Abstract: The invention relates to a coated paperboard (10) for beverage container carriers (30) comprising: a paperboard substrate (12), a dispersion coating layer (18, 20) on each side (14, 16) of the paperboard substrate (12), wherein the paperboard substrate (12) comprises wet strength agents in an amount in a range from ?0 wt % to ?0.05 wt %, based on the dry solid content of the substrate (12) and sizing agents for making the paperboard (12) substrate more hydrophobic, wherein the sizing agents are present in an amount of ?0.15 wt %, especially in a range from ?0.15 wt % to ?0.5 wt %, based on the dry solid content of the substrate (12). The invention further relates to a beverage container carrier (30) comprising or being made from the aforementioned coated paperboard (10).

Abstract: The present invention relates to process for the production of a coated substrate comprising cellulosic fibers, the process comprising the steps of: i) providing a first substrate comprising cellulosic fibers and having a dry content of less than 50%; ii) applying a coating composition to the first substrate in an amount of more than 5 g/m2, calculated as dry weight of the coating composition, wherein the coating composition comprises: microfibrillated cellulose (MFC), and optionally a water retention agent selected from carboxymethyl cellulose (CMC), anionic polyacrylamide (A-PAM), sodium polyacrylates, polyacrylic acid derivatives, guar gum, alginate, MFC prepared from carboxymethylated fibers, MFC prepared from oxidized fibers, MFC prepared by CMC-functionalized fibers, and/or combinations thereof; and iii) mechanically dewatering the first substrate. The present process provides an energy efficient coating process which can be performed online.
