Flexible packaging structure with a built-in opening and reclose feature
A flexible packaging laminate is formed to have a built-in opening and reclose feature by forming the laminate as a two-part structure having an outer structure joined in face-to-face relation with an inner structure. Score lines are formed in both structures to enable an opening to be formed through the laminate by lifting an opening portion (e.g., a flap or the like) of the two structures out of the plane of the laminate. The score line through the outer structure defines a larger opening than the score line through the inner structure, such that a marginal region of the outer structure extends beyond the edge of the opening portion of the inner structure. A pressure-sensitive adhesive is used to re-adhere the marginal region to an underlying surface of the inner structure adjacent the opening through the laminate.
Flexible material for flexible package
A flexible, stackable, recloseable container for storing a quantity of products comprising a plurality of walls defined by a first sheet and a second sheet attached to at least a portion of the first sheet. The second sheet extends over at least three of the walls. The opposing container walls each have a sealed portion and one or more tucks, the tucks comprising a portion of the first sheet tucked toward the interior volume. A portion of the second sheet defines a recloseable feature located over an opening for reclosing the container. The second sheet includes a line of reduced strength at or adjacent at least a boundary adjacent the tucks and disposed between the opposing container walls each having the sealed portion and an adjacent container wall. The second sheet can include a hinge about which the recloseable feature pivots from closed position to open position.
Polymeric films and bags
The present invention is directed to a method of incrementally stretching polymeric film formed from a blown film extrusion process. The present invention is further directed to a polymeric bag formed from an incrementally stretched polymeric film. The incremental stretching is performed on a collapsed polymeric bubble via a pair of intermeshing rollers. The incrementally stretched polymeric film may be stretched only along a portion of its width. The polymeric bag may be a drawstring trash bag with an extended hem where only the extended hem of the bag or the body of the bag comprises incrementally stretched polymeric film.
REINFORCED THERMOPLASTIC BAG WITH EXTENDED HEM SKIRT
The present disclosure relates to strata 2-ply drawstring trash bags implementing a J-flap extended hem to provide increased top-of-bag strength. In one or more embodiments, the J-flap extended hem includes a 2-ply web folded back on itself (e.g., during a hem folding operation to enclose the drawstring within a hem channel). In one or more implementations, a hem seal secures the 2-ply web to an inside surface of the trash bag. At least one ply of the 2-ply web fold-over extends past the hem seal and is additionally secured to the inside surface of the trash bag via one or more hem skirt seals. For reduced material consumption in certain embodiments, the J-flap extended hem of the present disclosure imparts added strength using only one ply of the 2-ply web fold-over. In some embodiments, at least one ply of the 2-ply web fold-over includes ring-rolled portions to add top-of-bag strength.
THERMOPLASTIC FILMS AND BAGS WITH ENCAPSULATION-BASED DELAYED ODOR CONTROL AND METHODS OF MAKING THE SAME
The present disclosure relates to a thermoplastic film that includes a plurality of ribs and a plurality of web areas that separate and connect the ribs. The thermoplastic film further includes an encapsulated odor control component that includes an odor control active encapsulated within a plurality of encapsulants. The encapsulants can be configured to delay a release of the odor-control active until activated. Further, the encapsulated odor control component can be applied across the plurality of ribs and the plurality of web areas, which can be configured to cause the encapsulants to activate in phases.
Plastic bag making apparatus and method
In a plastic bag including a triangular flap which has a folded hypotenuse and an open hypotenuse, a flow path is formed by the folded hypotenuse or the open hypotenuse to discharge air or gas through the flow path.
A PANEL FOR A FLEXIBLE PACKAGE
A panel for a flexible package (100), and a method and system for forming the panel is provided. The panel comprises a first laminate having an open-area; a second laminate extending from a top edge to a bottom edge; and a third laminate, the third laminate sealed with the first laminate to cover the open-area, and the top edge and the bottom edge of the second laminate sealed between the first laminate and the third laminate such that area between the top edge and the bottom edge of the second laminate remains free forming a loop with the panel. The panel preferably forms a side-gusset (102) of a flexible packaging pouch, wherein the loop can be used as a handle (110) to carry the flexible package.
SEMI-RIGID CARTON POUCH PACKAGE
Paper-based packages and methods of making the same are disclosed. In one example, a semi-rigid package comprises: a base, a first side portion, and a second side portion. The base comprises two opposed major walls and two longitudinal side walls opposed to each other. The first side portion and a second side portion are integrally formed with the base. The two side portions are respectively connected to the base along the longitudinal direction, and each side portion comprises two opposed side panels, two tapered corner portions opposed to each other, and a closure in a transverse direction. Each side panel is connected to the adjacent major wall along a transverse line, and the two opposed side panels are jointed to form the closure. At least one of the side portions may be substantially compacted and form a substantially flat transverse side wall.
BAG-MAKING AND PACKAGING APPARATUS
A bag-making and packaging apparatus includes a bag-making and packaging unit, a film feeding unit, a splicing device, and a control unit. The control unit allows a bag-making operation to continue by utilizing an auto-feeding function that feeds to the bag-making and packaging unit a film F spliced by the splicing device to take the place of a film F currently being fed to the bag-making and packaging unit. When the control unit judges that at least one of the film feeding unit and the splicing device is malfunctioning in a case where the control unit is utilizing the auto-feeding function, the control unit stops the auto-feeding function and executes a non-auto-feeding mode. The non-auto-feeding mode allows the bag-making operation to be continued by the bag-making and packaging unit and a film roll holding unit that is operable among plural film roll holding units.
FLEXIBLE PACKAGING STRUCTURE WITH A BUILT-IN OPENING AND RECLOSE FEATURE
A flexible packaging laminate is formed to have a built-in opening and reclose feature by forming the laminate as a two-part structure having an outer structure joined in face-to-face relation with an inner structure. Score lines are formed in both structures to enable an opening to be formed through the laminate by lifting an opening portion (e.g., a flap or the like) of the two structures out of the plane of the laminate. The score line through the outer structure defines a larger opening than the score line through the inner structure, such that a marginal region of the outer structure extends beyond the edge of the opening portion of the inner structure. A pressure-sensitive adhesive is used to re-adhere the marginal region to an underlying surface of the inner structure adjacent the opening through the laminate.
