Title
(EN) ADHESIVE RESIN COMPOSITION AND EASILY PEELABLE FILM
(FR) COMPOSITION DE RÉSINE ADHÉSIVE ET FILM FACILEMENT PELABLE
(JA) 接着性樹脂組成物および易剥離性フィルム
Abstract
(EN)
This adhesive resin composition contains: an ethylene-vinyl acetate copolymer (A) having a melt mass flow rate (MFR, JIS K7210:1999, 190°C, 2160 g load) of 5-40 g/10 min. or less and in which the percentage content of a structural unit derived from vinyl acetate is 3-18 mass%; a tackifying resin (B); and an ethylene-vinyl acetate copolymer (C) having a viscosity of 15,000-300,000 mPa·s as measured by using a Brookfield viscometer at 180°C.
(FR)
Cette composition de résine adhésive contient : un copolymère éthylène-acétate de vinyle (A) ayant un indice de fluidité à chaud (MFR, JIS K7210 : 1999, 190°C, 2160 g de charge) de 5 à 40 g/10 min ou moins et dans lequel la teneur en pourcentage d'une unité structurale dérivée d'acétate de vinyle est de 3 à 18 % en masse ; une résine tackifiante (B) ; et un copolymère éthylène-acétate de vinyle (C) ayant une viscosité de 15000 à 300000 mPa · s telle que mesurée à l'aide d'un viscosimètre Brookfield à 180°C.
(JA)
