摘要： Methods of preparing partially dried or essentially completely dried compositions comprising microfibrillated cellulose and an inorganic particulate material may include microfibrillating a fibrous substrate comprising cellulose in an aqueous environment by grinding in the presence of an inorganic particulate material to form an aqueous composition comprising microfibrillated cellulose and inorganic particulate material, wherein the fibrous substrate comprising cellulose has a Canadian Standard freeness equal to or less than 450 cm, wherein the fibrous substrate to the inorganic particulate material are in a ratio of about 99.5:0.5 to about 0.5:99.5, and wherein the microfibrillated cellulose has a fibre steepness of from about 20 to about 50; by treating the aqueous composition comprising microfibrillated cellulose and inorganic particulate material to remove at least a portion or substantially all of the water of the aqueous composition to form a partially dried or essentially completely dried composition comprising microfibrillated cellulose and inorganic particulate material.

摘要： The present invention includes a label, a label sheet and a method for manufacturing the label. The label includes a paper facestock having first and second surfaces and a layer of pressure sensitive adhesive proximal to the second surface. The label can be adhered to a substrate having pre-applied indicia to cover the indicia and the label is opaque enough to prevent the viewing of the covered indicia while matching the color of the substrate.

摘要： The present invention addresses the problem of providing a composite paper which exhibits excellent oil resistance, water vapor permeability, and water resistance even when hot and oily food is wrapped therein. The above problem can be solved by using a composite paper comprising an oil-resistant layer formed on at least one surface of a base paper, wherein the oil-resistant layer comprises a vinyl alcohol polymer (A) having a content of ethylene units of 2 to 10 mol %, a viscosity-average degree of polymerization of 300 to 2000, a saponification degree of 95 to 99.5 mol %, a total content of carboxyl groups and lactone rings of 0.02 to 3 mol %, a melting point of 180 to 230° C., a content of 1,2-glycol bonds of 1.2 to 2 mol %, and a molar fraction of central hydroxyl groups in chains of three consecutive hydroxyls by a triad expression relative to vinyl alcohol units of 65 to 98 mol %, the base paper has an air permeability resistance of 1000 seconds or less and a bulk density of 0.5 to 1.0 g/cm3, and the oil-resistant layer is formed in an amount of 0.1 to 10.0 g/m2 in terms of dry mass. The oil-resistant layer may also contain a fluorine compound (B), a layered inorganic compound (C) having an average aspect ratio of 20 to 1000, a fatty acid sizing agent (D), or a cross-linking agent (E).
