Abstract

A starch-based coating compound for packaging materials, in particular for paper, pasteboard or cardboard, wherein the starch has a molecular weight in the range of 800,000 to 50,000,000 g/mol, preferably in the range of 800,000 to 20,000,000 g/mol. The coating compound is used for surface-sealing packaging materials, to prevent the passage of mineral oil contaminants from the packaging material into packaged goods. The subject disclosure furthermore relates to a multi-layer packaging material, which is produced using the coating compound, and to a method for producing said packaging material.
