The double-wall container of claim 17, wherein the expanded insulation further comprises a natural binder material, wherein the natural binder material is a starch-based material, and wherein the microspheres are disposed in the starch-based material. 25. The double-wall container of claim 17 where the inner and outer walls are of a paper stock material. 26. The double-wall container of claim 25 where the paper stock material is provided in roll or web form. 27. The double-wall container of claim 26 where the paper stock material is flexible to be provided in roll or web form. 28. The double-wall container of claim 25 where the paper stock material of the inner wall is different from the paper stock material of the outer wall. 29. A double-wall container, comprising: an inner wall;an outer wall;a single layer of expanded insulation engaging both the inner wall and the outer wall to create air gaps between the inner wall and the outer wall, the single layer of expanded insulation being formed from an insulating material including expandable microspheres having an activation temperature not exceeding 190° F.; andan adhesive that is different than the expanded insulation and that adheres the inner wall and the outer wall together with the single layer of expanded insulation including expanded, non-ruptured microspheres therebetween. 30.
