Title (EN) LAMINATED BODY AND PACKAGING IN WHICH SAME IS USED
(FR) CORPS STRATIFIÉ ET EMBALLAGE DANS LEQUEL IL EST UTILISÉ
(JA) 積層体及びこれを用いた包装材
Abstract:
(EN)  The invention provides a laminated body made of a multilayered film and a paper substrate, as well as a packaging in which the laminated body is used. The packaging adheres fast to paper and is convenient to cut manually in regard to being easily torn open without the need for any special processing; wherein the packaging undergoes minimal humidity-induced change in physical properties, resists curling, exhibits exceptional dimensional stability, and offers excellent adaptability to lamination, printing, and packaging machines. Specifically, the invention provides a laminated body characterized in being obtained by heat-fusing a resin layer (A1) of a multilayered film (I) and a paper base material (II), the multilayer film (I) having a multilayer configuration obtained by laminating the resin layer (A1) and a resin layer (B1) in the sequence (A1)/(B1)/(A2); the resin layer (A1) principally comprising an annular olefinic resin having a Tg of 130°C or greater, and the resin layer (B1) principally comprising an olefinic resin but not having an annular structure.
(FR)  L'invention concerne un corps stratifié constitué d'un film multicouche et d'un substrat en papier, ainsi qu'un emballage dans lequel est utilisé le corps stratifié. L'emballage adhère rapidement au papier et est commode à couper manuellement en ce sens qu'il est facilement ouvert par déchirement sans devoir recourir à un quelconque traitement spécial ; étant entendu que l'emballage subit un changement minimal induit par l'humidité de ses propriétés physiques, résiste à l'ondulation, présente une exceptionnelle stabilité dimensionnelle, et offre une excellente adaptabilité aux machines de stratification, d'impression et d'emballage. Spécifiquement, l'invention concerne un corps stratifié caractérisé en ce qu'il est obtenu par fusion thermique d'une couche de résine (A1) d'un film multicouche (I) et d'un matériau de base en papier (II), le film multicouche (I) possédant une configuration multicouche obtenue par stratification de la couche de résine (A1) et d'une couche de résine (B1) dans la séquence (A1)/(B1)/(A2) ; la couche de résine (A1) comprenant principalement une résine oléfinique annulaire possédant une Tg de 130 °C ou plus, et la couche de résine (B1) comprenant principalement une résine oléfinique, mais ne possédant pas de structure annulaire.
(JA)  紙との接着性が良好で、特殊加工を必要とせずに手で引き裂いて簡単に開けられる手切れ性の良い包装材であって、湿度による物性変化が小さく、カールの発生もなく、寸法安定性に優れ、ラミネート加工や印刷加工、包装機械適性が良好な包装材料として好適に用いることができる、多層フィルムと紙基材との積層体、及びこれを用いる包装材を提供する。具体的にはTgが130℃以上の環状オレフィン系樹脂を主成分とする樹脂層(A1)、環状構造を含まないオレフィン系樹脂を主成分とする樹脂層(B1)、環状オレフィン系樹脂を主成分とする樹脂層(A2)が、(A1)/(B1)/(A2)の順に積層してなる多層構成を有する多層フィルム(I)の樹脂層(A1)と、紙基材(II)とを熱融着してなることを特徴とする積層体を提供する。
