摘要： Provided are non-breathable films including specific polymer blends, and methods for making such films. The films comprise an anhydride and/or carboxylic acid functionalized ethylene/alpha-olefin interpolymer, a linear low density polyethylene, and an inorganic filler. The method of manufacturing the film comprises extruding an anhydride and/or carboxylic acid functionalized ethylene/alpha-olefin interpolymer, a linear low density polyethylene, and an inorganic filler to form the film and stretching the film. The films according to embodiments disclosed herein can exhibit low WVTR values and improved modulus while also incorporating significant amounts of inorganic filler at low gauges.

摘要： Provided are absorbent layers and articles, and methods for making absorbent layers and articles. The absorbent layer is suitable for use in an absorbent article and may include a nonwoven that includes bicomponent fibers and superabsorbent polymer material interconnected within the nonwoven. The absorbent layer according to different embodiment may include a three-dimensional random loop material with superabsorbent polymer material adhered to the three-dimensional random loop material. Absorbent articles may comprise the absorbent layer according to embodiments of the present disclosure. The method for making the absorbent layer includes providing a nonwoven and dosing the nonwoven with superabsorbent polymer material.
