Description
しかしながら、エチレン/ビニルアルコール共重合体又はアクリロニトリル/メチルアクリレート共重合体は高価であり、その代替となるものが求められていた。さらに、無延伸ポリエステルを用いた場合でも、包装材料としてさらなる性能向上、特にヒートシール性と非収着性の高いレベルでの両立が求められていた。
(1)内層フィルムがイソフタル酸成分の共重合比率が10モル%~20モル%のイソフタル酸変性ポリエチレンテレフタレート樹脂から成るヒートシール面側層とイソフタル酸成分の共重合比率が0モル%~5モル%のイソフタル酸変性ポリエチレンテレフタレート樹脂から成る層の2層を少なくとも有する多層フィルムであること、
(2)貼付剤用の包装材であること、
(3)貼付剤が、経皮吸収性薬物を含有する粘着剤層を支持体の片面に形成してなる経皮吸収製剤であることが好ましい。
(4)上記の包装材にて貼付剤を包装してなる包装構造であること、
(5)貼付剤が、経皮吸収性薬物を含有する粘着剤層を支持体の片面に形成してなる経皮吸収製剤であることが好ましい。
ヒートシール性を有するポリエチレンテレフタレート系樹脂として用いるイソフタル酸成分の共重合比率が10モル%~20モル%であるイソフタル酸変性ポリエチレンテレフタレート樹脂は、油状成分の非収着性に優れていると共に、優れたヒートシール性を有する。このため、前記ポリエチレンテレフタレート樹脂は、貼付剤中の油状成分の包装材料への移行を防止できる包装材のヒートシール面を構成する材料として優れている。イソフタル酸の共重合比率が10モル%未満の場合、製膜時の結晶化によりヒートシール性が低下する。また共重合比率が20モル%を超える場合は非収着性が低下する。
さらには、ヒートシール性を有するポリエチレンテレフタレート系樹脂からなる内層フィルムがイソフタル酸成分の共重合比率が10モル%~20モル%、好ましくは12モル%~18モル%、特に好ましくは14モル%~16モル%のイソフタル酸変性ポリエチレンテレフタレート樹脂から成るヒートシール面側層とイソフタル酸成分の共重合比率が0モル%~5モル%、好ましくは0.1モル%~4モル%、特に好ましくは1モル%~3モル%のイソフタル酸変性ポリエチレンテレフタレート樹脂から成る層(すなわち、基材フィルムと対向させる側の層)の2層を少なくとも有する多層フィルムであることが特に好ましい。
イソフタル酸成分の共重合比率が10モル%~20モル%の比較的高変性率のポリエチレンテレフタレートは、結晶性が低いためにヒートシール特性に優れると共に、優れた非収着性を有するものの、イソフタル酸成分の共重合比率が0モル%~5モル%の低変性率のポリエチレンテレフタレートはさらに高い非収着性を有する。また、低変性率のポリエチレンテレフタレートはペットボトル用材料として汎用的に大量に使用されているため安価に調達可能であり、経済性に優れる。すなわち、ポリエチレンテレフタレート系樹脂からなる内層フィルムを上記の多層構成とすることにより、ヒートシール特性、非収着性および経済性に優れた内層フィルムが実現出来るのである。
内層フィルムには、ヒートシール特性および非収着性を損なわない範囲で各種添加剤を添加することも出来る。添加剤としては、酸化防止剤、紫外線吸収剤、加水分解防止剤、防カビ剤、硬化触媒、可塑剤、顔料、充填剤、滑剤等が挙げられる。
内層フィルムの厚みは10μm~30μm、特に15μm~28μmが好ましい。これ以上の厚みでは、非収着性が低下したり、引き裂き性に問題が生じたりする恐れがあり、またこれ以下の厚みではヒートシール強度が低下したり、包装材の腰が損なわれ商品性に問題を来す恐れがある。内層フィルムが多層構成の場合、ヒートシール面側層の厚みは2~20μmが好ましく、3~10μmが特に好ましい。低変性率のポリエチレンテレフタレート層の厚みは、ヒートシール面側層の厚みと合わせて所望の内層フィルム全体の厚みを得られるように適宜設定することができるが、好ましくは10~28μmであり、特に好ましくは15~25μmである。
