Yes. Freezer burn happens when frozen food is exposed to air and dries out. A good vacuum seal keeps air off the food, which is the main way to prevent it.
What freezer burn is
Dry, discolored patches where moisture has left the surface. It's a quality problem, not a safety one; trim the patches and cook.
How to prevent it
- Seal tightly, with no air pockets around the food.
- Check seals before freezing; re-seal any that look wrinkled.
- Keep your freezer at 0°F or below.
- Use older bags first.
In testing
Taste of Home found only small pockets of minor freezer burn on chicken sealed in the Avid Armor USV32 after two weeks frozen.
