Tea bags are small, porous bags designed to hold tea leaves and allow for steeping in hot water. They are commonly made from materials like paper, silk, or nylon, which allow the flavor and aroma of the tea to infuse into the water while keeping the tea leaves contained. Tea bags are popular for their convenience, as they eliminate the need for tea strainers and make it easier to brew a single cup or pot of tea. Many tea bags are now designed to be more eco-friendly, using biodegradable materials and reducing the overall environmental impact of packaging. In addition, tea bags often come in a variety of shapes and sizes, such as traditional square or rectangular shapes, pyramid shapes for more room for the leaves, and even sachets for luxury teas. Their compact packaging allows for easy storage, and the inclusion of strings or tags makes them user-friendly and easy to handle.
