Why does everything in my freezer have freezer burn?
Common culprits that lead to freezer burn include improper packaging or temperature, as well as too much time spent in the freezer. Cold, dry air is more likely to permeate foods that aren’t tightly wrapped, left open or stored in frequently fluctuating temperatures, which can cause drying.
To help protect the look, taste and texture of your food, be sure to properly package items and set the freezer temperature correctly. You can also help keep frozen food fresh longer by avoiding long storage times.
