What makes Ziploc freezer bags better at keeping frozen food fresh?

  • Its “open design” keeps food out of the zipper while filling for a mess-free seal.
  • One-click closure (ie a secure and locked zipper)
  • Correct sizing
  • Strong side seams
  • Double zipper strength (ie two sealing lines prevent tearing)

Can I Reuse Freezer Ziploc Bags?

Yes! ZIPloc says its bags are “made from high-quality materials that are strong enough to be used over and over again” — which means the bags are safe to reuse multiple times.

The brand cautions against reusing bags that contain raw meat, fish, eggs, or any other potentially allergenic foods. That sounds like a smart and safe choice to me! Before reuse, bags should be hand washed with warm soapy water, rinsed thoroughly, and left to air dry.
