Elastic Drawstring for Trash Bags / Poly-America, L.P. The present invention is directed toward an improved elastic drawstring for use with a trash bag. The elastic drawstring is comprised primarily of a two-component polyethylene blend. The first polyethylene component is a linear low-density polyethylene (LLDPE) having a density of 0.915 g/cc or less, with a preferred range of between 0.900 g/cc and 0.915 g/cc. In certain preferred embodiments, the density of the first polyethylene component is approximately 0.906 g/cc. The second polyethylene component is a low-density polyethylene (LDPE) having a density of between 0.915 g/cc and 0.929 g/cc. In a preferred embodiment, the second polyethylene component has a density of approximately 0.918 g/cc. |
