DEODORIZING FILM FOR HEAT STERILIZATION TREATMENT, AND DEODORIZING PACKAGING MATERIAL AND DEODORIZING PACKAGE PRODUCED FROM THE DEODORIZING FILM FOR HEAT STERILIZATION TREATMENT
PROBLEM TO BE SOLVED: To provide a deodorizing film for a heat sterilization treatment, which exhibits an excellent deodorizing effect even when subjected to a heat sterilization treatment and includes a sealant layer in an outermost surface layer on at least one side, and a packaging material and a package using the deodorizing film.SOLUTION: The deodorizing film for a heat sterilization treatment includes at least a sealant layer in an outermost layer on one side, in which the sealant layer comprises a heat-sealing resin, a powdery hydrophobic zeolite and a powdery inorganic odor decomposing agent. The heat-sealing resin has a softening point of 110°C or higher and 175°C or lower； the hydrophobic zeolite has a SiO2/Al2O3 molar ratio of 30/1 or more and 8000/1 or less； the inorganic odor decomposing agent is prepared by kneading or depositing a metal oxide or a metal salt in or on an inorganic substance； and the total content of the hydrophobic zeolite and the inorganic odor decomposing agent in the sealant layer is 0.3 mass% or more and 15 mass% or less.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】本発明は、加熱殺菌処理を施しても、優れた消臭効果を発揮する、少なくとも片面の最表層にシーラント層を含む加熱殺菌処理用消臭フィルム、及びそれを用いた包装材料、包装体を提供することを課題とする。【解決手段】少なくとも、片面の最表層にシーラント層を含む加熱殺菌処理用消臭フィルムであって、前記シーラント層は、ヒートシール性樹脂と、粉状の疎水性ゼオライトと、粉状の無機臭気分解剤とを含み、前記ヒートシール性樹脂の軟化点は、１１０℃以上、１７５℃以下であり、前記疎水性ゼオライトは、ＳｉＯ2／Ａｌ2Ｏ3モル比が、３０／１以上、８０００／１以下であり、前記無機臭気分解剤は、金属酸化物または金属塩を、無機物に混錬または担持させたものであり、前記シーラント層中の、前記疎水性ゼオライトと前記無機臭気分解剤との合計の含有量が、０．３質量％以上、１５質量％以下である、加熱殺菌処理用消臭フィルム。【選択図】図１
