Abstract: An object of the present invention is to provide a polyethylene-based-resin composition from which a film can be obtained which has excellent moldability even in a case where an inorganic compound is added, and has excellent bag-making processability and film strength; and a polyethylene-based-resin packaging material formed of the polyethylene-based-resin composition. In a polyethylene-based-resin composition containing an inorganic compound and an ethylene-?-olefin copolymer, at least a part of the ethylene-?-olefin copolymer is an ethylene-?-olefin copolymer A in which ?-olefin has 6 to 8 carbon atoms and a melt flow rate is 0.8 g/10 min or more and 4.0 g/10 min or less, the amount of the inorganic compound is 50% by mass or more and 80% by mass or less, and the amount of the ethylene-?-olefin copolymer A is 10% by mass or more and 50% by mass or less.

In a polyethylene-based resin composition containing an inorganic compound and an ethylene-?-olefin copolymer, the amount of a resin component is 25% by mass or more and less than 90% by mass, a proportion of the ethylene-?-olefin copolymer in the resin component is 50% by mass or more, and a proportion of an ethylene-?-olefin copolymer A polymerized with a metallocene-based catalyst in the ethylene-?-olefin copolymer is 10% by mass or more.

Abstract: Provided is a green tea-containing beverage including: (A) green tea; (B) at least one selected from the group consisting of phytic acid, tartaric acid, and gluconic acid; and (C) at least one selected from the group consisting of ascorbic acid, a salt of ascorbic acid, erythorbic acid, and a salt of erythorbic acid, wherein the green tea-containing beverage has a copper content of 0.3 mg/L or more. Preferably, the concentration of the constituent (B) is 0.05-2.5 g/L. Preferably, the concentration of the constituent (C) is 0.2-5 g/L. Preferably the green tea-containing beverage further includes alcohol. Also provided is a method for preventing discoloration of a green tea-containing beverage, the method including: incorporating the constituents (B) and (C) in the green tea-containing beverage; and further incorporating copper so as to give the copper content of 0.3 mg/L or more.
