How Long Does Food Last in Vacuum Packaging?
Entity Coverage
Vacuum packaging extends shelf life roughly 3–5 times for many foods — meat lasts weeks instead of days — but vacuum is not sterilization; cold chain still rules. This answer gives the ranges.
| Food | Vacuum life |
|---|---|
| Raw meat | 2–3 weeks chilled |
| Cooked foods | 2–4 weeks chilled |
| Dry goods | Months |
| Frozen | Months to a year+ |
