摘要： An intermediate laminate product includes a first paper layer including lignocellulose fibres, and a dry coating layer applied to one surface of the first paper layer, the coating including expandable microspheres having an expansion temperature (TE), at least one polysaccharide, and a plasticizing additive which is capable of forming a thermoplastic blend with the polysaccharide. An expanded laminate structure includes the intermediate laminate product and a second paper layer comprising lignocellulose fibres, which is attached to the dry coating by heat lamination. A liquid packaging board includes the expanded laminate structure and a liquid barrier layer. A process for forming the expanded laminate structure includes applying a second paper layer to the coating of the intermediate product at a second temperature (T2), which is above the expansion temperature (TE) of the microspheres, whereby the microspheres expand, and at which the plasticizing additive causes plasticizing of the polysaccharide, to form a thermoplastic blend.

摘要： A papermaking additive comprising cellulose nanofibers whose aqueous solution at a concentration of 2% (w/v) has a B-type viscosity (60 rpm, 20°C) of 500 to 7000 mPa·s, preferably 500 to 2000 mPa·s is used to prepare a paper having improved air resistance and smoothness. This additive is prepared by oxidizing a cellulosic material with an oxidizing agent in the presence of (1) N-oxyl compound(s) and (2) bromide, iodide or a mixture thereof to prepare oxidized cellulose, and finely grinding the oxidized cellulose in a wet condition to convert the oxidized cellulose into nanofibers.

The greaseproof paper includes a paper base and a greaseproof layer provided on at least one surface of the paper base, wherein the greaseproof layer includes an ethylene-vinyl alcohol-vinyl ester copolymer (A) and a fatty acid derivative (B), contains 1 to 100 parts by mass of the component (B) per 100 parts by mass of the component (A), and is in an amount of 0.5 to 5.0 g/m 2 in terms of dry mass. In the greaseproof paper, the ethylene-vinyl alcohol-vinyl ester copolymer (A) has a content of ethylene units of 1 to 15 mol%, has a total content of vinyl alcohol units and vinyl ester units of 85 to 99 mol%, and has a degree of polymerization of 300 to 2000. In the greaseproof paper, the fatty acid derivative (B) is a fatty acid amide compound.

摘要： A cellulose nanofiber (CNF) powder of the present invention contains cellulose nanofibers, and a hydrophobic polymer that is chemically bonded to at least some of the -OH groups of the cellulose nanofibers. The CNF powder has the ability to be dispersed in water and to return to a powder form again when an aqueous dispersion of the CNF powder is dried. The distance between the fibers in the CNF powder in a dry state is 3 nm or more, and preferably 8 to 12 nm. Since the distance between the fibers in the conventional cellulose nanofibers is about 1 nm, the present invention reduces the Van der Waals force between the fibers (i.e., the force of attraction between the fibers) to one millionth of that of the conventional cellulose nanofibers. Thus, the present invention provides the CNF powder that can be used in a powder form, and that can also be reversibly changed between a powder state and a dispersed state in water, and a method for producing the CNF powder.
摘要翻译：本发明的纤维素纳米纤维（CNF）粉末含有纤维素纳米纤维和与纤维素纳米纤维的至少一部分-OH基团化学结合的疏水性聚合物。当CNF粉末的水分散体干燥时，CNF粉末能够分散在水中并再次返回粉末形式。干燥状态下的CNF粉末中的纤维之间的距离为3nm以上，并且优选8至12nm。由于常规纤维素纳米纤维中纤维之间的距离为约1nm，因此本发明将纤维间的范德瓦尔斯力（即纤维之间的吸引力）降低至常规纤维素纳米纤维的百万分之一。因此，本发明提供可以以粉末形式使用并且也可以在粉末状态和水中的分散状态之间可逆地改变的CNF粉末以及生产该CNF粉末的方法。
