Are zip lock bags airtight?

Ziploc bags create a strong, effective seal for short-term storage, keeping air and moisture out well enough to maintain freshness, but they are not truly airtight for long-term preservation because the thin plastic allows slow oxygen migration over time, which can cause freezer burn or stale food, so for long-term storage, vacuum sealing or airtight containers are better. For everyday use, expelling as much air as possible before sealing, especially using methods like the water displacement for sous vide, significantly improves their performance.
