Abstract: Embodiments of the present disclosure are directed to multilayer silo bags that may include a tube comprising at least two layers, a first open end, a second open end, and a first region and a second region disposed between the first and second end. One or more of the at least three layers may comprise an ethylene/alpha-olefin interpolymer having a density of 0.90 g/cc to 0.965 g/cc and an I2 of 0.1 to 6.0 g/10 minutes, a low density ethylene-based polymer having a density of 0.917 g/cc to 0.935 g/cc and an I2 of 0.1 to 2.0 g/10 minutes, or combinations thereof. The first region may have a thickness of at least 10% greater than a thickness of the second region. The first region may have a surface area that is at least 50% of an overall surface area of the multilayer silo bag.

Abstract: Provided are bicomponent fibers with improved curvature. The bicomponent fiber comprises a first region and a second region. The first region comprises a first polyethylene composition and second region comprises a second polyethylene composition, wherein the first polyethylene composition has a crystallization temperature (Tc) greater than a crystallization temperature (Tc) of the second polyethylene composition. The bicomponent fiber can be used to form a nonwoven.

Abstract: Embodiments of the present disclosure are directed to multilayer silo bags that may include a tube comprising at least two layers, a first open end, a second open end, and a first region and a second region disposed between the first and second end. One M or more of the at least three layers may comprise an ethylene/alpha-olefin interpolymer having a density of 0.90 g/cc to 0.965 g/cc and N an I2 of 0.1 to 6.0 g/10 minutes, a low density ethylene-based polymer having a density of 0.917 g/cc to 0.935 g/cc and an I2 of 0.1 to 2.0 g/10 minutes, or combinations thereof. The first region may have a thickness of at least 10% greater than a thickness of the second region. The first region may have a surface area that is at least 50% of an overall surface area of the multilayer silo bag.
