A method in accordance with claim 1 wherein providing a heat-shrinkable but unshrunken film further comprises: providing a heat-shrinkable but unshrunken film having a leading end and a trailing end unattached to the leading end; bonding the leading end of the film to the carton; wrapping the film in an unheated condition around at least a portion of the carton including at least a portion of the movable section of the carton; and bonding the trailing end of the film to at least one of the carton and the film itself. 3. A method in accordance with claim 2 wherein the carton further includes at least one seam wherein the at least one seam is formed when at least two panels are adhered to one another, and wherein bonding the leading end of the film to the carton further comprises bonding the leading end of the film within a seam of the carton such that the leading end is not visible. 4. A method in accordance with claim 1 wherein providing a heat-shrinkable but unshrunken film further comprises providing a heat-shrinkable but unshrunken film in the form of a pre-formed sleeve, the sleeve having an opening sized to receive the carton. 5. A method in accordance with claim 4 wherein providing a heat-shrinkable but unshrunken film in the form of a pre-formed sleeve further comprises: inserting the carton into the sleeve opening; and moving the movable section from the first position to the second position to form a shape of the carton by heating the heat-shrinkable sleeve to shrink the heat-shrinkable sleeve into contact with at least a portion of the movable section. 6. A method in accordance with claim 1 wherein providing a heat-shrinkable but unshrunken film further comprises providing a heat-shrinkable but unshrunken film that includes a marking thereon. 7. A method in accordance with claim 1 wherein providing a heat-shrinkable but unshrunken film further comprises providing a heat-shrinkable but unshrunken film having a marking thereon including graphics for the carton, wherein the graphics are applied using an opaque ink. 8. A method in accordance with claim 1 wherein providing a heat-shrinkable but unshrunken film further comprises providing a heat-shrinkable but unshrunken film having a marking thereon including graphics for the carton, wherein the graphics are applied using a translucent ink such that the film graphics coordinate with additional graphics printed on the carton. 9. A method in accordance with claim 1 wherein providing a heat-shrinkable but unshrunken film further comprises providing a heat-shrinkable but unshrunken film manufactured from at least one of polyethylene, polypropylene, polyvinyl chloride, polyester, polyester glycol, nylon, and/or oriented polystyrene. 10. A method in accordance with claim 1 wherein the carton extends a height measured between the top and the bottom of the carton, and the film extends a height greater than the carton height, and wherein wrapping the film further comprises: wrapping the film in an unheated condition around the carton including the movable section of the carton wherein the film extends a distance outwardly from at least one of the top and the bottom of the carton; and heating the heat-shrinkable film to shrink the heat-shrinkable film into contact with at least a portion of the at least one of the top and the bottom of the carton for providing at least one of a tamper resistance measure, a moisture barrier, and a sifting barrier. 11. A method in accordance with claim 1 wherein the carton extends a height measured between the top and the bottom of the carton, and the film extends a height less than the carton height, and wherein wrapping the film further comprises wrapping the film in an unheated condition around a portion of the carton including at least a portion of the movable section of the carton. 12. A method in accordance with claim 1 wherein moving the movable section further comprises: providing a plurality of heat-shrinkable film types including heat-shrinkable films having different shrink orientations and percentages; and moving the movable section from the first position to the second position using the plurality of the heat-shrinkable film types to form a shape of the carton by heating the heat-shrinkable film to shrink the heat-shrinkable film into contact with at least a portion of the movable section. 13. A method in accordance with claim 1 wherein moving the movable section further comprises applying a plurality of different heating temperatures to at least a portion of the heat-shrinkable film for controlling a degree of shrinkage of the film. 14. A method in accordance with claim 1 further comprising: controlling a degree of shrinkage of the film by at least one of using a specific type of film, controlling a temperature of the heating, and targeting the heating on the film; and moving the movable section from the first position to the second position to form a shape that includes at least one cut-out in the carton such that a product included within the carton is visible. 15. A method in accordance with claim 1 wherein said moving the movable section further comprises changing a cross sectional area of at least a portion of the carton. 16. A method in accordance with claim 1 wherein the movable section comprises a first movable section and a second movable section, and said moving the movable section further comprises overlapping the second movable section with the first movable section. 17. A system for applying a heat shrinkable film to a carton for forming a shape of the carton, said system comprising: a carton comprising a top panel, a bottom panel, a plurality of side panels extending between the top panel and the bottom panel, and a movable section that is movable between a first position and a second position; a wrapping device configured to wrap a heat-shrinkable but unshrunken film in an unheated condition around at least a portion of the carton including at least a portion of the movable section of the carton, wherein the movable section including at least one opening having a size and at least one movable panel wherein the at least one opening is a cut-out defined within at least one of the plurality of side panels; and a heating device configured to heat at least a portion of the heat-shrinkable film into contact with at least a portion of the movable section to move the movable section from the first position to the second position to form a shape of the carton, wherein moving the movable section includes moving the at least one movable panel and reducing the size of the at least one opening of the movable section. 18.
