Title:
酸素吸収性樹脂組成物及び脱酸素性多層体
Document Type and Number:
Japanese Patent JP4449120
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an oxygen-absorbing resin composition having concealed uneven dispersion of a deoxygenating agent and excellent in light-shielding properties, and a deoxygenating multilayer body and a deoxygenating packaging container comprising the same. SOLUTION: This oxygen-absorbing resin composition comprises 100 pts.wt. of a deoxygenating agent having a particle size of 1-200 μm, 0.1-30 pts.wt. of at least one white inorganic filler selected from the group consisting of carbonate salts, sulfate salts, and hydroxides and oxides of group II and III metals in the periodic table and having a particle size of 3-100 μm and 30-1,000 pts.wt. of a thermoplastic resin. The deoxygenating multilayer body or the title deoxygenating packaging container is composed of the same. The deoxygenating packaging container is good in appearance and prevents deterioration of materials contained therein not only by oxygen but also by light thereby enabling a long-term preservation of foods and drugs.
