Resealable closures for use in sealing polymeric packages are provided. The resealable closures include a sealant material that restricts fluid flow into and out of the resealable closure.

Resealable closures, polymeric packages and systems and methods relating thereto

Evacuable, resealable bag

A method of making and filling reclosable packages using a duplex machine includes the steps of providing a zipper profile, package film and a plurality of sliders; feeding the zipper profile; applying the sliders to the zipper profile; coupling the zipper profile to the folded web; sealing two edges of the folded web to form adjacent pouches; filling the pouches; sealing the pouches proximate a third edge thereof; and separating the pouches in order to form individual packages. The method employs a single rotating slider applicator having a programmable servo motor which is programmed in order to synchronize the application of the sliders to the moving zipper profile with the two at a time form, fill, seal and separate packaging operations of the duplex machine. A duplex machine is also disclosed.

Duplex packaging machine

The present invention provides a storage system having a storage device having at least one polymeric sheet sealed along a portion of its' periphery to provide an opening to a storage space; a resealable closure structure adapted to seal the opening to the storage space, the resealable closure structure comprising selectively engaging male and female profiles and a sealing compound comprising liquid silicone and at least one filler in proportions suitable for at least incidental contact to food items contained within the storage space; a vacuum valve assembly disposed on the polymeric sheet; a stand-off structure disposed adjacent to the vacuum valve assembly, wherein the stand-off structure has a series of raised surfaces facing the vacuum valve assembly; a portable vacuum pump assembly structured to engage the vacuum valve assembly; and a liquid separator assembly coupled to the portable vacuum pump assembly.

Method of applying sliders, duplex packaging machine and slider applicator therefor

A flexible, reclosable package includes first and second panel sections defining an interior, and a zipper sealed to each of the first and second panel sections along a top edge thereof. The zipper includes first and second mating profiles, each having an upper flange. A slider device is constructed and arranged for mounting on the zipper and for interlocking the first mating profile with the second mating profile when the slider device is moved in one direction, and disengaging the first mating profile from the second mating profile when the slider device is moved in another opposite direction. A tamper evident seal attaches the upper flanges of the first and second profiles together and extends through a passageway formed through the slider device. With this construction, pulling of the tamper evident seal will separate the seal from the upper and lower flanges and concurrently engage a portion of the slider device to progressively move the slider device across the first and second closure profiles to provide access to the interior of the package.

A method of making packages having a reclosable zipper closure by a vertical form, fill and seal process. The method includes providing a pocket in a film web into which a zipper closure is positioned and attached. The film web is folded and sealed to form side panels and seams, which result in a package. The pocket provides an internal tamper evident-structure for the package. An external tamper evident-structure can be provided between the distal ends of the mating profiles of the zipper closure.

Methods of manufacturing reclosable packages; and packages made thereby

A flexible, reclosable package having a zipper closure and a slider device mounted thereon, the zipper closure and slider device encapsulated within a tamper evident-structure such as a hood. The hood has a top seal region where the walls of the hood are sealed together; the hood walls can be of the same material as the package walls. In one embodiment, each end of the zipper closure includes an area that terminates the slider device travel; this can be a crush area or region. In order to gain access to the interior of the package, the hood is removed by breaching the hood, such as at an area of weakness that is between the slider device and the region where the zipper closure attaches to the package walls.
