A coating for paperboard includes polyethylene outer layers and a polyethylene inner layer with calcium carbonate filler. In addition to the lower cost, benefits include a surprising better heat sealing behavior compared with a coating of polyethylene alone.

A decorative material having first and second gloss-adjusting layers, one with lower gloss contains a matting agent having an average particle diameter of 6.0 m or more and 15.0 m or less. That is, the average particle diameter of the matting agent in the gloss-adjusting layer with lower gloss, i.e., the gloss-adjusting layer whose scratch resistance is likely to be low, is set within an optimal range in which the gloss-adjusting layer has improved or even excellent scratch resistance and designability.

A method of manufacturing a laminate comprises providing a binder impregnated core layer by impregnating at least one fibrous layer with an aqueous core binder solution having a viscocity in the range 75 cP to 500 cP at a temperature of 20 C. and a bake-out solid content in the range 40 wt % to 85 wt %, in which the aqueous core binder solution comprises (i) at least 25% by dry weight of a) reducing sugar reactant(s) and nitrogen-containing reactant(s) and/or b) curable reaction product(s) of reducing sugar reactant(s) and nitrogen-containing reactant(s); and (ii) between 5% and 15% by weight of a non-aqueous solvent based on the total weight of the aqueous binder solution; providing a semi-finished assembly by assembling the binder impregnated core layer with a surface layer; and applying heat and pressure to the semi-finished assembly to cure the binder in the binder impregnated core layer and secure the core layer and the surface layer together.

The invention provides a method for the production of a composite comprising microfibrillated cellulose (MFC) and precipitated calcium carbonate. The method is characterized in that MFC is added to a suspension of calcium hydroxide during carbonation, whereby calcium carbonate is precipitated onto fibers or fibrils of the MFC in a controlled manner. By adding microfibrillated cellulose to the calcium suspension during the carbonation, the brightness and the strength of the MFC/PCC-composite is enhanced. Moreover, the inventive method facilitates the distribution of calcium dioxide and MFC in the suspension and thus gives rise to a more homogenous product.

A coating for paperboard includes polylactic acid and an inorganic material. The inorganic material may be talc. The presence of the talc has a beneficial effect on extrusion processing behavior including lower melt temperature, lower head pressure, and lower motor load. Additionally, the presence of talc reduces edge weave and neck-in during extrusion coating processes.