内層フィルムはTダイ成形やインフレーション成形等公知の製膜方法で製膜することができる。その際、熱溶融状態の膜が急速冷却により固化されることが好ましい。急速冷却することにより、樹脂の結晶化を抑制し、ヒートシール特性に優れたフィルムが得られる。
また、内層フィルムは無延伸あるいは低倍率で延伸された状態が好ましい。高倍率で延伸されたポリエチレンテレフタレートは配向結晶化によりヒートシール性が失われるため好ましくない。
さらに酸素や水蒸気の透過性を防ぐ目的として、ガスバリア層を積層する事も好ましい。ガスバリア層としては、アルミニウム箔が使用できる。アルミ箔は酸素や水蒸気に対するバリヤ性だけではなく、遮光性にも優れており好適に使用できる。ガスバリア層を積層する場合、その厚みは2~20μmが好ましく、5~10μmが特に好ましい。
積層体は、三方又は四方シールの通常のパウチ類、ガセット付パウチ類、スタンディングパウチ類、ピローパウチ類などに製袋することにより包装袋とすることができる。製袋は公知の製袋法で行うことができる。
貼付剤の形態としては、平面状の扁平な形態であり、平面形状は、略矩形のほか、三角形、五角形等の多角形、すなわち略直線で輪郭付けられる形状や、楕円、円形等の曲線で輪郭づけられる形状、それらの組み合わせなどが挙げられるが、これらに限定されるものではない。
貼付剤の大きさは、貼付剤の用途や適用箇所などに応じて、適宜選択することができる。例えば、貼付剤の形状が略矩形である場合、一般的には、その一辺の長さが15mm~90mmであり、他辺の長さも15mm~90mmである。
(1) ヒートシール強度
ヒートシール試験装置(テスター産業株式会社製)を使用し、シール時間0.8秒、シール圧を2kgf/cm2と固定し、シール温度を変更してシール界面の温度を測定しながら試験片を作製した。ヒートシール強度の測定はJIS-Z1707に準じ、23℃、50%RH環境下で、精密万能試験機オートグラフAG-IS(島津製作所株式会社製)にて測定した。フィルムの流れ方向(MD)に300mm/minの速度で引っ張り、最大試験力(N/15mm)をヒートシール強度とし、シール界面温度に対してプロットしてヒートシール曲線を作成した。ここで、ヒートシール強度が1N/15mmに達するシール界面温度をシール発現温度とし、シール界面温度110℃でのヒートシール強度と共にヒートシール特性の評価に用いた。シール発現温度90℃以下および110℃でのシール強度15N/15mm以上の両条件を満足する包装材をヒートシール特性良好とした。
(2) 油状成分の非収着性
包装材6cm×10cmの試験片をミリスチン酸イソプロピル雰囲気中に50℃で6日間静置した後、60mlヘキサンにて50℃で24時間抽出し、抽出液中のミリスチン酸イソプロピルをガスクロマトグラフィーにて定量した。結果は比較例1の包装材の測定結果を100とした場合の相対値で示した。
基材フィルムとして12μm二軸延伸ポリエチレンテレフタレート(PET)フィルムと7μmアルミ箔のドライラミネートフィルム、内層フィルムとして5μmイソフタル酸変性PET(イソフタル酸成分共重合比率15モル%)および20μmイソフタル酸変性PET(イソフタル酸成分共重合比率2モル%)から成る25μm無延伸2層PETフィルムを用いた。基材フィルムのアルミ箔側と内層フィルムの20μmイソフタル酸変性PET(イソフタル酸成分共重合比率2モル%)側を対向させて2液硬化型ウレタン系接着剤を用いてドライラミネーション法により積層し、包装材を得た。得られた包装材の評価結果を表1に示す。
内層フィルムとして30μmLDPEフィルム(タマポリ製AJ-3)を使用した以外は実施例1と同様にして包装材を得た。評価結果を表1に示す。
内層フィルムとして30μmPANフィルム(タマポリ製ハイトロンBX)を使用した以外は実施例1と同様にして包装材を得た。評価結果を表1に示す。
内層フィルムとして25μm無延伸単層イソフタル酸変性PET(イソフタル酸成分共重合比率2モル%)を使用した以外は実施例1と同様にして包装材を得た。評価結果を表1に示す。
