The Function Of Moisture-Proof Back Sheets

The primary function of moisture-proof back sheets on hanging paintings is to protect them from moisture, preventing mold, deformation, and other issues. When paintings are left in a humid environment for extended periods, they are easily contaminated by organisms such as mold and bacteria, leading to problems such as black spots, cracks, and blistering. Moisture-proof back sheets effectively prevent moisture and mold, preserving the integrity and aesthetic value of the painting.
