Title (EN) BARRIER PAPER AND PAPER CUP
(FR) PAPIER PROTECTEUR ET GOBELET EN CARTON
(JA) バリア紙、紙カップ
Abstract: front page image
(EN)A barrier paper has a paper base material and a cellulose fiber-containing barrier layer formed on the paper base material. For the cellulose fiber, the integrated value from 10.0 µm to 500.0 µm obtained from a volume-based grain size distribution diagram when a dispersion containing said cellulose fiber is measured by laser diffraction is at least 30%.
(FR)Un papier protecteur selon l'invention comprend un matériau de base en papier et une couche protectrice, contenant des fibres de cellulose, formée sur le matériau de base en papier. Pour les fibres de cellulose, la valeur intégrée de 10,0 µm à 500,0 µm, obtenue d’après un diagramme de distribution de tailles de grain basées sur le volume lorsqu’une dispersion contenant lesdites fibres de cellulose est mesurée par diffraction laser, est d’au moins 30 %.
(JA)バリア紙は、紙基材と、前記紙基材上に形成されたセルロース繊維を含むバリア層と、を有し、前記セルロース繊維が、そのセルロース繊維を含有する分散液をレーザー回折法にて測定したときの体積基準の粒度分布図から得られる、10.0μm以上500.0μm以下の積算値が30%以上である。
