Description
添付の表は、オレンジジュース(Valio)とシミュレータを使用する実施例を示す。シミュレータは、pHが0.01MのHClによって3.8の値に調節された1リットルの溶液中、リモネン100μlと界面活性剤(Tween80)1.2gとを含むD−リモネンの水溶液であった。基板は、300g/m2の坪量を有する液体包装用ベースボードからなる。基板の他の表面は、LDPEにより20g/m2のコーティング量でコーティングされた。表に示されるように、基板の対向面(それはジュースまたはシミュレータに対向する)は、異なる方法でコーティングされた。検討されたすべてのサンプルの酸素バリア層は、類似したEVOH層を含んでいた。LPDEのグレードは、他の表面のそれと同じであった。結合層は、ポリエチレン系グラフト化接着性ポリマーを含むものであった。第1サンプルのEMAポリマー(そのコーティング重量は31g/m2である)は、EMA系接着性ポリマーであるBynel4288であった。第2サンプルのEMAポリマー(その重量:29g/m2)は、市販のEI−valoy1609ACであり、そのMA含量は9モル%であった。当然のことであるが、EMA層で使用される前記ポリマー製品は、唯一の実現可能な製品ではなく、大部分のポリマーメーカーは対応するEMA製品を販売している。第3と第4のサンプル(それらはEMA層を含まなかった)は、参照サンプルであった。
様々なサンドイッチ構造によるオレンジジュースからのD−リモネンのスカルピングは、また、時間の関数として、つまり、保存期間またはインキュベーション時間が、検討されたサンプルによるD−リモネンのスカルピングにどのように影響を及ぼしたかが検討された。一般に、インキュベーション時間は、ジュースが試験材料から製造された容器内に保存される時間である。一般に、スカルピング試験の持続時間は、42時間であるが、ここでは2つの他の試験期間(すなわち、72時間と168時間)もまた使用された。
いろいろなサンドイッチ構造によるD−リモネンのスカルピングは、時間の関数として測定された。リモネン含有液体は、オレンジジュースと実施例1によるシミュレータを含んでいた。試験期間は、42時間,72時間、および168時間であった。
本発明によるボードのEMA表層の生産条件への適用性は、包装ブランクの処理のための重要な要因、すなわち摩擦特性を比較することによって検討された。試験では、従来の構造を表わすLDPE層と比較して、静止摩擦および動的摩擦の両方の値にわずかな違いがあることが観察された。しかしながら、その違いは有意ではなかった。したがって、その加工性は、生産への適用可能性の必要条件を満たすものである。
