に富み、収納袋として成型加工するときの加工
性がよい。(2) Although it is a highly strong sheet, it is highly flexible and has good workability when molded into a storage bag.
(3) シート自体、疎水性に富み、吸湿性が低い積
層シートであるので、充填剤を乾燥状態に保持
できる。(3) Since the sheet itself is a laminated sheet with high hydrophobicity and low hygroscopicity, the filler can be kept in a dry state.
(4) シートの一面は190℃以上の粘着開始温度を
有し、他面は120〜170℃の粘着開始温度を有し
ているので、低粘着開始温度を有する面を合せ
て、120〜170℃と190℃の間の温度でヒートシ
ールすれば、容易にシールすることができ、シ
ール部の接着力も高く、かつ接着部は粗硬化す
ることなく、なお柔軟性を残している。これは
多層積層構造のうち最外層の一層でのみヒート
シールさせていることによる。(4) One side of the sheet has an adhesion starting temperature of 190°C or higher, and the other side has an adhesion starting temperature of 120 to 170°C. If heat-sealed at a temperature between 190°C and 190°C, it can be easily sealed, the adhesive strength of the sealed part is high, and the adhesive part remains flexible without being roughly hardened. This is due to the fact that only one of the outermost layers of the multilayer laminated structure is heat-sealed.
