Methods and systems for packaging a product
View Patent ↗A method for applying a heat shrinkable film to a carton for forming a shape of the carton is provided. The carton includes a top panel, a bottom panel, at least one side panel extending between the top panel and the bottom panel, and a movable section that is movable between a first position and a second position. The method includes providing a heat-shrinkable but unshrunken film, 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 moving the movable section from the first position to the second position 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.
1. A package assembly, comprising:
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 comprising a cutout defined at least partially in the movable panel; and
a heat-shrinkable but unshrunken film wrapped around at least a portion of the carton including at least a portion of the movable panel,
wherein the heat-shrinkable film is operative for shrinking in response to heat, wherein the shrinking of the film moves the movable panel towards the interior space and reduces the size of the opening.
2. The package assembly of claim 1 , wherein moving the movable panel towards the interior space reduces a cross-sectional area of at least a portion of the carton.
3. The package assembly of claim 1 , 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.
4. The package assembly of claim 3 , wherein
the opening is a first opening,
the carton includes a second opening, and
moving the second movable panel towards the interior space reduces the size of the second opening.
5. The package assembly of claim 1 , wherein the heat-shrinkable film comprises a sleeve sized to receive the carton.
6. The package assembly of claim 1 , wherein
the carton includes an end,
the heat-shrinkable film extends beyond the end of the carton, such that shrinking the heat-shrinkable film brings the film into contact with at least a portion of the end of the carton.
7. The package assembly of claim 6 , wherein bringing the film into contact with at least a portion of the end of the carton substantially seals the end of the carton.
8. The package assembly of claim 6 , wherein
the end is a first end,
the carton includes a second end opposite the first end,
the heat-shrinkable 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.
9. The package assembly 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 heat-shrinkable film.
10. The package assembly of claim 1 , wherein the heat-shrinkable film comprises polyethylene, polypropylene, polyvinyl chloride, polyester, polyester glycol, nylon, oriented polystyrene, or any combination thereof.
11. A package assembly, comprising:
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; and
a heat-shrinkable but unshrunken film wrapped around at least a portion of the carton including at least a portion of the movable panel, the heat-shrinkable film being operative for shrinking in response to heat, wherein the shrinking of the heat-shrinkable film moves the movable panel towards the interior space, thereby reducing the size of the opening.
12. The package assembly of claim 11 , 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.
13. The package assembly of claim 11 , wherein moving the movable panel towards the interior space reduces the size of the interior space.
14. The package assembly of claim 11 , wherein moving the movable panel towards the interior space reduces a cross-sectional area of at least a portion of the carton.
15. The package assembly of claim 11 , 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.
16. The package assembly of claim 15 , wherein
the opening is a first opening,
the carton includes a second opening, and
moving the second movable panel towards the interior space reduces the size of the second opening.
17. The package assembly of claim 11 , wherein
the movable section is a first movable section, and
the carton includes a second movable section, wherein shrinking the heat-shrinkable film moves the second movable section into an overlapping relationship with the first movable section.
18. A package assembly, comprising:
a carton including a plurality of adjoined panels that define an interior space, the carton including and a movable section that is movable between a first position and a second position, wherein the movable section includes an opening and a movable panel, wherein the opening comprises a cutout within at least one of the plurality of side panels; and
a heat-shrinkable but unshrunken film wrapped around at least a portion of the carton including at least a portion of the movable section of the carton,
wherein the heat-shrinkable film is operative for shrinking in response to heat, the shrinking of the film being for moving the movable section from the first position to the second position, wherein moving the movable section includes moving the movable panel and reducing the size of the opening.
19. The package assembly of claim 18 , wherein moving the movable section changes a cross sectional area of at least a portion of the carton.
20. The package assembly of claim 18 , wherein
the movable section is a first movable section, and
the carton includes a second movable section, where shrinking the heat-shrinkable film moves the second movable section into an overlapping relationship with the first movable section.
