Abstract
Description
実施例1および実施例2では、商品名Natureflexの下でInnovia Films Ltdから入手可能な23μmの食品認可されたセルロース系基材(23NK)を使用した。このNatureflex基材を、ホットメルトカーテンコーティングプロセスによって多様な生分解性コーティングで被覆した。コーティングは、Inatec GMbH、Schneiderstrasse 73、D−40764、Langenfeld、Germanyによって供給された機械を使用して実施した。
2種のバイオポリマーコーティングをこれらの実施例において使用した。バイオポリマー1は植物油モノマーを有する生分解性ポリエステルであって、バイオポリマー2は生分解性ポリエステルであった。
Bio−Polymer1は、3gsm、6gsm、および12gsmにつき
Bio−Polymer2は、3gsm、6gsm、および12gsmにつき
a)ヒートシール強度から、BIO−POLYMER1においては110℃および135℃の双方で12gsmで、BIO−POLYMER2においては110℃のみで、ポリマー−ポリマーヒートシールについて1000g/25mmより大きい平均が達成された。
b)BIO−POLYMER1においては3および6gsmの双方のコーティング重量で、ポリマー−ポリマーについて1000g/25mm超の個々のヒートシール性が認められた。
c)100g/25mm未満のきわめて低いヒートシール性が認められた。破壊モードは、これが、引裂きを伝播し、したがって、人為的に低い結果を伝える、シールにおける欠陥によるものであったことを示すはずである。
d)NK−ポリマーについて、平均ヒートシール強度は、ポリマーコーティング重量によってそれほど影響されず、BIO−POLYMER2では、双方の温度で約400g/25mmであり、BIO−POLYMER1では、110℃で約400g/25mm、135℃で約550〜600g/25mmである。
e)ヒートシール強度を、10シールの平均として記録した。各ヒートシールについて破壊モードを書き留めた。
f)破壊モードは、以下の3つの大まかなカテゴリーに分けられた:
i)層間剥離のない伝統的なシールの剥離(結果中のタイプg)。(この目的では、層間剥離は、ポリマー押出コーティングがセロハン基材から離れる場合を説明するのに使用される)
ii)シールが破壊されている溶着シール(タイプeおよびf)
iii)セロハン基材からのポリマーの層間剥離を有するシールの剥離。この場合、いくつかのシールは、シールの全長にわたって剥離されて開き、その他の場合には、シールの引裂きのように溶着への前兆となった。(タイプa〜d)
g)大半のヒートシールは、シールの引裂きまたはポリマー層の層間剥離のいずれかによってフィルムを破壊する結果となった。
h)結果より、BIO−POLYMER1ポリマーの主な破壊モードは上記のカテゴリーii)であるとみなされうる。一方、BIO−POLYMER2では、それはカテゴリーiii)である。
i)ピリジンを使用して、引き離されたヒートシールを分析することにより、PVdCは、層間剥離されたポリマー上に認められ、セロハンフィルム上にはないので、破壊点は、セロハン−PVdC境界面にあることが示唆される。
2)ホットタック性
a)すべての場合において、フィルム試料は150gの重量で合格し、良好なホットタック性を示した。
3)ホットシールジョーレリース性、典型的な規格値−30g/5cm2以下
a)JRは、双方のポリマーについて所与の温度で、コーティング重量の増加と共に上昇した。
b)BIO−POLYMER1は、対応するBIO−POLYMER2の試料よりも良好に機能した。
c)JRは、双方のポリマーについて所与のコーティング重量で、温度の上昇と共に低下した。
a.バイオポリマーがヒートシールの両面上のNKから層間剥離しているシールの剥離。
b.片面の端から残りのシール領域へと引き裂かれ始めているシールの剥離。
c.シールが引き裂かれ始めているが、外側のバイオポリマー層が層間剥離して1枚の完全なフィルムとして離れているような完全な引裂きは達成されていない。
d.シールが完全に引き裂かれる前に該NKの両面からバイオポリマーが層間剥離している。
e.シールが開口部の最初の10%の範囲内で完全に引き裂かれている(溶着シール)。
f.シールが最初に剥離した後に完全に引き裂かれている(溶着シール)。
g.通常のタイプのシールの剥離。
40μmの食品認可された再生セルロース系フィルム基材を使用した。このフィルム基材を、標準的な押出被覆プロセスによって多様な生分解性コーティングで被覆した。使用したコーティング機械は、該フィルム基材の上方に吊着された平ダイに、溶融したポリマーを供給している押出機で構成されていた。このダイから押出されたポリマーのカーテンは、2つのローラーの間のニップの直前に該フィルム基材と接触した。これらのローラーうちの1つは、水で冷却された平滑仕上げのクロムローラーであった。ポリマーコーティングは、冷却されたローラーと接触して、固体化した。
