1. A method of producing a sheet for use in forming an insulative cup, the method comprising the steps of providing a strip of insulative cellular non-aromatic polymeric material;providing a film having a first side arranged to face away from the strip and an opposite second side arranged to face toward the strip;printing an ink layer on one of the first and second sides of the film to provide a printed film;laminating the printed film to the strip to form a sheet;cutting the sheet to form a body blank having a printed side and an opposite unprinted side and a floor blank having a printed side and an opposite unprinted side;compressing portions of the body blank to cause the body blank to include a first portion having a first density and a second portion having a relatively greater second density;forming a base from the body blank by coupling a portion of the printed side of the body blank to a portion of the unprinted side of the body blank, the base including a first end and an opposite second end;forming a floor from the floor blank;joining the floor to the second end of the base to establish a body that is formed to include an interior region defined by the floor and the base and to orient the floor relative to the body to cause the unprinted side of the floor blank to face toward the interior region and the printed side of the floor blank to face away from the interior region to establish the insulative cup;wherein the second portion of the body blank is the portion of the printed side of the body blank that is coupled to the portion of the unprinted side of the body blank; andwherein the insulative cellular non-aromatic polymeric material is located between the ink layer and the interior region of the insulative cup and the insulative cellular non-aromatic polymeric material comprises a polypropylene base resin having a high melt strength, a polypropylene copolymer resin, at least one nucleation agent, and gas means for expanding the resins to reduce density. 2. The method of claim 1, wherein the ink layer is printed on the second side of the film during the printing step. 3. The method of claim 1, wherein the ink layer is printed on the first side of the film during the printing step. 4. The method of claim 1, wherein the laminating step further comprises the steps of applying an adhesive to the printed film to form a skin and locating the adhesive between the ink layer and the strip of insulative cellular non-aromatic polymeric material. 5. The method of claim 1, wherein the printing step comprises the step of using a flexographic process to print the ink layer. 6. The method of claim 5, wherein the flexographically printing step comprises printing one or more colors of ink. 7. The method of claim 6, further comprising the step of selecting an ultraviolet curing ink and using the ultraviolet curing ink during the printing step. 8. The method of claim 6, further comprising the step of selecting an electron-beam curing ink and using the electron-beam curing ink during the printing step. 9. The method of claim 1, wherein the printing step comprises the step of using a rotogravure process to print the ink layer. 10. The method of claim 1, wherein the first density is about 0.175 g/cm3 and the second density is about 0.350 g/cm3. 11. The method of claim 1, wherein the film is biaxially oriented polypropylene. 12. The method of claim 1, wherein the gas means comprises carbon dioxide. 13. The method of claim 1, wherein the polypropylene base resin comprises broadly distributed molecular weight polypropylene characterized by a distribution that is unimodal. 14. The method of claim 1, wherein the polypropylene base resin further includes a polypropylene homopolymer resin.
