Description
この発明は、引掻耐性および防湿性の、酸素または二酸化炭素に対するバリアコーティング、および随意に空にするのを容易化するための親水性の内部コーティングを有するプラスチック容器に関する。さらには、本発明はかかる容器の製造方法に関する。
ポリプロピレン容器の被覆
フッ素供給のために不動態化された、清浄で乾燥した鋼製の圧力シリンダーにおいて、高真空(<1torr)で引くことによって、加圧された処理ガスのベッセルをまず準備した。これに、窒素中20%(容積)のF2を、ゲージ圧が1061kPa(154psi)に達するまで添加した。その後、乾燥した、オイルを含まない圧縮空気を、ベッセルがゲージ圧3.4MPa(500psi)に達するまで添加した。このシリンダーをローラー装置上で水平に横たえ、且つ、48時間、回転させてガスを均質に混合した。
フッ素供給のために不動態化された、清浄で乾燥した鋼製の圧力シリンダーにおいて、高真空(<1torr)で引くことによって、加圧された処理ガスのベッセルをまず準備する。これに、窒素中20%(容積)のF2を、ゲージ圧が703kPa(103psi)に達するまで添加した。その後、乾燥した、オイルを含まない圧縮空気を、該ベッセルがゲージ圧3.4MPa(500psi)に達するまで添加した。その後、このシリンダーをローラー装置上で水平に横たえ、且つ、48時間、回転させてガスを均質に混合した。フッ素酸化をバッチ式で、内容積56l(2ft3)を有する鋼製ベッセル内にて行った。
PPおよびPET製の500mlボトルのためのプリフォームを、未処理で、または上述の前処理をして、使用した。
PVOH含有率18〜21mol%およびポリ酢酸ビニル含有率1〜4mol%を有する、ポリビニルブチラール(PBV) MOWITAL SB 30HH (Kuraray Europe GmbH)の10質量%のエタノール溶液を調製し、且つ、該プリフォームを溶液中に浸漬させることによって被覆した。過剰なコーティング液を、回転させることによって除去し、そして被覆されたプリフォームを終夜、室温で乾燥させた。
Kuraray Europe GmbH製のMOWIOL 28−99(鹸化度99%を有するPVA)の10質量%の水溶液を調製し、且つ、ベースコートを備えたプリフォームを該溶液中に浸漬させることによって被覆した。過剰なコーティング液を、回転させることによって除去し、そして被覆されたプリフォームを終夜、室温で乾燥させた。
その後、PVOH含有率18〜21mol%およびポリ酢酸ビニル含有率1〜4mol%を有する、ポリビニルブチラール(PBV)としてのMOWITAL SB 30HH(Kuraray Europe GmbH)の10質量%のエタノール溶液を調製し、且つ、段階a)およびb)において既に被覆されたプリフォームを、溶液中に浸漬させることによって被覆した。過剰なコーティング液を、回転させることによって除去し、そして被覆されたプリフォームを終夜、室温で乾燥させた。
Claims (12)
