A paper web includes a surface having a plurality of sections. At least one section of the plurality of sections has a plurality of positions. The plurality of positions each has an equal length and is obtained by subdividing the at least one section. The paper web also includes ink applied to the surface of the paper web at some of the plurality of positions.

A method of controlling a converting line that produces a paper product. The method includes unwinding a paper web from a parent roll on a converting line having a plurality of operational parameters. The paper web includes a plurality of sections and a plurality of marks, with at least one mark assigned to each of the plurality of sections and each mark associated with a paper rating. At least one of the plurality of marks is read with a mark reading unit. The paper rating associated with the at least one mark read by the reading unit is obtained. At least one operational parameter of the converting line based upon the obtained paper rating is changed. The paper web is converted into a paper product.

The present invention relates to a water-, oil- and grease-resistant multilayer coating for a paper-based substrate comprising a water-based inner primer coating, an intermediate polymeric extrusion coating, and a water-based top barrier coating, wherein a surface of the paper-based substrate coated therewith has water, oil and grease barrier properties, and wherein the paper-based substrate coated therewith is repulpable and recyclable.

Disclosed are energy curable primer compositions for use on uneven substrates such as paper or board to help create a non-porous, smooth, print-receptive surface for subsequent in-line or off-line application of metallic or special effect inks for generating a superior appearance such as a mirror-like metallic or other special effect for promotional or high-value packaging applications. Compositions suitable for low odor and low migration indirect contact food, tobacco, or pharmaceutical product packaging are also disclosed.

The invention relates to a process for preparing an aqueous dispersion of a polymer P, which comprises the emulsion polymerization of vinyl acetate, an acrylate monomer, which is a C.sub.1-C.sub.10 alkyl acrylate or a C.sub.1-C.sub.10 methacrylate, an ,-ethylenically unsaturated C.sub.3-C.sub.8 carboxylic acid, glycidyl methacrylate or glycidyl acrylate, optionally an ethylenically unsaturated sulfonic acid and optionally an ethylenically unsaturated other monomer. Furthermore, the aqueous polymer dispersion obtainable from this process and a powder form thereof are disclosed. They are useful for a paper coating slip containing one of the aforementioned forms. A paper or a cardboard, which is coated with the paper coating slip, shows surface strength, which is expressed by a good dry pick resistance, a good wet pick resistance or good offset test results. The aqueous polymer dispersion or the powder form thereof is furthermore useful as a binder.

The present technology provides a method for preparing an acid-reducing filter that includes depositing a mineral blend layer to a filter substrate, where the mineral blend layer comprises calcium carbonate and magnesium carbonate at a weight ratio of about 1:10 to about 10:1, the mineral blend is free of soluble halide or hydroxide salts of alkali or alkaline earth metals, and the mineral blend layer is insoluble in water.

A process of depositing a hydrophobic or superhydrophobic film on a surface of a substrate, effected by spraying onto the substrate's surface a solution comprising a fatty acid and an organic solvent, is provided. Substrates and articles-of-manufacturing containing the substrates, having a hydrophobic or superhydrophobic coating/film deposited thereon, obtainable or prepared by the process, are also provided. The process is usable for reducing a load of a pathogenic microorganism and/or for preventing biofilm formation on and/or in the substrates or articles-of-manufacturing containing same.

Method for hydrophobing a cellulose substrate (1), which comprising a first side and a second side, which faces away from the first side. The method comprising the steps of drying a cellulose substrate (1) to a dry content above 80%, preferably above 85%, adding a vaporized fatty acid halide, to the first side of the cellulose substrate, and, at the same time perform vacuum sucking at the second side of the cellulose substrate, such that, the vaporized fatty acid penetrates the cellulose substrate (1) in a predetermined direction through the substrate.

A process for manufacturing continuous ceramic tape includes steps of heating a ceramic feedstock to a molten state and spraying molten droplets of the feedstock onto a deposition surface. The method further includes forming a ceramic coating on the deposition surface by accumulating the droplets, which solidify and are directly bonded to one another. The deposition surface is non-stick with respect to the ceramic coating such that the coating may be peeled off of the deposition surface as a continuous ceramic tape, without fracture. Additionally, in embodiments, the deposition surface is removed by running the deposition over a bending edge, chemically stripping or dissolving the deposition surface, or burning the deposition surface.

The present disclosure is directed to a rotary screen printing apparatus, comprising: a rotary cylindrical screen; a conduit which provides fluid communication to an internal volume of the rotary cylindrical screen; and, a heater whose output is directed towards the conduit.
