A shopping bag is a container used to carry purchased items from a store. It can be made from various materials, including paper, plastic, or fabric. Shopping bags come in different sizes and designs, often featuring handles for easy transport. They are commonly used in retail environments, such as grocery stores and boutiques. Many stores offer reusable shopping bags to promote sustainability and reduce plastic waste. These bags can be used multiple times, making them an eco-friendly alternative to single-use plastic bags. Some shoppers also prefer to bring their own bags, contributing to environmental conservation efforts and reducing their carbon footprint.
