  • Patent number: 6210038
    Abstract: A peelable seal includes two opposing ribbed layers. The ribs are colored so they are visible when the hermetic seal has not yet been activated. When the hermetic seal is activated, the two opposing ribbed layers fuse together. This fusion destroys the ribs and results in one fused layer. The entire resulting layer is then colored. This provides an indication to the manufacturer that the hermetic seal has been achieved and provides an indication to the consumer that the hermetic seal is intact.

  • Patent number: 6131248
    Abstract: A peelable seal includes four layers. The first layer includes first and second alternating ribs. The first ribs comprise a first material, and the second ribs comprise a second material. The first material bonds well with the closure profiles. The second material bonds well with the third and fourth layers. The first material does not bond well with the second material. Thus, the bond strength is lower between the first and second ribs and between the third and fourth ribs than between the first and third ribs and the closure profiles and between the second and fourth ribs and the third and fourth layers. In this process, the strength of the peelable seal is controlled during the extrusion process rather than being subjected to the variations in the manufacturing process. Alternatively, the peelable seal includes six layers. The first and second layers bond well with the closure profiles. The third and fourth layers bond well with the fifth and sixth layers.

  • Patent number: 5749658
    Abstract: A zipper for a recloseable bag provides a heat-settable portion for adhering the zipper to a polymeric bag at a temperature below that known in the art in order to prevent permanently sealing the bag closed inadvertantly. The zipper includes elongated base strips having flange portions for adhering the inner surface of the base strip to the outer surface of a polymeric bag. The base strip is adhered to the polymeric bag by a heat-setting compound coextruded, coated or laminated to the inner surface of the flange. The flange portions may be thinner than other portions of the base strips to permit the flange portions to be fused to the polymeric bag at a lower temperature than previously practiced.
