Milk storage!

C
How do you mamas store your pumped milk in the freezer? We have been using a 12-pack can box to organize in our deep freezer (googled example below) but we are officially out of room. 
Is there a better way?? I don't want to just stick the bags in there without some sort of protection because I'm afraid the bags will get stuck to the sides and tear. I produce 2-3 times more milk than baby needs so I've filled the freezer fast. Baby is only 10 weeks old and I don't want to stop pumping just because I'm out of storage room. Needing those suggestions!! We only have room for 2 more boxes.
