Polymeric material for container

A formulation comprising at least one high density polyethylene (HDPE) base resin, a chemical blowing agent, a physical blowing agent, a nucleating agent, a slip agent, and a colorant, wherein

• (a) the HDPE base resin is about 80 wt % to about 99.9 wt % of the formulation,
• (b) the chemical blowing agent is up to about 2 wt % of the formulation,
• (c) the nucleating agent is up to about 15 wt % of the formulation,
• (d) the slip agent is up to about 3 wt % of the formulation,
• (e) the colorant is up to about 4 wt % of the formulation, and wherein the formulation has a density of about 0.4 g/cm3 to about 0.9 g/cm3, and wherein the formulation is non-aromatic.
