A plastic film bag includes a reclosable closure which is opened and closed by a slider. The bag includes a tamper evident sheet closing off the bag mouth. Alternatively the tamper evident means consists of a hood which encloses the slider and reclosable closure.

Tamper evident zipper slider

A slider zipper reclosable fastener wherein the zipper includes fastener strips and closure elements on the fastener strips which are extruded integrally. The closure elements are arranged at particular angles by extrusion opening angles in order to increase burst strength. Ridges on the fastener strips and shoulders on the slider hold the slider on the zipper.

Slider zipper reclosable fastener

A slider zipper reclosable fastener wherein the zipper includes fastener strips and closure elements on the fastener strips which are extruede integrally. The closure elements are arranged at particulare angles by extrusion opeining angles in order to increase burst strength. Ridges on the fastener strips and shoulders on the slider hold the slider on the zipper.

Slider zipper recloseable fastener

In a thermoplastic bag having a reclosable fastener extending along the mouth of the bag and a slider straddling the fastener for opening and closing the fastener, the fastener including two opposing interlocking profiles along the side walls of the bag, the slider adapted to maintain straddling relation with the fastener, an improved endstop means proximate to at least one end of the reclosable fastener, the endstop means being formed from the material of the profiles and rising vertically from the fastener to a height adequate to engage the slider and prevent movement of the slider past the end of the bag. A rail extends along the length of at least one of the profiles on the outside thereof, the rail extending to a point sufficient to permit the slider to cooperate with the rail to maintain straddling relation with the fastener when the slider reaches the endstop. Docking means and methods of making endstop means and docking means are also disclosed.

Endstop and docking means for thermoplastic bags

A security bag having attached thereto an auxiliary bag with a reclosable zipper. The security bag is sealable by a flap having hot melt adhesive thereon. Tamper evidence is provided by a permanent color change of a colored marking adjacent the flap. The color change results from the application of extreme cold temperature to the flap.
