ETHYLENE-VINYL ALCOHOL COPOLYMER-CONTAINING RESIN COMPOSITION, FILM, LAMINATE, PACKAGING MATERIAL, VACUUM THERMAL INSULATOR, FILM PRODUCTION METHOD, AND LAMINATE PRODUCTION METHOD

摘要

Provided is a resin composition that achieves superior appearance characteristics such as a color of a film end (or a roll end) after melt molding, film-breaking resistance, blocking resistance, vapor deposition defects-inhibiting properties, and adhesive strength of a vapor deposition layer. The resin composition contains: an ethylene-vinyl alcohol copolymer; inorganic particles; and an aliphatic carbonyl compound having 3 to 8 carbon atoms, in which the content of the inorganic particles is 50 ppm or greater and 5,000 ppm or less, the aliphatic carbonyl compound is at least one selected from the group consisting of a saturated aldehyde, an unsaturated aldehyde and a saturated ketone, and the content of the aliphatic carbonyl compound is 0.01 ppm or greater and 100 ppm or less. The inorganic particles preferably contain a metal element which is at least one selected from the group consisting of silicon, aluminum, magnesium, zirconium, cerium, tungsten and molybdenum.
