Abstract: The present disclosure provides a coated paper product for use in a flow wrapping process, wherein: —said coated paper product comprises a paper substrate; —said paper substrate is a machine-glazed (MG) kraft paper having a glazed side and a non-glazed side; —said non-glazed side is coated with a precoating layer and a barrier coating layer; —said precoating layer comprises a polymeric binder and a pigment; and —the contact angle measured according to TAPPI T 558 between water and a surface formed by the barrier coating layer is less than 90° at the 1.0 s checkpoint.

Abstract: The present disclosure provides a coated paper product comprising: —a paper or paperboard substrate: —a barrier coating, wherein the barrier coating comprises graphene and a polyolefin copolymer bearing carboxylic acid moieties, wherein the polyolefin copolymer bearing carboxylic acid moieties preferably is ethylene-acrylic acid copolymer (EAA) or ethylene-methacrylic-acid-copolymer (EMAA) or maleic acid ethylene copolymer (MAE), and wherein the graphene content in the barrier coating is 0.3-3 wt %. There is also provided a coated paper product comprising high surface area graphite flakes having an average particle size of 2-7 ?m instead of the graphene.

Abstract: The present disclosure provides a coated paper product comprising:—a paper substrate comprising a first and second side:—a first coating layer on the first side of the paper substrate, wherein the first coating layer comprises ethylene-acrylic acid (EAA) or vinyl acetate acrylate copolymer (VAcA) or styrene-acrylate (SA) or acrylic latex; and—a second coating layer on the first coating layer, wherein the second coating layer comprises EAA and talc, and wherein the dry weight ratio of EAA to tale in the second coating layer is between 100:5 and 100:70,—wherein the coat weight of the first coating layer is at least 4 g/m2, and—wherein the coat weight of the second coating layer is at least 3 g/m2.
