The best storage is in painting racks, separated from touching other paintings.The tops of the paintings can be covered to keep out dust. This allows for good ventilation to prevent mold growth. Paintings can also be stacked vertically with acid free cardboard separators. If paintings must be covered, use acid free tissue, followed by plastic film. Do not wrap tightly as to seal in moisture. Do not use bubble wrap as the bubbles can imprint into the canvas. Maintain mild temperature and low humidity levels. High and freezing temperatures can adversely effect the painting and painting/plastic interaction.
