Thermal bags are insulated containers designed to maintain the temperature of their contents, whether hot or cold. They are commonly used for transporting food and beverages, ensuring that meals stay warm or drinks remain chilled during travel. The insulation material helps to minimize heat transfer, making them ideal for picnics, catering, or daily meal prep. These bags come in various sizes and styles, often featuring handles or straps for easy carrying. Many thermal bags are made from durable, easy-to-clean materials, making them practical for repeated use. They are popular among families, outdoor enthusiasts, and anyone needing to transport temperature-sensitive items.
