摘要:
The invention relates to a packaging board comprising a fibrous base and one or more polymer coating layers on one or both sides of the fibrous base. According to the invention the fibrous base contains the combination of an alkyl ketene dimer size, stearic acid anhydride, a wet-strength size and an aluminium com- pound, which give the board resistance to aggressive liquids as well as thermal treatment, particularly an improved resistance to raw edge penetration in such circumstances. The invention further relates to containers and packages made of the board, for instance disposable drinking cups, dairy product cartons and auto- clave packages, as well as use of the board for such purposes.
摘要:
Process for treating a fibrous material, to make said material hydrophobic and/or water-repellent, comprising the operation of impregnating said material with a suspension comprising nanoparticles of a hydrophobic material and a cyanoacrylate in an organic solvent and causing the crosslinking of said cyanoacrylate; the process uses an amount of cyanoacrylate and a weight ratio with the nanoparticles such as to produce complete or partial coating of the fibrous material with a matrix of crossliiiked cyanoacrylate in which said nanoparticles are dispersed.
摘要:
An article in the form of recyclable packaging material having a water vapor transportation rate of about 500 g/m2/day or less. The packaging material has a paper substrate of recyclable paper fibers and a print-receptive layer which is positioned over the outer surface of the paper substrate and has a Parker Print Smoothness value of about 1.5 or less. The packaging material also has a moisture barrier layer positioned over the print- receptive layer. The moisture barrier layer is formed from one or more energy-cured polymers. Also, methods for preparing these packaging materials, including printed packaging materials.

摘要:
A method for rendering a substrate hydrophobic includes treating the substrate with an acyloxysilane. The treatment includes impregnating the substrate with an acyloxysilane and thereafter curing (hydrolyzing and condensing the acyloxysilane) to form a silicone resin. The method is particularly useful for rendering paper hydrophobic.
摘要:
The invention relates to a process for the preparation of surface sizing composition comprising separately adding to an aqueous component comprising at least 80 wt% of water: (a) an aqueous dispersion comprising an alkenylsuccinic anhydride (ASA); and, (b) a non-ionic, amphoteric, cationic, or anionic polymer. The invention also relates to a composition obtainable thereby and a process for surface treatment of paper.
摘要:
The present invention relates on the use of 1,3-dihydroxyalkyl functionalized polyorganosiloxanes in compositions for the treatment of materials having a fibrous structure, such as leather, furs, textiles and paper. The invention further relates to a process for treating fibrous materials with waterproofing.
摘要:
The invention describes a pigment coated paperboard adapted for sterilizable packages and comprising one or more layers, with a pigment coated top layer of bleached kraft pulp. The paperboard has a density in the range of 700 to 870 kg/m 3 and is hydrophobic from a sizing agent treatment of each layer, wherein the pigment coating comprises a pigment, a binder, and a rheology modifier, and wherein the pigment comprises at least 50 weight% calcium carbonate, the binder comprises an acrylic co-polymer, and the rheology modifier comprises an acrylic co-polymer. According to the invention is also defined a corresponding method and use of the paperboard for producing a package, as well as a package.
