Abstract

A találmány lágy, texturált, magas hőmérsékleten mérettartómikropórusos fóliára vonatkozik, amely kb. 45-60 tömeg% töltőanyagot,továbbá lineáris kissűrűségű polietilént és nagysűrűségű polietiléntvagy más hőálló polimert tartalmaz. A texturált, magas hőmérsékletenmérettartó mikropórusos fóliát előállító eljárás során a fentikeverékből fóliát extrudálnak, és a fóliát kapcsolt görgők közöttnyújtják. A nyújtott fóliát hőkezelik, a hőkezelt fóliát újrafelmelegítik, és esetleg a felmelegített fóliát dombornyomó hengerekközött átvezetve dombornyomásos mintázattal látják el. Ó
