Keeping your 8mm film cool and dry will help you preserve it for a long time. Don't let the light of day ruin your film. Please keep it safe in a cool place with no sunlight to fade and warp it. Store 8mm films away from any windows. Don't keep it inside plastic bags or sealed containers if you want your film to last as long and look its best. The film naturally degrades over time, so the gases need to escape from within the container. If you want to store your film for a long time, remove any materials that could be attached and keep it alone. Ensure there are no tapes or anything else on the reel itself. These might cause further damage by introducing outside chemicals into what is already an aging process inside those old films. If you label 8mm film, you should attach the label outside the container box and use acid-free paper. Don't put storage labels on the film.
