The Child Resistant Zipper Bag is designed for products that should not be consumed by children or taken without adult supervision. The bag features a safety mechanism called the Child-Guard track and slider which was developed specifically to meet the Poison Prevention Packaging Act standards. Adults can easily access its contents by following these instructions. To open the bag, just press down on the tab and pull the slider. Close the bag by pushing the slider back. When filled, the bottom of the bag expands to stand on its own.
