摘要： 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 I 2 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 I 2 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.

摘要： The present disclosure provides a multilayer film containing at least three layers, including (A) a core layer containing a high density polyethylene (HDPE) having a density from 0.940 g/cc to 0.980 g/cc; and (B) skin layers on opposite sides of the core layer. Each skin layer includes (i) a propylene/ethylene copolymer with from greater than 0 wt% to 5 wt% units derived from ethylene comonomer; (ii) from 3,000 to 3,500 ppm of a slip agent; and (iii) from 4,000 to 10,000 ppm of an antiblock agent.

摘要： Embodiments of polyethylene formulations and articles comprising polyethylene formulations are dislcosed. The polyethylene formulation may include from 45 wt.% to 90 wt.% of an MDPE having a density of from 0.930 g/cc to 0.950 g/cc and a melt index (I2) from 0.05 g/10 min to 0.5 g/10 min; from 10 wt.% to 50 wt.% of a polyethylene composition having a density from 0.910 g/cc to 0.936 g/cc and a melt index (I2) from 0.7 g/10 min to 1.0 g/10 min; and from 0.5 wt.% to 5% of a masterbatch composition. The polyethylene composition may comprise a first polyethylene fraction area in a temperature range of 45°C to 87°C of an elution profile via improved comonomer composition distribution (iCCD) analysis method and a second polyethylene fraction area in a temperature range of 95°C to 120°C of an elution profile via iCCD.

摘要： The present invention relates to a flexible container (10). In an embodiment, the flexible container includes a first flexible film (12) superimposed on an opposing second flexible film (14). The first flexible film and the second flexible film are sealed along a common peripheral edge (16) to form an inner container having a closed chamber. The first flexible film and the second flexible film each has an outermost layer comprising an ethylene-based polymer. Each outermost layer is a surface-treated layer having a surface energy from 33 mN/m to 36 mN/m. The flexible container includes a peel sleeve (22, 24) superimposed on each respective outermost layer and along the common peripheral edge. The flexible container includes a release material (26) located between the peel sleeve and each outermost layer along the common peripheral edge. The release material releasably attaches the peel sleeve to the inner container.
