Title (EN) LAMINATE FILM FOR PACKAGING MATERIALS, AND PACKAGING BAG
(FR) FILM STRATIFIÉ POUR MATÉRIAUX D'EMBALLAGE, ET SAC D'EMBALLAGE
(JA) 包装材用積層フィルム、及び包装袋
Abstract:
(EN) Provided are: a laminate film for packaging materials, which can contribute to the saving of petroleum resources and the reduction in amount of emission of carbon dioxide and is therefore environmentally friendly; and a packaging bag, in which the laminate film is used, and which has processing suitability and physical properties, particularly durability, that compare advantageously with packaging bags made from petroleum-based resins. A laminate film 12 for packaging materials, which is produced by laminating a sealant film 13 on a base film 14, wherein the sealant film 13 is made from a resin composition containing a plant-derived low-density polyethylene resin produced by polymerizing plant-derived ethylene by a high pressure method, and the laminate film 12 for packaging materials has a biomass fraction of at least 25% as calculated from a measurement value of 14C radiocarbon dating.
(FR) L'invention concerne : un film stratifié pour matériaux d'emballage, lequel film peut contribuer à l'économie des ressources pétrolières et à la réduction des émissions de dioxyde de carbone, et est donc écologique; et un sac d'emballage, dans lequel le film stratifié est utilisé, et qui a une aptitude au traitement et des propriétés physiques, notamment la durée de vie, qui rivalisent avantageusement avec des sacs d'emballage réalisés à partir de résines à base de pétrole. Un film stratifié (12) pour matériaux d'emballage est produit par la stratification d'un film d'agent d'étanchéité (13) sur un film de base (14), le film d'agent d'étanchéité (13) étant réalisé à partir d'une composition de résine contenant un dérivé de résine polyéthylène basse densité dérivé de plantes produit par polymérisation d'éthylène dérivé de plantes par un procédé à haute pression, et le film stratifié (12) pour matériaux d'emballage présente une fraction de biomasse d'au moins 25 %, calculée à partir d'une valeur de mesure de datation au carbone radioactif 14C.
(JA) 石油資源を節約するとともに、二酸化炭素の排出量を削減する環境にやさしい包装材用積層フィルム、及びそのフィルムが用いられ、石油系樹脂の包装袋と遜色のない加工適性、及び物性、特に耐久性を有する包装袋を提供する。包装材用積層フィルム12であって、植物由来のエチレンを高圧法にて重合されて得られた植物由来の低密度ポリエチレン樹脂を含む樹脂組成物によるシーラントフィルム13と、基材フィルム14とを積層させ、包装材用積層フィルム12は、放射性炭素年代測定14Cの測定値から算定するバイオマス度を少なくとも25%有する。
