nは、上記にて列挙された分子量を与えるのに必要とされる重合度であり、典型的には14〜28の範囲内である)。
(i)1種または複数のジオール;1種または複数のジカルボン酸;および1種または複数のポリ(アルキレンオキシド)グリコールから得られたモノマー単位を含有するコポリエステルを含むポリマー材料の第1の層を提供するステップと、
(ii)第1の層の表面に、ヒートシール可能な第2のポリマー層を提供するステップと
を含む。
εB(%)=(破断点伸長/L0)×100
と定義される(式中、L0は、グリップ間でのサンプルの元の長さである)。
(単層フィルム)
一連のコポリエステルを、表1に示されるテレフタル酸、エチレングリコール、および第3の成分を使用して作製した。第3の成分(ポリ(アルキレンオキシド)グリコールまたは第2のジカルボン酸)のモル%は、最終的なコポリエステル中のジオールおよび/または2価酸部分のモル%としてそれぞれ表1に示す。コポリエステルは、(テレフタル酸のジメチルエステルを使用する)エステル交換経路を介し、または直接エステル交換を介した従来の技法を使用して作製した。
複合フィルムも、共押出しによって製造し、この場合、第1の層は、上記にて示された通気性コポリエステルであり、第2の層は、通気性のヒートシール可能なポリマー層であった。コポリマー材料は、以下に示すコポリマーP1、P2、P3、P4、HS1、およびHS2を成形するために、テレフタル酸、エチレングリコール、および第3および任意選択で第4の成分を反応させることによって得られた。モル%の値は、最終的なポリマーで測定されたものである。
P2:グリコール部分の37%のレベルにあるPEG 1000
P3:グリコール部分の31%のレベルにあるPEG 3350
P4:グリコール部分の33.5%のレベルにあるPEG 3350;および酸部分の1.4%のレベルにあるスルホ−イソフタル酸
HS1:酸部分の18%のレベルにあるイソフタル酸
HS2:グリコール部分の10%のレベルにあるPEG 400;および酸部分の18%のレベルにあるイソフタル酸
コポリエステルを、別々の押出し機から供給された別々の流れを用いて一つのチャネルの共押出しアセンブリに共押出した。ポリマー層を、フィルム成形ダイに通して、水冷回転急冷ドラム上に様々なライン速度で押し出すことにより、非晶質流延複合押出し物が得られた。流延押出し物を、約50から80℃の範囲の温度に加熱し、次いで約3:1の順方向の延伸比で縦方向に延伸した。このポリマーフィルムを、約110℃の温度でステンタオーブン内に通し、そこでシートを横方向に、その元の寸法の約4倍に延伸し、次いで210から225℃の間の温度で熱硬化した。フィルムの最終的な厚さは23μmであり、この場合、第2の(ヒートシール可能な)層は、第1の層の厚さの10〜15%であった。フィルムは透明であり、例えば実施例6は、ヘーズが4.5%であった。フィルムのWVTRを表2に示す。
