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).
