A paper tray is a flat, shallow container designed to hold sheets of paper, documents, or other flat items. It is commonly used in offices, schools, and homes to organize and store papers, making it easier to access important documents. Paper trays can be made from various materials, including plastic, metal, or cardboard, and come in different sizes and styles. These trays often feature a stackable design, allowing multiple trays to be stacked on top of each other to save space. Some paper trays may also have compartments or dividers for better organization. They are essential tools for maintaining a tidy workspace and improving productivity.
