My mother always re-wrapped meats and chicken before freezing it. Is that necessary?
That's a whole lot of work you needn't bother with. You can freeze meat and poultry right in the original packaging, although it is not air tight. If you use the meat or poultry fairly quickly, the quality won't be noticeably affected by the fact that the package isn't airtight. To keep your purchase in top quality for longer freezer storage, wrap right over the original packaging with plastic wrap or foil. When freezing food, the goal is always to prevent it from contact with air as much as possible.
