Abstract: Reclosable bags having a slider-actuated string zipper and a tamper-evident feature. In one aspect, the reclosable bag comprises: a receptacle having a mouth and an interior volume; a string zipper installed in the mouth; a slider mounted to the string zipper; and a tamper-evident feature that blocks access to all or a portion of said interior volume. The tamper-evident feature may take the form of an internal membrane that partitions the interior volume or an external header that covers the string zipper. In some embodiments with a partitioned interior volume, the tamper-evident feature comprises a peel seal.

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.

Abstract: A bag having a tamper evident closure and methods of forming the same are provided. The bag has a tube body with a front wall and a back wall positioned between a first end and a second end. A back flap extension member connects to and extends outwardly from the second end of the back wall. A primer material is positioned on the back flap extension member and an adhesive material is placed on the back flap extension member that folds over to overlie and contact the primer material. The back flap extension member adheres to the front flap extension member and portions of the front wall to close the second end. When the back flap extension member liftingly separates from the front wall, at least one of the back flap extension member and the front wall tears indicating evidence of tampering.
