Title:
MULTILAYER FILMS HAVING A LAYER COMPRISING A POLAR MATERIAL AND METHODS OF PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2021/026137
Kind Code:
A8
Abstract:
Multilayer films having a layer including a medium density polyethylene having (a) a first polyethylene fraction having a single peak in a temperature range of 45 °C to 87 °C in an elution profile via improved comonomer composition distribution (iCCD); and (b) a second polyethylene fraction having a single peak in a temperature range of 95 °C to 120 °C via iCCD analysis. The polyethylene composition has a density of 0.924 g/cm3 to 0.936 g/cm3 and a melt index (I2) of 0.25 g/10 minutes to 2.0 g/10 minutes, a first polyethylene fraction area comprises at least 40% of the total area of the elution profile, a ratio of the first polyethylene fraction area to the second polyethylene fraction area is 0.75 to 2.5, and the width of the single peak of the second polyethylene fraction at 50 percent peak height is less than 5.0 °C.
