本明細書における元素周期表に対する全ての言及は、CRC Press,Inc.,2003によって出版され、著作権所有される元素周期表を指すものとする。また、群(複数可)に対するいかなる言及も、群を番号付けするためのIUPACシステムを使用する、この元素周期表において反映される群または群に対するものとする。反対のことが述べられているか、文脈から暗に示されているか、または本技術分野で慣習的ではない限り、全ての部及びパーセントは、重量に基づく。米国特許慣行の目的で、本明細書において言及されるいかなる特許、特許出願、または出版物の内容も、特に合成技術の開示、定義(本明細書に提供されるいかなる定義とも矛盾しない程度まで)、及び本技術分野の一般知識に関して、それらの全体がこれにより参照によって組み込まれる(またはそれらの同等の米国版が参照によって同様に組み込まれる)。
本可撓性容器は、第1の複層フィルム及び第2の複層フィルム、ならびに付属部を含む。一実施形態において、可撓性容器8は、付属部10を含む。付属部10は、図1に示されるようにベース12及び上部14を有する。
ゼロ超〜最大130J/gまでのΔHについて、
(D)TREFを使用して分画されるときに40℃〜130℃の間で溶出する分子量分画を有し、分画が、同一の温度間で溶出する同等のランダムエチレンインターポリマー分画のモルコモノマー含有量よりも、少なくとも5パーセント高いモルコモノマー含有量を有するという点を特徴とし、ここで、該同等のランダムエチレンインターポリマーは、同一のコモノマー(複数可)を有し、エチレン/α−オレフィンインターポリマーのメルトインデックス、密度、及び(ポリマー全体に基づく)モルコモノマー含有量の10パーセント以内の、メルトインデックス、密度、及びモルコモノマー含有量を有する、または
Tmは、80℃、または85℃、または90℃から、95℃、または99℃、または100℃、または105℃〜110℃、または115℃、または120℃、または125℃までである。
本可撓性容器は、第1の複層フィルム及び第2の複層フィルムを含む。一実施形態において、可撓性容器8は、図1に示されるように、第1の複層フィルム16(前方フィルム)及び第2の複層フィルム18(後方フィルム)を含む。用語「第1の複層フィルム」及び用語「前方フィルム」は、同じ意味で使用される。用語「第2の複層フィルム」及び用語「後方フィルム」は、同じ意味で使用される。
前方フィルム16及び後方フィルム18は、共通外周縁20の周囲にシールされる。可撓性容器8は、外周縁20の一部分に沿って位置する付属部シール22を含む。付属部シール22は、図3に示されるように、前方フィルム16と後方フィルム18との間に挟まれたベース12、(ii)前方フィルム16とベース12との間の溶着部24、(iii)後方フィルム18とベース12との間の溶着部26、(iv)前方フィルム16と後方フィルム18との間の溶着部28、ならびに(v)ベース12の対向する側から延在する原位置ウィングレット30及び原位置ウィングレット32を含む。
本可撓性容器は、ボックスパウチ、ピローパウチ、口付きのk−sealされたパウチ、口付きで横にまちが付いたパウチであり得る。容器内に装着された付属部(口もしくは弁または他のもの)の位置は、2つのフィルムの間にシールが存在するところであればどこであってもよく、すなわち、例えば、上部、側部、または更には、前方パネルに対して底部のまちのシールにおける底部上であってもよい。換言すると、付属部シール22は、可撓性容器上の2つのフィルムが交わり、一緒にヒートシールされるところのどこかに位置するか、またはさもなければ形成され得る。付属部シール22の好適な位置の非限定的な例には、可撓性容器の上部、底部、側部、角、まち面積が含まれる。
6つの付属部、付属部1〜6を提供する。各付属部1〜6の寸法は同一であり、材料のみが付属部にわたって異なる。各付属部1〜6は、0.8mmの厚さ及び12mmのベース直径を有するベース壁を有する。
各付属部、付属部1〜6を、シール層が互いに向き合った状態で、(表1の)フィルム1の2つの対向するフィルム間に配置する。
