Description
本出願は2016年3月8日付韓国特許出願第10−2016−0027783号および2017年3月7日付韓国特許出願第10−2017−0029106号に基づいた優先権の利益を主張し、当該韓国特許出願の文献に開示された全ての内容は本明細書の一部として含まれる。
PEC樹脂70重量%にEVA樹脂(LG化学、EC33018 Grade、VA含量33重量%)30重量%(合計100重量%)をよく混合して、40℃の真空オーブンに12時間以上乾燥し、二軸押出機を用いてコンパウンディング(compounding)してペレットを確保した後、3層フィルムの製造が可能なブローン(blown)フィルム設備の内層に前記ペレットを適用したフィルムを製造し、外層はLLDPE(LG化学 S1020L Grade)フィルムが製造されるように共押出ブローン(blown)工程を行って厚さ約50μmの3層フィルムを製造した後、3層フィルムの各層別剥離が起こるか観察し、このフイルムでASTM D 3985の方法で酸素透過度を測定した。
EVAの含量を40wt%にしてPECとブレンディング(blending)したことを除いては、実施例1と同様な方法で多層フィルムを製造し、物性評価を行った。
前記実施例1でEVAの含量を10wt%にしてブレンディング(blending)したPECを3層の内層に適用したフィルムを製造し、外層をLLDPEを適用して共押出を行って厚さ約50μmの3層フィルム(PE−PECコンパウンド−PEフィルム)を製造した後、3層フィルムの各層別剥離が起こるか観察した。
前記実施例1でEVAの含量を15wt%にしてブレンディング(blending)したPECを3層の内層に適用したフィルムを製造し、外層をLLDPEを適用して共押出を行って厚さ約50μmの3層フィルム(PE−PECコンパウンド−PEフィルム)を製造した後、3層フィルムの各層別剥離が起こるか観察した。
前記実施例1でEVAをブレンディング(blending)せずにPECを単独で3層の内層に適用したフィルムを製造し、外層をLLDPEを適用して共押出を行って厚さ約50μmの3層フィルム(PE−PEC−PEフィルム)を製造した後、3層フィルムの各層別剥離が起こるか観察した。
前記実施例1でPECを使用せずにLLDPE単独で厚さ約50μmのフィルムを製造して、このフイルムで米国材料試験協会ASTM D 3985の方法で酸素透過度を測定した。
