Abstract
Изобретение относится к растяжимой многослойной пленке, включающей в следующем далее порядке a) первый внешний слой, содержащий по меньшей мере 98 мас.% линейного полиэтилена низкой плотности, b) первый внутренний слой, c) второй внутренний слой, d) третий внутренний слой и е) второй внешний слой, содержащий от 70 до 30 мас.% линейного полиэтилена низкой плотности и от 30 до 70 мас.% полиэтилена очень низкой плотности (ПЭОНП), где, по меньшей мере, первый внутренний слой и третий внутренний слой по отдельности содержат по меньшей мере 98 мас.% пропиленового гомополимера или 98 мас.% пропилен-этиленового сополимера и где оставшийся внутренний слой содержит по меньшей мере 98 мас.% линейного полиэтилена низкой плотности, при этом количество этилена в пропилен-этиленовом сополимере находится в диапазоне от 1 до 10 мас.%, внутренние слои, содержащие пропилен-этиленовый сополимер, составляют от 5 до 35 мас.% от многослойной пленки, внутренний слой, содержащий линейный полиэтилен низкой плотности, составляет от 30 до 60 мас.% и линейный полиэтилен низкой плотности во внутреннем слое представляет собой сополимер полиэтилена, содержащий этилен и 1-гексен.
