Shield N Seal's Clear and Black 5" x 8" Vacuum Sealer Bags are perfect for small storage, travel, and organization. Our thick BPA free zipper bags safely store food, or can help you organize office supplies, survival gear, daily medications, or even computer cables. And while it locks in flavor, it will also lock in odor. You don't have to worry about strong smells emanating from a Shield N Seal bag. Pungent food or garden odors are locked in tight, for good. These bags have a unique double seal feature. You can vacuum seal your bag, and then use our zipper closure to open and close your bag over and over again. These bags enable you to decided between long and short term storage while maintaining the highest quality and integrity available on the market. The clear plastic is perfect so you can see the contents of your bag, and has white areas that make it easy to label. You'll be able to easily find what you're looking for as you pull it out of storage. Don't forget to reuse your bags! Just trim off the rough edge, and reseal. It's simple to save money by not only saving money on food, but also on the bags themselves. Our bags feature a honeycomb channel system that makes them compatible with most sealers that are 8" or wider. We recommend using our Sealers for the strongest, thickest seal, but our bags can be used with a variety of systems. One side of bag has a zipper closure that is pre-sealed. The other side is fully open and can be heat sealed once the bag is filled. We recommend Shield N Seal Sealers for optimum heat seal closure, but these bags work with most heat sealing devices.
