Abstract: A method and apparatus for securing a zipper closure to polymeric film using minimal tension on the zipper closure includes providing first and second tension control loops, an eyemark detector, and a hole punch programmed to punch a hole in the zipper closure upon detection of the eyemark. The zipper closure and the film are supplied to a sealing station at the same speed, and the hole zipper closure is aligned with the eyemark on the film, to result in sealing the strip of zipper closure to the film resulting in minimal wrinkles to the resulting bag.

Abstract: A child resistant zipper closure for a bag includes a slider having a flexible tab with a torpedo. To open a zipper closure, the tab must be held in a downward position to engage the torpedo between male and female tracks and result in separation of interlocked complementary profiles, while the slider is moved along the zipper closure.
