Claims (25)

1. A container comprising

a first layer and

a core layer comprising an insulative cellular non-aromatic polymeric material comprising

at least one polypropylene resin that is at least 85 wt % of the insulative cellular non-aromatic polymeric material,

at least one nucleating agent that is up to about 15 wt % of the insulative cellular non-aromatic polymeric material, and

wherein the first layer has been extruded onto the core layer so that the core layer and the first layer are in direct contact.

2. The container of claim 1 , wherein the polypropylene resin is a polypropylene copolymer.

3. The container of claim 1 , wherein the polypropylene resin is a polypropylene homopolymer.

4. The container of claim 1 , wherein the at least one polypropylene resin is two different polypropylene resins.

5. The container of claim 4 , wherein the ratio of the two different polypropylene resins is 50% to 50%.

6. The container of claim 1 , wherein the at least one polypropylene resin is about 90 to 99.9 wt % of the insulative cellular non-aromatic polymeric material.

7. The container of claim 6 , wherein the at least one polypropylene resin is about 95 to 99.9 wt % of the insulative cellular non-aromatic polymeric material.

8. The container of claim 7 , wherein the at least one polypropylene resin is about 96 wt % of the insulative cellular non-aromatic polymeric material.

9. The container of claim 1 , wherein the at least one nucleating agent is about 0.1 to 5 wt % of the insulative cellular non-aromatic polymeric material.

10. The container of claim 9 , wherein the at least one nucleating agent is about 0.5 to 5 wt % of the insulative cellular non-aromatic polymeric material.

11. The container of claim 1 , wherein the insulative cellular non-aromatic polymeric material further comprises regrind of the insulative cellular non-aromatic polymeric material.

12. The container of claim 1 , wherein the insulative cellular non-aromatic polymeric material further comprises a slip agent that is up to about 3 wt % of the insulative cellular non-aromatic polymeric material.

13. The container of claim 1 , wherein the at least one nucleating agent is up to 2 wt % of the insulative cellular non-aromatic polymeric material.

14. The container of claim 13 , wherein the nucleating agent is about 0.1 to 0.5 wt % of the insulative cellular non-aromatic polymeric material.

15. The container of claim 1 , wherein the insulative cellular non-aromatic polymeric material lacks talc.

16. The container of claim 1 , wherein the container has a density of about 0.5 g/cm3 to about 0.8 g/cm3.

17. The container of claim 1 , wherein the outer layer is a solid layer having a density of about 0.9 g/cm3.

18. The container of claim 1 , wherein the at least one polypropylene resin includes regrind.

19. The container of claim 1 , wherein the insulative cellular non-aromatic material further includes a blowing agent.
