shrinking the heat-shrinkable film moves the second movable panel towards the interior space.
4. The method of claim 1 , wherein
the heat-shrinkable film has a leading end and a trailing end unattached to the leading end, and
the method further comprises
bonding the leading end of the heat-shrinkable film to the carton, and
bonding the trailing end of the heat-shrinkable film to at least one of the carton and the heat-shrinkable film itself.
5. The method of claim 4 , wherein bonding the leading end of the heat-shrinkable film to the carton comprises concealing the leading end of the heat-shrinkable film within a seam formed between at least two panels joined to one another.
6. The method of claim 1 , wherein the heat-shrinkable film comprises a sleeve sized to receive the carton.
7. The method of claim 6 , further comprising inserting the carton into the sleeve before heating the heat-shrinkable film.
8. The method of claim 1 , wherein the heat-shrinkable film includes a marking thereon.
9. The method of claim 1 , wherein the heat-shrinkable film includes graphics comprising an opaque ink.
10. The method of claim 1 , wherein the heat-shrinkable film includes graphics comprising a translucent ink.
11. The method of claim 10 , wherein the graphics on the heat-shrinkable film coordinate with graphics printed on the carton.
12. The method of claim 1 , wherein the heat-shrinkable film comprises polyethylene, polypropylene, polyvinyl chloride, polyester, polyester glycol, nylon, oriented polystyrene, or any combination thereof.
13. The method of claim 1 , wherein
the carton includes an end,
the heat-shrinkable film extends beyond the end of the carton, and
shrinking the heat-shrinkable film brings the film into contact with at least a portion of the end of the carton.
14. The method of claim 13 , wherein bringing the film into contact with at least a portion of the end of the carton provides a tamper resistance measure, a moisture barrier, a sifting barrier, or any combination thereof.
15. The method of claim 13 , wherein
the end is a first end,
the carton includes a second end opposite the first end,
the heat-shrinkable but unshrunken film extends beyond the second end of the carton, and
shrinking the heat-shrinkable film brings the film into contact with at least a portion of the second end of the carton.
16. The method of claim 1 , wherein
the heat-shrinkable film is a first heat shrinkable film of a plurality of heat-shrinkable films wrapped around at least a portion of the carton, and
at least one of the heat-shrinkable films has a different shrink orientation, a different shrink percentage, or a combination thereof than at least one other of the heat-shrinkable films.
17. The method of claim 1 , wherein heating the heat-shrinkable film to shrink the film 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.
18. The method of claim 1 , further comprising controlling a degree of shrinkage of the film by using a specific type of heat-shrinkable film, controlling a temperature of the heating of the heat-shrinkable film, targeting the heating of the heat-shrinkable film, or any combination thereof.
19. A system for forming a shaped carton, comprising:
a carton including a plurality of adjoined panels that define an interior space, the plurality of adjoined panels comprising a movable panel, the carton including a movable section including
the movable panel, and
an opening comprising a cutout defined at least partially in the movable panel
a wrapping device configured to wrap a heat-shrinkable but unshrunken film around at least a portion of the carton including at least a portion of the movable panel; and
a heating device configured to heat the heat-shrinkable film, thereby
shrinking the heat-shrinkable film,
moving the movable panel towards the interior space, thereby reducing the size of the opening from a first size to a second size less than the first size, and
forming the shaped carton.
20. The system of claim 19 , wherein
the heat-shrinkable film includes a leading end and a trailing end unattached to the leading end, and
the wrapping device is further configured to
bond the leading end of the heat-shrinkable film to the carton, and
bond the trailing end of the heat-shrinkable film to at least one of the carton and the heat-shrinkable film itself.
21. The system of claim 20 , wherein the wrapping device is further configured to conceal the leading end by joining the leading end of the heat-shrinkable film within a seam formed between at least two panels adhered to one another.
22. The method of claim 19 , wherein
the heat-shrinkable film comprises a sleeve dimensioned to receive the carton, and
the wrapping device is further configured to insert the carton into the sleeve.
23. A method of forming a shaped carton, comprising:
providing a carton including a plurality of adjoined panels that define an interior space, the carton including a movable section comprising
a movable panel, and
an opening defined at least partially by a cutout disposed along an edge of the movable panel;
wrapping a heat-shrinkable but unshrunken film around at least a portion of the carton including at least a portion of the movable panel; and
heating the heat-shrinkable film, thereby
shrinking the heat-shrinkable film,
moving the movable panel towards the interior space, thereby reducing the size of the opening from a first size to a second size less than the first size, and
forming the shaped carton.
24. The method of claim 23 , wherein the opening is further defined by a cutout disposed along an edge of a panel adjacent to the movable panel, the cutout of the movable panel and the cutout of the panel adjacent to the movable panel being adjacent to one another.
25. The method of claim 23 , wherein moving the movable panel towards the interior space reduces the size of the interior space from a first size to a second size less than the first size.
26. The method of claim 23 , wherein moving the movable panel towards the interior space reduces a cross-sectional area of at least a portion of the carton.
27. The method of claim 23 , wherein
the movable panel is a first movable panel,
the plurality of adjoined panels includes a second movable panel, and
shrinking the heat-shrinkable film moves the second movable panel towards the interior space.
28. The method of claim 23 , wherein
the heat-shrinkable film has a leading end and a trailing end unattached to the leading end, and
the method further comprises
bonding the leading end of the heat-shrinkable film to the carton, and
