Bacon is awesome. Wasting bacon is not awesome. So don't pop your bacon straight into the freezer. The Kitchn has an easy trick to individually freeze slices for easy thawing without any waste.
All you will need is some wax paper or baking paper. You stack your slices individually while folding the wax paper above each slice. Basically, you will form an accordion with the bacon and wax paper layers.
Once you're done, pop this into a freezer bag and place it into your freezer. When you need to use bacon, you just tear off as many slices as you need. They separate easily, unlike a whole pack of slices frozen together. Then it's just a matter of thawing the slices and they will be good to go.
