(57) Abstract:
(EN): The present invention pertains to a coating paper that is for tableware, and that is provided with a pair of superficial layers and a plurality of intermediate layers disposed between the pair of superficial layers, wherein: the superficial layers and the intermediate layers contain, as main components, bleached softwood kraft pulp and bleached hardwood kraft pulp; the mass ratio of the bleached softwood kraft pulp to the bleached hardwood kraft pulp in the superficial layers is 5/95 to 15/85, while the mass ratio of the bleached softwood kraft pulp to the bleached hardwood kraft pulp in the intermediate layers is 30/70 to 40/60; and the respective superficial layers have, at the surface thereof, a surface coating layer that contains a totally saponified polyvinyl alcohol. The amount at which the surface coating layer is coated is preferably 1-5 g/m2. The proportion of the sum of basis weight of the pair of superficial layers with respect to the total basis weight is preferably 25.0-35.0%.
(FR): La présente invention concerne un papier de revêtement qui est destiné à la vaisselle, et qui est pourvu d'une paire de couches superficielles et d'une pluralité de couches intermédiaires disposées entre la paire de couches superficielles, les couches superficielles et les couches intermédiaires contenant, en tant que composants principaux, de la pâte kraft blanchie de résineux et de la pâte kraft blanchie de feuillus; le rapport en masse de la pâte kraft blanchie de résineux à la pâte kraft blanchie de feuillus dans les couches superficielles est de 5/95 à 15/85, tandis que le rapport en masse de la pâte kraft blanchie de résineux à la pâte kraft blanchie de feuillus dans les couches intermédiaires est de 30/70 à 40/60; et les couches superficielles respectives ont, à leur surface, une couche de revêtement de surface qui contient un alcool polyvinylique totalement saponifié.
