Shopping bags are medium-sized bags, typically around 10–20 litres (2.5–5 gallons) in volume (though much larger versions exist, especially for non-grocery shopping), that are often used by grocery shoppers to carry home their purchases. They can be single-use (disposable), used for other purposes (storage, can liners, etc.) or designed as reusable shopping bags.

Types

Types and typical use of shopping bags vary by country:

• In many European Union countries, plastic shopping bags are free and common into the 21st century, but their use is becoming less widespread, partly due to environmental legislation, which has led retailers to charge for single-use plastic shopping bags^{[citation needed]}. Ireland, for example, imposed a dedicated plastic bag tax, thus forcing retailers offering plastic bags to charge for them.^[1]
• Reusable shopping bags are increasingly used, e.g. in E.U. countries where use of single-use plastic shopping bags is in decline. Reusable bags are often made from jute cloth, also known as burlap in the U.S., but sometimes they are also made from plastic; however these reusable plastic bags are sturdier than single-use plastic shopping bags. In the U.S., reusable bags are used as a fashion statement or for advertising.^[2]
• In the United States and Canada, single-use plastic shopping bags are common and often free with a purchase. Some retailers, such as department stores, are more likely to provide paper bags to shoppers, whereas supermarkets and grocery stores tend to favour plastic shopping bags. People are encouraged to have reusable shopping bags, whenever possible, and in some municipalities, they must pay a government-mandated fee if they wish to utilize plastic shopping bags.

In an effort to reduce plastic bag use, the city of Toronto requires retailers to charge a minimum CA$0.05 fee for each plastic bag; prompted by the plastic bag charge in Toronto, many national retailers have imposed similar fees on plastic bags in their outlets in other parts of Canada. All of the profits derived from the $0.05 fee go directly to the retailer.^[3][4]
