I find that almost anything in my freezer gets ice in it, and often has freezer burn after about a month. The freezer itself is free of ice.

This includes microwave dinners that come pre-sealed from the factory. They will develop a significant amount ice inside in about a month.

Is there some way to prevent this, perhaps something I could put in the freezer?

Freezer burn is caused by sublimation. If it happens, it suggests that the food packaging isn't airtight.


It is possible to slow freezer burn by filling plastic containers with water and leaving them open (leaving room for expansion) in the freezer to help maintain humidity.
