2a). The first coating layer (3) has a total dry matter weight of 4-15 g/mand comprises starch, amounting to 20-45 percent by weight of the total dry matter weight of the first coating layer, latex, amounting to 10-35 percent by weight of the total dry matter weight of the first coating layer, and pigment, amounting to 35-55 percent by weight of the total dry matter weight of the first coating layer, wherein a ratio of latex to starch is 0.25:1 to 2.5:1.
