Ameripak offers different types of slide-seal poly bags for the storage and protection of everyday use items. These bags are designed with track zippers, which help provide a strong seal. The track zipper also prevents any dirt and dust from entering the bag. The bags are also puncture resistant, which makes them the perfect poly bag type to hold and store sharp or heavy components. Ameripak also provides white block slide-seal poly bags with write-on panels. This allows the user to write important information about the product on the panel.
