Abstract
(EN)
Provided is a layered body having two or more polyolefin resin layers, wherein: at least one polyolefin resin layer (A) is formed by dispersing cellulose fibers including cellulose fibers having a fiber length of 0.3 mm or more; the content of the cellulose fibers in the polyolefin resin layer (A) is 1% by mass or more and less than 60% by mass; and a polyolefin resin layer (B) different from the polyolefin resin layer (A) is layered in contact with the polyolefin resin layer (A).
(FR)
L'invention concerne un corps stratifié ayant deux couches de résine de polyoléfine ou plus, dans lequel : au moins une couche de résine de polyoléfine (A) est formée par dispersion de fibres de cellulose comprenant des fibres de cellulose ayant une longueur de fibre supérieure ou égale à 0,3 mm ; la teneur des fibres de cellulose dans la couche de résine de polyoléfine (A) est supérieure ou égale à 1 % en masse et inférieure à 60 % en masse ; et une couche de résine de polyoléfine (B) différente de la couche de résine de polyoléfine (A) est stratifiée en contact avec la couche de résine de polyoléfine (A).
(JA)
2層以上のポリオレフィン樹脂層を有する積層体であって、 少なくとも1層のポリオレフィン樹脂層(A)が、繊維長0.3mm以上のセルロース繊維を含むセルロース繊維を分散してなり、該ポリオレフィン樹脂層(A)中のセルロース繊維の含有量が1質量%以上60質量%未満であり 前記ポリオレフィン樹脂層(A)に接して前記ポリオレフィン樹脂層(A)とは異なるポリオレフィン樹脂層(B)が積層された積層体。
