Abstract: The disclosure relates to a polypropylene-based packaging material containing an ethylene-propylene block copolymer having a phase dispersion structure in which a resin containing polypropylene as a main component is a matrix and a spindle-shaped polypropylene-based elastomer is a domain, and can provide a packaging material having all of drop impact resistance at a low temperature condition, blocking resistance, slipperiness, and flavor barrier properties.

Abstract: An electrode catalyst and a method for producing the electrode catalyst are described, in which the electrode catalyst includes catalyst metal particles containing platinum or a platinum alloy, and carrier particles supporting the catalyst metal particles. The carrier particles are made of a carbonaceous material with a BET specific surface area of 700 m2/g or more. The catalyst metal particles have an average particle size of 2.5 to 4.5 nm, and a standard deviation of the particle size of the catalyst metal particles is 1.30 nm or less. The electrode catalyst has a high initial activity and is able to maintain that activity over a long period of time.

Abstract: An article represented by a container that is formed of a thermoplastic resin blended with a metal or a metal compound that can react with a corrosive gas or a volatile sulfur compound and give a color. The thermoplastic resin includes at least one metal selected from three metals of Zn, Sn and Mn or one metal compound thereof, and a metal or a metal compound that is not any of these three metals and that can react with the corrosive gas or the volatile sulfur compound and give a color. The metal selected from the three metals or the metal compound functions as a scavenger for the corrosive gas or the volatile sulfur compound.

Abstract: [Problem] The present invention has as its object the provision of an electrode catalyst for fuel cell with a high initial activity of the electrode catalyst and able to maintain that activity over a long period of time and a method of producing the same. [Solution] The present invention relates to an electrode catalyst for fuel cell, comprising catalyst metal particles containing platinum or a platinum alloy and carrier particles supporting the catalyst metal particles, wherein the carrier particles are made of a carbonaceous material with a BET specific surface area of 700 m2/g or more, wherein the catalyst metal particles have an average particle size of 2.5 to 4.5 nm, and wherein a standard deviation of the particle size of the catalyst metal particles is 1.30 nm or less.

Abstract: A resin clip may include an anchor portion, a disk portion and an annular sealing surface formed in the disk portion. The anchor portion and the disk portion are integrally formed as a unit by single-material molding using a molding die. A portion of the anchor portion is shaped by a supplemental die part of the molding die. The sealing surface is formed by a single main die part of the molding die and has a circumferentially continuous shape.
