To store acrylic sheets properly, follow these guidelines: 1. Store in a cool, dry place: Acrylic sheets are sensitive to heat and moisture. Store them in a cool and dry environment to prevent warping or distortion. 2. Avoid direct sunlight: Prolonged exposure to sunlight can cause acrylic sheets to yellow or become brittle. Store them away from windows or other sources of direct sunlight. 3. Store vertically or with support: Ideally, acrylic sheets should be stored vertically, such as leaning against a wall or in a vertical rack. If stored horizontally, make sure there is sufficient support along the length of the sheet to prevent bending or sagging. 4. Protect the surfaces: Place a protective layer, such as foam or a soft cloth, between each sheet to prevent scratching or damage. Avoid using materials that may react with the acrylic, such as rubber or adhesive tape.
