Abstract

Изобретение относится к новой соэкструдированной многослойной структуре, которая имеет степень вытяжки, превышающую предельную степень вытяжки каждого из полимерных слоев, экструдированных по отдельности. Настоящее изобретение также относится к способу получения соэкструдированной многослойной структуры. Соэкструдированная многослойная структура, получаемая способом, описанным в настоящей заявке, позволяет получать с высокой скоростью пленки, филаментные нити или нетканые материалы, полученные прядением из расплава, с низким весом с использованием обычного экструзионного оборудования. Соэкструдированная многослойная структура, в частности, пригодна в качестве внешних слоев подгузника или покрытий гибкой упаковки.
