Powder-Proof™ Zipper
Ideal for powders and particulates, Zip-Pak’s Powder-Proof™ zipper features a patented evacuation port technology which eliminates clogged zippers and provides easy, secure resealing. Products such as flour, sugar, and grains can prevent standard press-to-close zippers from being securely resealed, but the innovative Powder-Proof™ zipper is designed with a channel for powder or particulate residue to fall backwards into the package instead of blocking the zipper channels. Made of low-density polyethylene (LDPED), Powder-Proof™ zippers are available in various designs for use on most pouch converting machines, horizontal form fill seal machinery, and vertical form fill seal machinery.
