Abstract (en)
[origin: WO2015040134A1] The invention relates to a starch-based coating composition for packaging materials, in particular for paper, paperboard 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 invention also relates to the use of the coating composition for surface-sealing of packaging materials so that the passage of mineral oil contaminants from the packaging material into the packaged material may be prevented. The invention further relates to a multi-layered packaging material produced by using the coating composition and to a method for producing the same.
