Abstract:
The present invention relates to paper or paperboard comprising cellulose fibers, said paper or paperboard comprising at least one coating layer formed by extrusion coating of a PP (polypropylene) resin, characterized in that the PP resin comprises at least 50 % by weight of a branched PP copolymer having a density in the range of 890-910 kg/m3 (as determined according to ISO 1183), a melting temperature in the range of 155-170 °C (as determined according to ISO 11357- 3), and a melt flow rate (230 °C / 2.16 kg) in the range of 10-15 g/10 min (as determined according to ISO 1133), and wherein the PP resin is applied to the paper or paperboard at a grammage of less than 30 g/m2.
Abstract:
The invention relates to a barrier coating composition comprising 30 – 70 weight- % of styrene (meth)acrylate copolymer, which is polymerised in the presence of a stabiliser, and which has a glass transition temperature Tg ≤ 20 °C, preferably ≤ 10 °C, 30 – 70 weight-% of polyvinyl alcohol, and at the most 5.0 weight-% of a cross-linker, which reacts with –OH or –COOH groups. The invention relates also to a sheet-like product coated with the said coating composition.
Abstract:
The invention relates to a disposable container of fibrous board comprising a bottom (3) and an upward mantle (2) heat-sealed thereto. The material for both the bottom and the mantle is a polymer coated fibrous board, in which the coating covers at least the inner surfaces of the container. According to the invention the material comprises a fibrous board base (8) such as paperboard or cardboard, an extruded inner coating layer (9) of a blend of polyethylene (PE) and polypropylene (PP), and an extruded outer coating layer (10) of polypropylene-olefin copolymer (PP-c). The inner coating layer (9) secures adhesion with the board base (8) and the outer coating layer (10) is for liquid-proof heat-sealing between the bottom (3) and the mantle (2) of the container. The container is in particular a microwave ovenable cup or food tray.
Abstract:
L'invention concerne le domaine de la fabrication du papier et concerne plus particulièrement une méthode de fabrication d'un papier imprégné d'une molécule d'intérêt, en particulier un papier coloré ainsi que le produit associé c'est-à-dire un papier imprégné, ledit procédé mettant en œuvre un fluide à pression supercritique. Un tel papier, en particulier coloré, obtenu à partir d'une formulation de pâte à papier ou de papier comprenant du latex, ne dégorge pas au contact de l'eau.
Abstract:
The present invention provides a core/shell polymer particle for surface sizing of cellulosic products, wherein the core polymer and the shell polymer of the core/shell polymer par- ticle are polymerized from monomers comprising at least 40%, by weight of monomers selected from branched C3-10- alkyl (meth)acrylate, styrene, linear C1-10-alkyl (meth)acry- late, and acrylonitrile, based on the total weight of the mon- omers of the core/shell polymer particle; provided that the polymer of the core/shell polymer particle comprises at least 40% by weight of branched C3-6-alkyl (meth)acrylate and at least 50% by combined weight of branched C3-10- alkyl (meth)acrylate and styrene, linear C1-10-alkyl (meth)acrylate, and/or acrylonitrile, based on the total weight of the monomers of the core/shell polymer particle.
Abstract:
This invention relates to a water based composition for coating paper, particularly paper based food and confectionary packaging and to a method of manufacturing the composition. The invention includes paper products coated with the composition, particularly paper food and confectionary packaging adapted to replace hot wax coated packaging. The composition comprises 10 to 30% by volume of an aqueous film forming heat-seal acrylic emulsion and 15 to 40% by volume of an aqueous ethylene acrylic copolymer resin in a blend vehicle constituted by an aqueous polyethylene emulsion together with one or more additives, in which the acrylic emulsion is a styrene acrylic resin and in which the additives include one or more of an emulsion stabiliser, an anti-foaming agent and a lubricant that is formulated to provide slip and anti-blocking characteristics.
Abstract:
Sheet-like products, such as tissue products, are disclosed containing an additive composition. The additive composition, for instance, comprises an aqueous dispersion containing an alpha-olefin polymer, an ethylene-carboxylic acid copolymer, or mixtures thereof. The alpha-olefin polymer may comprise an interpolymer of ethylene and octene, while the ethylene-carboxylic acid copolymer may comprise ethylene-acrylic acid copolymer. The additive composition may also contain a dispersing agent, such as a fatty acid. The additive composition may be incorporated into the tissue web by being combined with the fibers that are used to form the web. Alternatively, the additive composition may be topically applied to the web after the web has been formed. For instance, in one embodiment, the additive composition may be applied to the web as a creping adhesive during a creping operation. The additive composition may improve the strength of the tissue web and/or improve the perceived softness of the web.
