Many citizens use plastic bags as garbage bags, but many countries and regions have banned or restricted the use of plastic bags. The San Francisco City Council passed a bill prohibiting retailers such as supermarkets and pharmacies from using plastic bags. In cities such as Los Angeles, the government has launched plastic bag recycling campaigns. Some places in countries such as Canada, Australia, and Brazil have also introduced regulations prohibiting plastic shopping bags or paid use.

Garbage bag, as the name suggests, is a bag for storing garbage. A small bag brings considerable convenience to thousands of households and provides important protection for the environment, even facilitating garbage recycling and classification.
