When you buy a loaf typically it comes in a single use plastic bag that you store it in then throw that bag away. We've been looking for great solutions for bread storage and we have a couple.
The Onya Resuable Bread Bags are made from recycled, BPA Free, plastic bottles. They are double lined and come with a close which helps you carry your bread back from the bakers and helps reduce air circulation which increases the rate at which your bread goes stale. Easily washable and freezer safe.
If you prefer natural we have a wonderful bread bag to store your loaf in which is cotton.
