| description | The present invention relates to a method for manufacturing a dispersion coated fiber-based substrate, said method comprising the steps of:a) forming a fibrous web from one or more fiber suspensions, at least one of said fiber suspensions being a broke suspension, and dewatering, and optionally drying, the fibrous web to obtain a fiber-based substrate having a first main surface and a second main surface;b) forming a dispersion coating layer on the first main surface by applying a dispersion coating composition comprising, in a liquid medium:50-99 wt% of dispersed PHA (polyhydroxyalkanoate) particles, based on the total solid content of the dispersion coating composition, and1 -50 wt% of dissolved low molecular weight polyol dispersant, based on the total solid content of the dispersion coating composition,wherein the dispersion coating composition has a total solid content in the range of 20-80 wt%, and drying the applied dispersion coating composition to obtain a dispersion coated fiber-based substrate;wherein the broke suspension in a) comprises 0.1-20 wt% of PHA based on the total solid content of the broke suspension. |
