一方、耐熱性基材層としてのPETフイルム(東洋紡績(株)製「エスペットフイルム(12μm)」)に、酸素ガスバリヤー性基材層としてのポリ(メタ)アクリル酸素ポリマー・糖類の混合ポリマーコート(1μm)した耐熱基材層と酸素ガスバリヤー基材層とが一体になった積層体を準備した。
[サーマルラミネート法による積層]
サーマルラミネート法による積層は図1に示す装置を用いて行った。図1において、11は第一繰出しロールで、前記シーラント基材層(HDPE層1とLLDPE層2)と接着性樹脂層3からなる積層体4を繰出すものであり、21は第二繰出しロールで、前記酸素ガスバリヤー基材層(ポリ(メタ)アクリル酸系ポリマー・糖類の混合ポリマーコート層5)と耐熱基材層(PETフイルム6)からなる積層体7を繰出すものである。30は加熱部で、前記積層体4の接着性樹脂層3の表面を加熱するものであり、40は接着部で、接着性樹脂層3にポリ(メタ)アクリル酸系ポリマー・糖類の混合ポリマーコート層5を圧着して接着させるものである。
輸液バッグ用積層フイルム8を用いてHDPE層1を最内層として三方をヒートシールを行い14cm×18cmの輸液用の袋を作製した。
この作製した袋に蒸留水250mlを充填し(抽出液量と材料面積の比は250ml/14×18×2cm2=0.5ml/cm2)、日本薬局方14改正「溶出物試験」に準拠して121℃、1時間加熱し冷却後、内容液の紫外部吸収スペクトルを測定(株式会社日立サイエンスシステムズ製『U−1100型日立レシオビーム分光光度計』)した。その時のUV吸光度(−logT)を表1に示す。
一方、L−トリプトフアンを含有するアミノ酸輸液を調製し、滅菌前後60℃−2ヶ月保存後の波長430nmに於ける透過率を測定してその着色度合を測定した。
モダンアシナリー(株)製、3種3層の共押出し機(主押出し機90mmΦ、幅副押出し機50mmΦ、2基)を用い、主押出し機にLLDPE樹脂(日本ポリオレフィン(株)製「ハーモックスLL NC574R」)を投入し、副押出し機の一方にHDPE樹脂(日本ポリケム(株)製「ノバテックHD・LY20」)を投入し、もう一方の副押出し機にエチレン−不飽和カルボン酸無水物−不飽和カルボン酸エステル共重合体93%と高密度ポリエチレン7%から成る接着性樹脂(日本ポリオレフィン(株)製「レクスパールET−184M」)を投入し、260℃で共押出しを行ってHDPE層(10μm)/LLDPE層(90μm)/接着性樹脂層(15μm)のフイルムを作製した。次いで、このフイルムの接着性樹脂層にコロナ放電加工を行って0.03W・分/m2のコロナ処理を行った。
耐熱性基材層としてのO−NYフイルム(東洋紡績(株)製「ハーデンフイルム N1130(15μm)」に、酸素ガスバリヤー性基材層としてのポリ(メタ)アクリル酸系・糖類の混合ポリマーコート(1μm)した耐熱基材層と酸素ガスバリヤー基材層とが一体になったフイルムを準備した。
サーマルラミネートは実施例1と同様に、図1に示す装置を用いて行い、ラミネート条件も実施例1と全く同様に行って、O−NYフイルム層(15μ)/ポリ(メタ)アクリル酸系ポリマー・糖類の混合ポリマーコート層(1μm)/接着性樹脂層(15μm)/LLDPE層(90μm)/HDPE層(10μm)の輸液バック用積層フイルムを作製した。
この積層フイルムを用い実施例1と同様の大きさの輸液用の袋を作製した。
実施例1と全く同様に操作してUV吸光度を測定した。UV吸光度を表5に示す。
実施例1と全く同様にアミノ酸輸液を調製し、実施例1と全く同様に操作してアミノ酸輸液入り輸液バッグを得た。高圧蒸気で121℃−20分間の滅菌した後その滅菌前後、60℃−2ヶ月保存テスト後の外観及び着色度と滅菌後の輸液バッグ(本積層フイルム)の酸素ガスバリヤー性を測定した。外観及び着色度を表6に示す。酸素ガスバリヤー性を表7に示す。
