A method of making a lid , the method comprising extruding a sheet comprising at least 40% by weight polypropylene that comprises rubber, thermoforming the sheet to provide a lid having a brim mount adapted to couple to a container and a closure coupled to the brim mount and adapted to at least partway close an aperture opening into the container, wherein a portion of the lid is arranged to move from a first arrangement in which the portion has a first transparency to a second arrangement in which the portion has a second transparency that is different than the first transparency, wherein a clarity of the portion of the lid in the first arrangement is between about 45% and about 95% as measured using ASTM D 1746 and a delta lightness value between a lightness of the portion of the lid in the first arrangement and the lightness of the portion of the lid in the second arrangement is about 10 or greater, wherein the sheet comprises a polypropylene impact copolymer first resin and a polypropylene impact copolymer second resin, the first resin has a first parts per million antistatic agent content and a first % by weight rubber content, the second resin has a second parts per million antistatic agent content and a second % by weight rubber content, and the first parts per million antistatic agent content is less than the second parts per million antistatic agent content and the first % by weight rubber content is less than the second % by weight rubber content so that the portion of the lid is configured to change from the first transparency to the second transparency and while minimizing migration of the antistatic agent content out of the sheet during the extruding step. extruding a sheet comprising at least 40% by weight polypropylene that comprises rubber, thermoforming the sheet to provide a lid having a brim mount adapted to couple to a container and a closure coupled to the brim mount and adapted to at least partway close an aperture opening into the container, wherein a portion of the lid is arranged to move from a first arrangement in which the portion has a first transparency to a second arrangement in which the portion has a second transparency that is different than the first transparency, wherein a clarity of the portion of the lid in the first arrangement is between about 45% and about 95% as measured using ASTM D 1746 and a delta lightness value between a lightness of the portion of the lid in the first arrangement and the lightness of the portion of the lid in the second arrangement is about 10 or greater, wherein the sheet comprises a polypropylene impact copolymer first resin and a polypropylene impact copolymer second resin, the first resin has a first parts per million antistatic agent content and a first % by weight rubber content, the second resin has a second parts per million antistatic agent content and a second % by weight rubber content, and the first parts per million antistatic agent content is less than the second parts per million antistatic agent content and the first % by weight rubber content is less than the second % by weight rubber content so that the portion of the lid is configured to change from the first transparency to the second transparency and while minimizing migration of the antistatic agent content out of the sheet during the extruding step. <EOS>
