High density polyethylene compositions having a high flow index and a bimodal composition provides an outstanding combination of processability, stiffness and ductility in rotomolded articles. The compositions have a low relative elasticity (G'/G″, measured at 0.05 rad/sec) of less than 0.03.

Rotomolding compositions with low relative elasticity

The present disclosure describes bottle closure assemblies which are made at least in part with a polyethylene composition having good processability, good organoleptic properties and good dimensional stability. The bottle closure assembly includes a cap portion, an elongated tether portion, and a retaining means portion. The retaining means portions engages a bottle neck or an upper portion of a bottle. The elongated tether portion connects at least one point on the cap portion to at least one point on the retaining means portion so as to prevent loss of the cap portion from a bottle.

Bottle closure assembly including a polyethylene composition

The present disclosure describes bottle closure assemblies which are made at least in part with a polyethylene composition having good flow properties and good resistance to environmentally induced stress cracking. The bottle closure assembly includes a cap portion, an elongated tether portion, and a retaining means portion. The retaining means portions engages a bottle neck or an upper portion of a bottle. The elongated tether portion connects at least one point on the cap portion to at least one point on the retaining means portion so as to prevent loss of the cap portion from a bottle.
