Claim:
1. A method of producing a printed strip for use in forming an insulative cup, the method comprising the steps of forming a strip of insulative cellular non-aromatic polymeric material comprising a polypropylene base resin; printing an ink layer on the strip to form a printed strip; cutting the printed strip to form a body blank and a floor blank; compressing a first portion 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, wherein the second portion defines a fold line configured to allow the blank to be folded easily at the fold line; and forming the body blank and the floor blank into an insulative cup.
