Description
本発明の一実施形態に係る多層樹脂シートの層構成は、ポリオレフィン系樹脂層/接着層/酸素バリア性樹脂層/接着層/ポリスチレン系樹脂層であり、簡素的には表皮層/接着層/酸素バリア層/接着層/下皮層との表記とする。下皮層には、本発明の多層樹脂シートや成形容器を製造する工程で発生するスクラップと称される部位を廃棄することなく、細かく粉砕して戻す若しくは熱溶融後にリペレット化して再生品として戻す層を新たに設けた構成としてもよい。
(1)ポリオレフィン系樹脂層
PP樹脂:「3080」
(Formosa Polypropylene Co.,Ltd.製、MI:8.5g/10min.(190℃、2.16kgf)、Block−PP)
(2)酸素バリア性樹脂層
エチレン−ビニルアルコール共重合体(EVOH) 「エバールJ171B」
(クラレ社製、MI:1.7g/10min.(190℃、2.16kgf)、エチレン含量32mol%)
(3)接着層
変性ポリオレフィン系重合体(変性PO) 「モディックF502C」
(三菱化学社製、MI:1.3g/10min.(190℃、2.16kgf))
(4)ポリスチレン系樹脂層
HIPS樹脂:「4241」
(Total Petrochemicals社製、
MI:4.0g/10min.(200℃、5.0kgf))
使用機器:浅野研究所社製 真空圧空成形機
加熱ヒーター:非接触式遠赤外線ヒーター
シート表面温度:シート構成により適宜シート表面温度を調整
また、多層樹脂シート及び容器の各種評価を下記の方法で行った。結果を表1に示す。
図2に示すように、シートの流れ方向(MD)と幅方向(TD)に対して45度の角度で、長さが120mmとなる切れ目を入れた後、シートの最大の反り上がり高さを金尺を用いて測定した。
図3に示すように、1個あたりの寸法が横44mm、縦55mmであり絞り比が0.5の容器を20個多列式に成形した。その多列成形品のフランジ部が下方となるよう、平坦な面の上に静置した後、平坦面から容器/フランジ部の浮き上がった部分までの最大の高さを金尺を用いて測定した。
シートの耐油性評価を図4に示す方法にて行った。
幅15mm、長さ200mmのシート試験片を固定治具の間に円弧状に歪がかかった状態で固定し、最上部に大豆油を浸したガーゼを置いた。この時、固定治具の幅は130mmとなるように固定する。また、シートの側面から大豆油が入らないように注意する。経過日数ごとにガーゼに大豆油が乾燥しない程度に滴下し、30日間連続でこの評価を実施し、シートの亀裂や破断の発生の有無につき以下の基準で判定を行った。
A:亀裂や破断の発生が一切無し
B:僅かにシート表面に亀裂の発生が見られる
C:完全にシートの破断が発生し、折れた状態が確認される
シートの酸素透過率を、以下の方法にて測定した。
[測定方法] GB/T 1038準拠
使用機器:LabThink社製 VAC−V1
測定条件:23℃×65%R.H.
サンプルセット:基本的に、容器成形後の実用性を鑑みて、シートサンプルの下皮層側から酸素が透過するような向きにサンプルをセットする。
シートの水蒸気透過率を、以下の方法にて測定した。
[測定方法] GB/T 1037準拠
使用機器:LabThink社製 W3/031
測定条件:40℃×90%R.H.
図3に挙げた容器用の成形金型を用い、熱成形する際の成形性を以下の基準で評価した。
A:成形性良好
B:成形後の容器の一部に厚みの薄い箇所が見られる
C:成形金型通りの賦形性が得られていない。若しくは成形外観不良が見られる。
