Abstract:
(EN) Provided as an ethylene-vinyl alcohol copolymer pellet that is capable of suppressing the occurrence of fish eyes even with a single layer film of an ethylene-vinyl alcohol copolymer is an ethylene-vinyl alcohol copolymer composition pellet containing a boron compound, which is configured such that: the boron compound content in the pellet surface layer part is 1.7 ppm or less per weight of the pellet in terms of boron; and at least one fish eye inhibitor component is contained at a specific ratio.
(FR) L’invention concerne des pastilles de copolymère éthylène – alcool vinylique qui permettent d’inhiber l’apparition d’yeux de poisson, y compris dans le cas d’un film à couche simple d’un copolymère éthylène – alcool vinylique. Plus précisément, l’invention concerne des pastilles de composition de copolymère éthylène – alcool vinylique qui comprennent un composé bore. La teneur en composé bore dans une partie couche superficielle, est inférieure ou égale à 1,7ppm pour la masse des pastilles en termes de bore. En outre, les pastilles de l’invention comprennent au moins un composant inhibant les yeux de poisson en proportion spécifique.
(JA) エチレン-ビニルアルコール系共重合体の単層膜でも、フィッシュアイの発生を抑制できるエチレン-ビニルアルコール系共重合体ペレットとして、ホウ素化合物含有するエチレン-ビニルアルコール系共重合体組成物ペレットであって、当該ペレット表層部のホウ素化合物含有量が、ホウ素換算で当該ペレット重量あたり1.7ppm以下であり、かつ特定割合のフィッシュアイ抑制成分を少なくとも一つ含有するエチレン-ビニルアルコール系共重合体組成物ペレットを提供する。
