Reusable shopping bag

A reusable shopping bag, sometimes called a bag for life in the UK,^[1][2] is a type of shopping bag which can be reused many times, in contrast to single-use paper or plastic shopping bags. It is often a tote bag made from fabric such as canvas, natural fibres such as jute, woven synthetic fibers, or a thick plastic that is more durable than disposable plastic bags, allowing multiple use. Other shoppers may use a string bag or a wheeled trolley bag. They are often sold in supermarkets and apparel shops.

Reusable bags require more energy to produce than common plastic shopping bags. One reusable bag requires the same amount of energy as an estimated 28 traditional plastic shopping bags or eight paper bags. A study commissioned by the United Kingdom Environment Agency in 2005 found that the average cotton bag is used only 51 times before being thrown away.^[3] In some cases, reusable bags need to be used over 100 times before they are better for the environment than single-use plastic bags.^[4]
