Title (EN) PACKAGING FILM AND MULTILAYERED FILM FOR PACKAGING
(FR) FILM D'EMBALLAGE ET FILM MULTICOUCHE POUR EMBALLAGE
(JA) 包装用フィルムおよび包装用積層フィルム
Abstract:
(EN) [Problem] To provide a packaging film which is extremely low in absorption/adsorption property and has excellent toughness, and which is suitable for packaging products that contain a volatile medicinal ingredient or a fragrant ingredient. [Solution] A packaging film consisting substantially of a cycloolefin resin and having been biaxially oriented. Preferably, the cycloolefin resin has a glass transition temperature of 60-120ºC. Preferably, the packaging film has a thickness of 5-30 µm. Preferably, the biaxial orientation has been attained by biaxial stretching, and the stretch ratios in the machine direction (MD) and transverse direction (TD) are 1.2-3.0 each.
(FR) Le problème à résoudre par la présente invention consiste à fournir un film d'emballage qui présente des propriétés d'absorption/adsorption extrêmement faibles, qui a une excellente robustesse et qui est adapté à emballer des produits contenant un ingrédient médicinal volatil ou un ingrédient parfumé. La solution selon l'invention concerne un film d'emballage sensiblement constitué d'une résine de cyclo-oléfine et ayant été orienté biaxialement. De préférence, la résine de cyclo-oléfine possède une température de transition vitreuse de 60 °C à 120 °C. De préférence, le film d'emballage a une épaisseur de 5 µm à 30 µm. De préférence, l'orientation biaxiale a été obtenue par étirage biaxial et les rapports d'étirage dans le sens machine (MD) et la direction transversale (TD) sont de 1,2 à 3,0 chacun.
(JA) [要約] [課題]揮発性の薬効成分や香り成分を含む製品の包装に適した、低収着性および靱性に優れる包装用フィルムを提供する。 [解決手段]実質的に環状オレフィン樹脂からなり、二軸配向された、包装用フィルムである。好ましくは、前記環状オレフィン樹脂は、ガラス転移温度が60℃以上、120℃以下である。好ましくは、前記包装用フィルムの厚さが5μm以上、30μm以下である。好ましくは、前記二軸配向が二軸延伸によって実現され、延伸倍率が縦方向(MD)および横方向(TD)のいずれにおいても1.2倍以上、3.0倍以下である。
