Description
ているため、特別な装置が必要となる。また、内側ウェッブは、包装体においてシーラント層として働くが、ここにエチレン-酢酸ビニル(EVA)やアイオノマーも推奨されている。しかしながら、これら樹脂はリサイクル中に架橋などの化学変化を生じやすく、繰り返しによりゲルなどの不純物を生じやすくなる。
[塗液1]:三井化学(株)製接着剤溶液(ポリエステル系ポリウレタン樹脂溶液)
主剤:タケラックA-525(内 ウレタン樹脂の前駆体50質量%、酢酸エチル50質量%)
硬化剤:タケネートA-52(内 ウレタン樹脂の硬化剤55質量%、酢酸エチル45質量%)
溶媒:酢酸エチル
これらをA-525:A-52:酢酸エチル=9:1:165(固形分濃度3質量%)で配合した。
[塗液2]:
(a)テトラエトキシシラン(Si(OC2H5)4;以下、TEOSと略記)17.9gとメタノール10gに0.1N塩酸72.1gを加えて30分間攪拌して加水分解させた固形分5%(重量比SiO2換算)の加水分解溶液。
量1.8g/m2(ウェット)とした。以上の工程にて、積層体を得た。
Claims (1)
- 2枚の側壁用積層体と1枚の2つ折りした底用積層体からなり、周縁がシールされているスタンディングパウチの、パウチ本体部の上辺にスパウトとキャップからなる口栓を設けた口栓付きスタンディングパウチであって、前記側壁用積層体および前記底用積層体とが、
少なくともバリアフィルム層、接着剤層、シーラント層とがこの順に積層されてなり、前記バリアフィルム層が、密度0.940~0.980g/cm3の高密度ポリエチレンからなる厚さ20~40μmのフィルムと前記フィルム上に形成されたバリア層とからなり、前記シーラント層が、密度0.910~0.920g/cm3の直鎖状低密度ポリエチレンからなる厚さ100~150μmのフィルムからなり、
前記口栓が、密度0.96g/cm3以下、MFR5g/10min以上の高密度ポリエチレンからなることを特徴とする口栓付きスタンディングパウチ。
