I store my film, in the canister, in the cardboard box, about 10 boxes per large (1 gal?) plastic ziplock bags, the freezer. I started stocking up when/where ever I could about 3 years ago. I currently have about 200 rolls of Fuji & Kodak, 100, 200, 400 in the deepfreeze at -5 degrees F. Most of it expires in 2023 & 2024. It will be fine, frozen.
