Abstract:
The present invention relates to a laminated cellulose-based liquid or semi-liquid food packaging material, comprising a brown or dark bulk layer from non-bleached, cellulose-based material, an outside substrate layer having a white print surface to hide the dark colour of the bulk layer, and on the inside an oxygen barrier layer and an innermost heat sealable layer. The invention further relates to the method for manufacturing the laminated packaging material and to a packaging container for liquid food packaging, comprising the laminated packaging material.
