Abstract

　変性ＥＶＯＨ（Ｃ）からなる層、及び（Ｃ）以外の樹脂（Ｆ）からなる層を有する多層構造体である絞出チューブであって、変性ＥＶＯＨ（Ｃ）は、未変性のＥＶＯＨ（Ａ）を、二重結合を有するエポキシ化合物（Ｂ）で変性して得られたものであり、エポキシ化合物（Ｂ）による変性量がＥＶＯＨ（Ａ）のモノマー単位に対して０．１～１０モル％であり、変性ＥＶＯＨ（Ｃ）の少なくとも一部が架橋されていて、かつ、そのゲル分率が３質量％以上であることを特徴とする絞出チューブである。これにより架橋剤の内容物への溶出が抑制されて安全性に優れ柔軟性があり、また加熱滅菌処理に付しても外観が良好であり、更に加熱滅菌処理後もガスバリア性の低下が極めて少なく、開封されるまで衛生性が保持される絞出チューブが提供される。
