Embodiments of the present disclosure are directed to drawtapes for trash bags, wherein the drawtape comprises a multilayer polymer film having an improved stiffness.

Collapsed bubble drawtape film for improved elastic and stiffness performance in trash bags

Embodiments of thermoplastic bags which yield elasticity and stiffness include a first drawtape disposed within the first channel, wherein the first drawtape comprises a linear low density polyethylene having a density of from 0.902 g/cc to 0.920 g/cc, and a second drawtape disposed within the second channel, wherein the second drawtape comprises a high density polyethylene having a density of from 0.940 g/cc to 0.965 g/cc.

Dual drawtape trash bags having improved elastic and stiffness performance

A multilayer blown film having an inner layer, a first outer layer, and a second outer layer, wherein the inner layer comprises an ethylene-based polymer having a MWCDI value greater than 0.9, and a melt index ratio (I10/I2) that meets the following equation: I10/I2&#x2265;7.0&#x2212;1.2&#xd7;log (I2); and the first outer layer and the second outer layer independently comprise a polyethylene composition which comprises the reaction product of ethylene and, optionally, one or more alpha olefin comonomers, wherein the polyethylene composition is characterized by the following properties: (a) a melt index, I, of from 0.1 to 2.0 g/10 min; (b) a density of from 0.910 to 0.930 g/cc; (c) a melt flow ratio, I/I, of from 6.0 to 7.6; and (d) a molecular weight distribution, (Mw/Mn) of from 2.5 to 4.0.
