FDA compliance means following hygiene standards in the U.S. for safe production, labeling, and importation of food and agricultural products. Wall panels need to have these important features: 1. Non-Porous Surface: They should not soak up liquids or food particles. This helps prevent moisture buildup and mold growth. 2. Seamless Design: Interlocking panels create a smooth surface with no cracks. This reduces dust and debris and makes cleaning easier. 3. Chemical Resistance: They must resist damage from strong chemicals and disinfectants without breaking down. 4. Safe Materials: The materials must not leak harmful substances gases. They should also withstand impacts without shedding particles. These features help ensure that wall panels meet FDA hygiene standards.
