Our larger child resistant bag is opaque and made with an ASTM tested, certified zipper. This bag measures 12" x 4" x 9" and comes in a matte silver finish, making this an excellent opaque exit bag. This bag works well for cannabis products, edibles, medicinal herbs, pharmaceuticals, and more. A high barrier and metallized interior restrict the transmission of moisture and control odors. This smell proof bag is 4 mil thick and requires two hands to open. While this bag is easy for adults to manage, small children will find the pouch difficult to open. A pre-printed illustration is provided on the inside flap to instruct users how to open the bag. Heat seal above the zipper for a tamper evident seal. The matte silver finish provides an opaque barrier that conceals your contents.
