Title (EN) SEALANT FILM AND PACKAGING MATERIAL
(FR) FILM DE SCELLEMENT ET MATÉRIAU D'EMBALLAGE
(JA) シーラントフィルム及び包装材
Abstract:
(EN) Provided is a sealant film, characterized in that: the sealant film comprises a laminated film in which an outer layer, an intermediate layer, and an inner layer are laminated; the outer layer and the inner layer contain a polyethylene-based resin; the intermediate layer contains a straight-chain low-density polyethylene and a cyclic olefin-based resin; the cyclic olefin-based resin content in the resin constituents contained in the intermediate layer is 20–40% by mass; and the standardized molecular orientation Morc value, when the reference thickness measured using a microwave molecule orientation meter is 60 µm, is at least 1.025. Through the use of the sealant film, outstanding ease of tearing and straight cutting properties can be achieved, and during high-temperature processing, inner-surface fusion of a packaging material and an uneven exterior-appearance thereof can be suppressed.
(FR) L'invention concerne un film de scellement, caractérisé en ce que : le film de scellement comprend un film stratifié dans lequel une couche externe, une couche intermédiaire et une couche interne sont stratifiées; la couche externe et la couche interne contiennent une résine à base de polyéthylène; la couche intermédiaire contient un polyéthylène basse densité à chaîne droite et une résine à base d'oléfine cyclique; la teneur en résine à base d'oléfine cyclique dans les constituants de résine contenus dans la couche intermédiaire est de 20 à 40 % en masse; et la valeur de Morc d'orientation moléculaire normalisée, lorsque l'épaisseur de référence mesurée à l'aide d'un dispositif de mesure d'orientation de molécule à micro-ondes est de 60 µm, est d'au moins 1,025. Grâce à l'utilisation du film de scellement, une facilité remarquable de déchirement et des propriétés de coupe droite peuvent être obtenues, et pendant un traitement à haute température, une fusion de surface interne d'un matériau d'emballage et un aspect extérieur irrégulier de ce dernier peuvent être supprimés.
(JA) 外層、中間層及び内層が積層された積層フィルムからなり、外層及び内層がポリエチレン系樹脂を含有し、中間層が、直鎖状低密度ポリエチレン及び環状オレフィン系樹脂を含有し、前記中間層中に含まれる樹脂成分中の前記環状オレフィン系樹脂の含有量が20~40質量%であり、マイクロ波方式分子配向計にて測定される基準厚さを60μmとしたときの規格化分子配向MORc値が1.025以上であることを特徴とするシーラントフィルムにより、優れた易引き裂き性や直進カット性を実現でき、高温処理時の包装材の内面融着や外観ムラを抑制できる。
