Abstract (en)

[origin: WO2023051954A1] A layer of barrier coating to fatty substances and/or to gases having the distinctive feature of being flexible, to the point of being able to withstand creasing and folding, is proposed. It comprises a non-crosslinked fluidized starch having a weight-average molecular mass greater than or equal to 3000 kDa and a polyol chosen from sorbitol, xylitol, maltitol or glycerol. The barrier coating layer is notably of use for the manufacture of food packaging made of paper or board, intended to contain fatty food.
