Polymeric material for container

1. A container comprising:

a floor and

a container wall extending away from the floor, and the container wall and the floor cooperate to form an interior product storage region,

wherein the container wall is formed of a multi-layer material including a first layer of an insulative cellular non-aromatic polymeric material comprising high density polyethylene and a second layer comprising high density polyethylene and in contact with an outer surface of the first layer to locate the insulative cellular non-aromatic polymeric material between the second layer and the interior product-storage region,

wherein the first layer is extruded and the second layer is extruded on the first layer to cause the first layer and the second layer to contact one another,

wherein the container has a density less than about 0.4 g/cm 3 .

2. The container of claim 1 , wherein the first layer and the second layer are extruded together.

3. The container of claim 1 , wherein the second layer is about 5 mils to about 26 mils thick.

4. The container of claim 3 , wherein the container has an average collapse force in a range of about 50 pounds-Force to about 400 pounds-Force.

5. The container of claim 4 , wherein the container survives top load forces of 115 pounds-Force to about 170 pounds-Force.

6. The container of claim 3 , wherein the first layer is about 14 mils to about 130 mils thick.

7. A container comprising:

a floor and

a container wall extending away from the floor, and the container wall and the floor cooperate to form an interior product storage region,

wherein the container wall is formed of a multi-layer material including a first layer of an insulative cellular non-aromatic polymeric material comprising high density polyethylene and a second layer arranged to locate the insulative cellular non-aromatic polymeric material between the second layer and the interior product-storage region, and

wherein the insulative cellular non-aromatic polymeric material comprises regrind of previously prepared containers.

8. The container of claim 7 , wherein the regrind is free of aromatic material.

9. A method of producing a container, the method comprising:

extruding a first layer of an insulative cellular non-aromatic polymeric material comprising high density polyethylene,

extruding a second layer onto an outer surface of the first layer to contact the first layer to form a multilayer material, the second layer comprising high-density polyethylene, and

forming a container from the multilayer material,

wherein the container has a floor, a container wall extending away from the floor and the container wall and the floor cooperate to form an interior product storage region,

wherein the container has a density less than about 0.4 g/cm 3 .

10. The method of claim 9 , wherein the second layer is about 5 mils to about 26 mils thick.

11. The method of claim 10 , wherein the container has an average collapse force of in a range of about 50 pounds-Force to about 400 pounds-Force.

12. The method of claim 11 , wherein the container survives top load forces of 115 pounds-Force to about 170 pounds-Force.

13. The method of claim 9 , wherein the container has an average collapse force of in a range of about 50 pounds-Force to about 400 pounds-Force.
