Reusable shopping bags are a kind of carrier bags, which are available for sale in supermarkets and apparel shops. Reusable shopping 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.
An unpublished report from the UK's Environment Agency found that when compared to a traditional plastic bag, a canvas or cotton reusable bag would have to be reused a total of 171 times to offset the higher carbon emissions. The same study found however that the average cotton bag is used only 51 times before being thrown away.

es on distribution of disposable plastic bags or to regulate the use of them. Supermarkets increasingly discourage consumers from using disposable plastic bags and offer alternative reusable shopping bags with small prices, providing information on environmental damage associated with plastic bags. Because of these encouragements, reusable shopping bags are gradually taking place beside plastic bags. The shape of reusable shopping bags which are now becoming popular is usually different from what they used to be before the prevalence of plastic bags.

s encourage the use of reusable shopping bags to increase sales and profit margins. Most non woven polypropylene bags cost $0.10-0.25 to produce and are sold for $0.99-$3.00 in most cases. As stores receive diminishing returns due to saturated markets, there are concerns that prices will drop and they will become the new single use bag. Some major supermarket chains have string or calico bags available for sale. They are sold with announcement of environmental issues in many cases. The ones sold in supermarkets often have designs related to nature, such as prints of trees or that of the earth, in order to emphasize environmental issues. Some supermarkets give points for customers when they bring own shopping bags. When the customers collect a certain amount of points, they can usually get discount coupons or gifts, which motivate customers to reduce plastic bag use. Some retailers such as Whole Foods Market

s. In the UK, these are sold for a nominal sum, usually 10 pence, and are replaced for free. The bags are more durable than standard bags, ensuring that they may be reused many times.

The main purpose of this is to ensure that the bags are recycled (which usually earns the retailer a small amount of money per bag), and unlike with free carrier bags there is a (small) financial incentive to bring the bags back for recycling, lessening the environmental impact.

In contrast to more spartan carrier bags, bags for life tend to be colourful and show some aspect of the supermarket's advertising. Some supermarkets maintain the same design for years at a time, whereas some, like Waitrose

' was the first supermarket to use them. As of April 2008, Marks and Spencer are giving their Bags for life free to every customer, as their normal plastic bags will have to be paid for from May 6. This will be a small sum of 5 pence a carrier. The bags are given to the customer every time they shop so they will have plenty when the switchover in May comes live.

Apollo Bags was the first company in the United Kingdom to introduce the popular shopping bag with a rubber-based biodegrable lining which will degrade within our lifetime.

Increasingly the use of Jute and Juco bags has provided a natural alternative to single use plastic bags and reusable plastic bags. Over 25 million have been sold in the UK. Reusable plastic bags do not have a simple end of life disposal route. Many are made of mixed plastics so they cannot be easily recycled or are so highly coloured the only reuse is black bin bags which are energy intensive to convert.

Jute bags have become a crossover product from an alternative to plastics to a fashion / shopper accessory. Jute bags will last for about 4 years - if used correctly will replace over 600 single bags. At end of life they can be used as planters for growing garden vegetables.

Research

The accelerating volume of reusable bags being imported and resold, along with the 2008 Wall Street Journal article, An Inconvenient Bag, that documented that only 10% of bags are actually being reused raise statistical questions about their effectiveness and the possibility that these heavier bags have become the new disposable bag. The 2004-2008 Chinese import numbers were enough sell or give away to each family of four in America with more than 21.2 bags over the just the past five years.

, that reported the total annual retail carrier bag consumption is the United States at 97 billion bags annually, the 504 million bags imported from China in 2008 offset just 9.7 billion retail carrier bags (10% of total as reported by the Wall Street Journal) which translated to each reusable bag on average only offset just 19.5 retail carrier bags during its lifespan. Although reusable bags are capable of offsetting more, it is likely that due to lack of use, increased free distribution of these heavier bags, commercialization and commoditization that they are becoming a disposable product with a limited lifespan.

On 23 October 2009 Walmart abandoned plans to remove carrier bags but they continued to introduce the new lower cost bags. In contrast to previous bags sold at $0.99 and $0.50 these lower cost bags may reduce price incentive to reuse these heavy bags.

 Ministry of Health. Because of their repeated exposure to raw meats and vegetable there is an increased risk of foodborne illness. A 2008 study of bags, sponsored by the Environmental and Plastics Industry Council of Canada, found mold and bacterial levels in one reusable bag to be 300% greater than the levels that would be considered safe in drinking water.
The study does not differentiate between non-hemp bags and hemp bags, which have natural antimildew and antimicrobial properties.

A 2010 joint University of Arizona and Limo Loma University study (sponsored by the American Chemistry Council, a trade group that advocates on behalf of disposable plastic bag manufacturers) the found that "Reusable grocery bags can be a breeding ground for dangerous foodborne bacteria and pose a serious risk to public health". The study found that 97% of users did not wash them and that greater than 50% of the 84 bags contained coliform (a bacteria found in fecal material), while E. coli was found in 12% of the bags. The study made the following recommendations:
  1. States should consider requiring printed instructions on reusable bags indicating they need to cleaned or bleached between uses.
  2. State and local governments should invest in a public education campaign to alert the public about risk and prevention.
  3. When using reusable bags, consumers should be careful to separate raw foods from other food products.
  4. Consumers should not use reusable food bags for other purposes such as carrying books or gym clothes.
  5. Consumers should not store meat or produce in the trunks of their cars because the higher temperature promotes growth of bacteria, which can contaminate reusable bags.


The study further showed that machine or hand washing even without the presence of bleach was effective in reducing coliform and other bacteria in the bags to levels below detection.

, in September 2010, "Wegmans Food Markets Inc., owner of a chain of East Coast supermarkets, announced it would replace reusable shopping bags after a consumer group found the sacks had high levels of lead." Bloomberg News also stated that the high levels were related to two specific designs, totaling more than 725,000 bags.

After a report in the Tampa Tribune in November 2010 that elevated levels of lead were found in similar reusable bags, the Food and Drug Administration opened an investigation responding to calls by U.S. environmental and consumer groups, as well as U.S. Senator Charles Schumer, to investigate the reusable bags commonly distributed by grocery stores and large retail chains.

Sears' Canadian stores announced a recall on reusable bags because of similar findings on January 6, 2011.

Other concerns have been raised about the safety of reusable bags due to infrequent washing and the presence of bacteria but these have mostly been discounted.
