It really depends on the quality of the bread and the loaf packaging. Bread and bread packaging differs greatly across the world. The lighter the bread, the more likely it is too dry out quickly. The packaging needs to prevent it from freezer burn, a high quality bread bag does more then a piece of plastic that’s supposed to let the bread air out.

Give it a try, buy a heavier bread and stick it in a good plastic bag. Should last a week easily. Make sure your bread is pre cut as cutting frozen bread is not fun.
