  • Publication number: 20240150606
    Abstract: Provided is a resin composition for a skin pack, which contains an ionomer (A) of an ethylene-unsaturated carboxylic acid-based copolymer. The ionomer (A) of an ethylene-unsaturated carboxylic acid-based copolymer satisfies the relationship 11?(X×Y×0.01)/Z. This resin composition for a skin pack contains the ionomer (A) of an ethylene-unsaturated carboxylic acid-based copolymer. The melt tension of the ionomer (A) of an ethylene-unsaturated carboxylic acid-based copolymer, as measured using a specific measurement method is 320 mN or more.

  • Patent number: 11898065
    Abstract: A resin composition for a sealant has excellent heat-sealing strength with respect to a substrate, and a reduced elution amount thereof into normal heptane. A resin composition for a sealant includes: a resin (A) which is an ethylene-(meth)acrylic acid ester copolymer in which a content of a (meth)acrylic acid ester unit is from 10% by mass to 25% by mass; and a tackifying resin (B), in which a content of the resin (A) is more than 45% by mass with respect to a total amount of resin components in the resin composition for a sealant, and a content of the tackifying resin (B) is from 0.1% by mass to 10% by mass with respect to the total amount of the resin components in the resin composition for a sealant.
