A reusable bag is a durable bag designed for multiple uses, often made from materials like cotton, jute, or recycled plastic. These bags are commonly used for shopping, helping to reduce the reliance on single-use plastic bags, which contribute to environmental pollution. Many stores encourage customers to bring their own reusable bags to promote sustainability. Reusable bags come in various sizes and styles, making them suitable for different purposes, such as grocery shopping or carrying personal items. Some are foldable for easy storage, while others may have additional features like insulation for keeping food items fresh. Using a reusable bag is a simple way to support eco-friendly practices.
