Title: (EN) BREATHABLE ELASTIC POLYMERIC FILM LAMINATE
(JA) 通気性の弾性ポリマーフィルム積層体
Abstract:
(EN) PROBLEM TO BE SOLVED: To provide an elastomeric breathable three-dimensional composite laminate and a method for producing the same.

SOLUTION: A carrier material 10 is supplied onto a top surface of continuous portions of an elastomeric film 12 to form the laminate. A pressure differential is applied to a bottom surface of the film for a time sufficient for three-dimensional apertured structures 36 to be formed in the film.

【課題】エラストマーの通気性三次元複合積層体およびそれを製造する方法を提供する。
【解決手段】キャリヤー材料10がエラストマーフィルム12の連続部分の頂面上に供給されて前記積層体を形成する。
三次元の開口の開いた構造36がフィルム中に形成されるために、十分な時間、フィルムの底面へ圧力差動がかけられる。
