Description
本発明は、向上した分解性を有し、ラベル又は包装材料として有用な、環境保全に配慮した熱収縮フィルムに関する。
熱収縮フィルムは、例えば、ビン、電池又は電解コンデンサーにラベルを貼り付けるため、並びに容器及び他の容器を包装するためなど、広く使用されてきている。しかしながら、ポリエチレン(PE)及びポリプロピレン(PP)、ポリ塩化ビニル(PVC)、ポリスチレン(PS)、ポリエステル(PET)フィルムなどの従来の熱収縮フィルムは、それらの性能特性に関して、十分に満足のいくものではない。これらの石油由来のフィルムは、高いエネルギー消費を必要とし、大量の二酸化炭素を放出し、廃棄又は焼却の際には環境的に危険な汚染物質を生じさせる。
したがって、本発明の目的は、向上した生分解性及び熱収縮性を有し、ラベル又は包装材料として有用な、環境保全に配慮した熱収縮フィルムを提供することにある。
本発明の熱収縮フィルムは、このフィルムが脂肪族ポリカーボネートを含み、このフィルムが一軸又は二軸配向しており、70℃の熱風で10分間処理した際に少なくとも1つの方向において少なくとも30%の熱収縮を示すことを特徴とする。
二酸化炭素及びプロピレンオキシドの交互重合によって調製されるポリプロピレンカーボネート樹脂(QPAC40, Empower Materials Inc.)を、40℃で3時間に亘って乾燥させた。
二酸化炭素及びエチレンオキシドの交互重合によって調製されるポリエチレンカーボネート樹脂(QPAC25, Empower Materials Inc.)を、40℃で3時間に亘って乾燥させた。
(a)ポリカーボネートの調製
10.0g(172mmol)のプロピレンオキシドをボムリアクタ(bomb reactor)内に入れ、そこに、オニウム塩を含有する配位錯体(Co(サレン)錯体)を40ppmの量で添加した(サレン:N,N'-ビス(サリチリデン)エチレンジアミン及びビス(トリフェニルホスフィン)イミニウム塩化物)。
工程(a)で得られたポリプロピレンカーボネートを190℃で溶融押し出しした。押出物を、横方向に85℃で4回延伸し、続いて室温で冷却して、厚さが40μmである脂肪族PCフィルムを得た。
ポリマーの分子量を高めるために油浴の温度を90℃に設定した以外は例3の工程(a)の手順で、ポリプロピレンカーボネートを調製した。
ポリ塩化ビニル樹脂(TK-800, Shin-Etsu Chemical Co., Ltd.)を、ジオクチルフタラート(Shin-Nihon Chemical Co., Ltd.)に90:10の重量比で混合した。
ポリプロピレン樹脂(PP WINTEC WFX6, Nihon polypropylene Inc.)をポリエチレン樹脂(LLDPE Kernel KF271, Nihon polyethylene Inc.)に50:50の重量比でブレンドした。
ポリスチレン樹脂(TS-10, Dainippon Ink and Chemicals Inc.)を、スチレン−ブタジエンブロックコポリマー樹脂(LG 604, LG Chem. Co., Ltd.)に80:20の重量比でブレンドした。
(a)ポリマーAの調製
100モル部のジメチルテレフタレートと、180モル部のエチレングリコールとを、蒸留塔を備えたオートクレーブ内に入れ、そこに、エステル交換触媒としての酢酸マンガンをジメチルテレフタレートの重量を基準にして0.05重量%の量で添加した。反応中に生じたメタノールを除去しながら、温度を220℃まで120分かけて高めた。
エチレングリコールの代わりにトリメチレングリコールを使用したこと以外工程(a)の手順を繰り返して、0.85dL/gの固有粘度を有するポリトリメチレンテレフタレート(ポリマーB)を得た。
180モル部のエチレングリコールの代わりに90モル部のエチレングリコール及び90モル部の2,2−ジメチル−(1,3−プロパン)ジオールを使用したこと以外工程(a)の手順を繰り返して、0.64dL/gの固有粘度を有するポリエステルコポリマー(ポリマーC)を得た。
ポリマーA、B及びCを減圧下で乾燥させ、これらの含水量を0.05重量%以下に下げた。乾燥させたポリマーA、B及びCを40:25:35の比でブレンドした。
0.003gの樹脂サンプルをテトラヒドロフラン(THF)中に溶解させ、得られた溶液をELSDを備えるGPC(Waters Ltd., USA)に室温で注入し、溶出速度は1mL/分であった。
フィルムサンプルを切り出して200mm(長さ)×15mm(幅)の片とし、熱風中で10分間にわたって70℃に維持し、片の長さを測定した。以下の等式を使用し、縦方向及び横方向の各々の収縮度を計算した:
熱収縮(%)=[(熱処理前の長さ−熱処理後の長さ)/熱処理前の長さ]×100
フィルムサンプルの曇り度を、ASTM D1003に従って、透過率計(SEP-H, Nihon Semitsu Kogaku Co., Ltd.)を使用することによって測定した。
10gのフィルムサンプルをるつぼ内に入れて電子炉(HY-8000S)内に導入し、ここに、温度を600℃まで上げながら、圧縮空気を60mL/分の流量で流した。この温度条件で、排気ガスを1時間にわたってTedlar(登録商標)バッグを使用して収集した。収集前に、排気ガスをろ過して、そこから散乱性不純物粒子を除去した。収集したガスを低温エバポレータに通し、ガス分離機へ移した。このガスを、ガスクロマトグラフィ(キャリア:Heガス、 5973 inert, Agilent Technology Inc.)を使用して定性的及び定量的に分析し、揮発性有機化合物の含有量を求めた。
