Abstract: Methods are provided for making slider-operated fasteners for use in reclosable plastic bags using at least a double index and dual unit operations. The methods involve forming two preseals, forming two notches within the preseals, applying two sliders into the previously formed notches, and applying two end stops proximate the previously applied sliders by having the various stations perform their respective functions, either simultaneously or at generally the same time, on different parts of the fastener spaced approximately at a double index. Also provided are methods of producing finished bags by applying the slider-operated fastener to a flat web of plastic film and conveying the web to a vertical or a horizontal form-fill-seal machine.

Abstract: The present invention relates to a process used for packaging a product in a web of material that has a zipper attached thereto. The process includes providing a web of material having first and second edges and a zipper including first and second interlocking members. The first and second interlocking members of the zipper are interlocked together. The first interlocking member of the zipper is attached to the web at an intermediate portion of the web between the first and second edges of the web. The second interlocking member has an attachment region that is facing away from the web. One edge of the web is folded away from the zipper and toward the other edge of the web. Unit operations are performed on the zipper to create zipper segments from the zipper while the zipper is exposed. Each of the zipper segments is associated with an individual food package made from the web.

Abstract: A slider is adapted for use with a reclosable fastener for bags containing material. The reclosable fastener includes a first track and a second track. The first track includes a first profile, while the second track includes a second profile. The first and second profiles are releasably engageable to each other. At least one of the first and second profiles has an interior portion. The slider comprises a body that includes a top, a first side, a second side and a separation member on an underside of the top. The separation member is adapted to open and close the fastener and includes a slider finger that extends generally downwardly from the top. The slider finger extends into an interior portion of the first profile so as to assist in removing material trapped in the interior portion of the first profile when closing the reclosable fastener.

Abstract: A method and apparatus for making reclosable plastic bags is provided. In the method and apparatus, a fastener is attached to a moving flat web of plastic film, preferably in the direction of web movement and near the center of the web. A plurality of sliders are mounted to the fastener either before or after the fastener is attached to the flat web, but prior to conveying the web to a FFS machine. The flat web, with the slider-operated fastener already attached thereto, is then conveyed to a vertical or horizontal FFS machine where the flat web is formed into bags, and the bags are successively filled and sealed.

Abstract: A slider-operated fastener comprises first and second opposing tracks including respective first and second interlocking profiles and respective first and second fins extending downward from the respective first and second profiles. The first and second fins are sealed to each other by a plurality of spaced preseals. After generating each preseal, a notch is formed in the profiles and upper portions of the fins at the generated preseal. To install a slider onto the fastener, the slider is initially positioned within the respective notch and then threaded onto the fastener in response to relative movement of the slider and the fastener. Either before or after the steps of forming each preseal and respective notch and installing the respective slider, the fastener is attached to a moving web of plastic film. The fastener-carrying web is later folded and sealed to form individual plastic bags.

Abstract: A method of applying a slider to a fastener-carrying web of plastic film. The fastener includes interlockable profiles and fins depending from the respective profiles. One of the fins is attached to the web of plastic film such that the profiles are immediately adjacent to the web. The fastener is folded away from the web about the attached fin such that the profiles and proximate portions of the fins are oriented at an angle, preferably about 90 degrees, relative the web. Because the profiles and proximate fin portions are oriented at an angle relative to the web, they can be easily accessed and controlled for applying the slider to the profiles and performing other fastener-related operations.

Abstract: A child resistant/elderly friendly slider closure arrangement for plastic bags includes a finger actuated member that must be actuated before the closure can be opened. The finger actuated member is pivotally mounted on the body of a slider in a location to engage the closure or another slider.

Abstract: A reclosable package includes a pair of opposing walls, a reclosable seal and a barrier partition. The pair of opposing wall panels are joined along a pair of opposing sides and a bottom bridges the opposing sides to create a receptacle space having a mouth end opposite the bottom. The reclosable seal extends along the mouth end and includes first and second opposing reclosable elements. The first and second reclosable elements are releasably engageable to each other. The barrier partition comprises at least a first layer that is substantially impermeable to at least one of oxygen, nitrogen and carbon dioxide. The barrier partition extends substantially across the pair of opposing wall panels in the receptacle space.

Abstract: A fill-through-the-top reclosable package includes first and second opposing body panels joined to each other along a pair of sides and a bottom bridging the pair of sides. The package is provided with a reclosable fastener extending alone a package top disposed opposite the bottom. The fastener includes first and second opposing tracks. The first track includes a male profile, while the second track includes a female profile adapted to releasably interlock with the male profile. To provide tamper evidence, the first and second tracks may be joined to each other along an area of weakness. When making the package, the first track is first attached to the first panel, the package, the first track is first attached to the first panel, the package is filled with a product via a fill opening between the second track and the second panel, and then the second track is attached to the second panel.
