    Abstract: The present invention relates to single face or double faced corrugated fiberboard comprising one or more corrugated plies, wherein at least one of the linerboard plies or corrugated plies is a paper-film assembly comprising:i) a 30 to 600 g/m2 grammage papery material of construction, ii) a biodegradable polymeric coating from 1 to 100 μm in thickness. More particularly, the present invention relates to single face or double faced and/or corrugated fiberboard comprising one or more corrugated plies, wherein at least one of the linerboard plies or corrugated plies is a paper-film assembly comprising:i) a 30 to 600 g/m2 grammage papery material of construction as outer layer, ii) a biodegradable polymeric coating from 1 to 100 μm in thickness as interlayer, and iii) a 30 to 600 g/m2 grammage papery material of construction as inner layer. The present invention further relates to methods of producing this corrugated fiberboard.
