摘要：
The present invention relates to a method for manufacturing of a laminated cellulose-based liquid or semi-liquid food packaging material, wherein the laminated packaging material has a bulk material layer comprising a low-density cellulose spacer layer, an outside module comprising a substrate layer having a print surface and an inside material module comprising a barrier layer or barrier coating. The invention further relates the laminated packaging materials obtained by the method and to a packaging container for liquid food packaging, comprising the laminated packaging material or being made from the laminated packaging material obtained by the method.
