Shelf Life Tips

  • How long does an opened package of potato chips last? The precise answer depends to a large extent on storage conditions - store in cool, dry area.
  • How long do opened potato chips last at room temperature? Properly stored, an opened package of potato chips will generally stay at best quality for about 1 to 2 weeks at room temperature.
  • To maximize the shelf life of opened potato chips, keep package tightly closed.
  • Are opened potato chips safe to use after the "expiration" date on the package? Yes, provided they are properly stored and the package is undamaged - commercially packaged potato chips will typically carry a " Best By," "Best if Used By," "Best Before", or "Best When Used By" date but this is not a safety date, it is the manufacturer's estimate of how long the potato chips will remain at peak quality.
  • Storage time shown is for best quality only - after that, the potato chips' texture, color or flavor may change, but in most cases, they will still be safe to consume if they have been stored properly, the package is undamaged, and there are no signs of spoilage (see below).
  • How can you tell if potato chips are bad or spoiled? The best way is to smell and look at the potato chips: if potato chips develop an off odor, flavor or appearance, or if mold appears, they should be discarded.
