    Abstract: A security bag includes a tamper-evident closure which provides a visual indication if the closure is opened. The closure includes an ink layer deposited on one wall of the security bag or on a flexible strip secured to one wall of the security bag, and an adhesive layer in overlying relationship with the ink layer for sealing the bag closed. The ink layer includes a release material deposited in a predetermined pattern, and a layer of a solid ink applied over the release material so that the predetermined pattern of the release material is not visible in the closure. The solid ink layer includes void spaces arranged in a predetermined pattern. Preferably, the pattern of the void spaces is out of registry with the pattern of the release material so that the void spaces and release material overlap to varying degrees in the closure. If the closure is forced open, the solid ink will delaminate from the surface on which it is printed, revealing in the closure the predetermined pattern of the release material.

  • Patent number: 6786640
    Abstract: The reclosable plastic bag is formed by opposing panels of web with four sides sealed. A zipper is sealed within the bag so that a first zipper profile is sealed to a first opposing panel and a second zipper profile is sealed to a second opposing panel. A slider engaging the zipper profiles in a closed position protrudes from an opening in at least one of the opposing panels and may be further secured in place by a label. The slider cannot be moved from the position wherein the zipper profiles are closed to the position wherein the zipper profiles are open prior to the user tearing a perforated or otherwise weakened line across the panels. When this tear is made, it is unmistakable and intuitive evidence that the bag may have been previously opened and depending upon the circumstances, possibly tampered.

    Abstract: A method for making a reclosable bag (56) with gussets (36, 38) in which a zipper profile (16) is attached to bag-making film (10), while leaving side margins (20, 22) of the film. The film (10) is folded as a tube (26). Gusset-forming wheels (34, 35) indent the tube (26) to form the side gussets (36, 38). The side gussets (36, 38) are sealed to the tube (26) and/or the zipper profile (18) with the profile sealed to the tube. The tube (26) is sealed and cross-cut to form the bag (56). In an alternative method, lengths of tubular gusset material (112) are positioned on a lower web (110) of film (101) transverse to a bag-forming direction. A zipper (124) is sealed in the bag-forming direction to the webs (108, 110), and the gusset material (112). The webs (108, 110) and the material (112) are sealed to each other to form an end seal (140) as well as cross-cut and sealed to form the gussets (144, 148) of a reclosable bag (147).

    Abstract: A flexible package is provided with a shrouded slider fastener closure. The slider traverses fastener tracks which extend across the width of the flexible package, including side seals which form the side margins of the package. The film forming the front and real panels of the flexible package extends over and above the fastener tracks and slider, forming an upper shroud portion. A line of weakness is formed in the plastic film below the fastener tracks and a cut line immediately adjacent a side seal of the flexible package intersects the line of weakness so as to propagate a tear opening thereto. The cut line either extends to the side edge of the flexible package or an opening in the form of a tear notch, for example, is located in the side seal to initiate tearing with propagation to the cut line. In this manner, tension relief is provided for the plastic film while allowing the slider to remain substantially enclosed.
