Abstract:
(EN) Provided are: an easily-torn film that has excellent straight-line cutability, high oxygen barrier properties, and a low modulus of elasticity; a multilayer film; a packaging material; and a container. An easily-torn film that includes a polyamide resin component that comprises: more than 20 parts by mass but no more than 70 parts by mass of a semi-aromatic polyamide resin A; and at least 30 parts by mass but less than 80 parts by mass of an aliphatic polyamide resin B. The semi-aromatic polyamide resin A is configured from diamine-derived structural units and dicarboxylic-acid-derived structural units. At least 60 mol% of the diamine-derived structural units are derived from meta xylene diamine, and at least 60 mol% of the dicarboxylic-acid-derived structural units are derived from C4–10 α,ω-straight-chain aliphatic dicarboxylic acids. The molar concentration of phosphorous atoms, the total molar concentration of alkali metal atoms, and the total molar concentration of alkali earth metal atoms in the semi-aromatic polyamide resin satisfy a prescribed relationship with Mn.
(FR) L'invention concerne : un film facilement déchiré qui a une excellente aptitude au découpage en ligne droite, des propriétés de barrière à l'oxygène élevées, et un faible module d'élasticité ; un film multicouche ; un matériau d'emballage ; et un récipient. Un film facilement déchiré selon l'invention comprend un composant de résine polyamide qui comprend : plus de 20 parties en masse mais pas plus de 70 parties en masse d'une résine polyamide semi-aromatique A ; et au moins 30 parties en masse mais moins de 80 parties en masse d'une résine polyamide aliphatique B. La résine polyamide semi-aromatique A est configurée à partir de motifs structuraux dérivés de diamine et de motifs structuraux dérivés d'acide dicarboxylique. Au moins 60 % en moles des motifs structuraux dérivés de diamine sont dérivés de méta-xylène diamine, et au moins 60 % en moles des motifs structuraux dérivés d'acide dicarboxylique sont dérivés d'acides dicarboxyliques aliphatiques à chaîne α,ω-linéaire C4–10. La concentration molaire d'atomes de phosphore, la concentration molaire totale d'atomes de métal alcalin et la concentration molaire totale d'atomes de métal alcalino-terreux dans la résine polyamide semi-aromatique satisfont à une relation prescrite avec Mn.
(JA) 直線カット性に優れ、酸素バリア性が高く、弾性率の低い易裂性フィルム、ならびに、多層フィルム、包装材料および容器の提供。20質量部を超え70質量部以下の半芳香族ポリアミド樹脂Aと、80質量部未満30質量部以上の脂肪族ポリアミド樹脂Bとからなるポリアミド樹脂成分を含み、半芳香族ポリアミド樹脂Aがジアミン由来の構成単位とジカルボン酸由来の構成単位とから構成され、ジアミン由来の構成単位の60モル%以上がメタキシリレンジアミンに由来し、ジカルボン酸由来の構成単位の60モル%以上が炭素数4~10のα,ω-直鎖脂肪族ジカルボン酸に由来し、半芳香族ポリアミド樹脂のリン原子のモル濃度、アルカリ金属原子の合計モル濃度およびアルカリ土類金属原子の合計モル濃度およびMnが所定の関係を満たす易裂性フィルム。
