    Abstract: A fastener arrangement includes a fastener, a slider, and an injection-molded end stop. The fastener includes first and second tracks. The first track includes a first profile, and the second track includes a second profile for interlocking with the first profile. The fastener extends between first and second ends. The slider is slidably mounted to the fastener for movement between the first and second ends. The injection-molded end stop is located at at least one of the first and second ends. The end stop terminates the movement of the slider at the one of the first and second ends. The end stop includes interior plastic material disposed in an interior of the fastener between the first and second profiles. The one of the first and second ends includes a cut edge at an angle relative to an axis of the fastener extending between the first and second ends. The end stop may include exterior plastic material along an exterior of the fastener outside the first and second profiles and covering the cut edge. A method of forming the end stop is also disclosed.

    Abstract: Packages with active agents are described. Generally, the disclosed packages have a pair of opposing body panels joined together along a pair of opposing sides and a bottom bridging the sides so as to define a mouth opposite the bottom, a reclosable fastener extending along the mouth, and an active agent. The reclosable fastener includes a pair of polymeric tracks, in which each of the tracks includes a mating element and a fin portion. The mating elements are releasably engageable to each other, and each of the fin portions extends downwards from the respective mating element towards the bottom of the reclosable package. The active agent is associated with at least one of the fin portions for communication with the interior of the reclosable package.

    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: 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. The preseals are advantageous in that they allow the fastener to be controlled during such downstream operations as notch formation and slider installation and when the fastener is tensioned by various rollers in the bag making machine. The preseals keep the interlocked profiles together and prevent them from moving longitudinally relative to each other. In addition, the preseals generally encompass the respective notches to assist in providing a leakproof barrier to entry into an interior of the fastener between the fins via the notches. This leakproof barrier is effective in the ultimately formed plastic bags.

    Abstract translation: 滑块操作的紧固件包括第一和第二相对的轨道，包括相应的第一和第二互锁轮廓以及从相应的第一和第二轮廓向下延伸的相应的第一和第二翼片。 第一和第二散热片通过多个间隔的预压件彼此密封。 在产生每个预制件之后，在所产生的预制件的翅片的型材和上部形成切口。 为了将滑块安装到紧固件上，滑块首先被定位在相应的凹口内，然后响应于滑块和紧固件的相对运动而被拧到紧固件上。 在形成每个预制件和相应的切口的步骤之前或之后，并且安装相应的滑块，紧固件被附接到移动的塑料薄膜。 随后将紧固件承载网折叠并密封以形成单个塑料袋。 预制件的优点在于，它们允许在诸如凹口形成和滑块安装的下游操作期间以及当制袋机中的各种辊紧固紧固件时控制紧固件。 预制件将互锁型材保持在一起，并防止它们相对于彼此纵向移动。 此外，预压件通常包括相应的凹口以帮助提供防漏屏障，以经由凹口进入翅片之间的紧固件内部。 这种防漏屏障在最终形成的塑料袋中是有效的。
