A bin bag, rubbish bag (

American English) or refuse sack is a disposable bag used to contain solid waste. Many bags are useful to line the insides of waste containers to prevent the insides of the receptacle from becoming coated in waste material. Most bags today are made out of plastic, and are typically black, white, or green in color.[1]

food waste
, and are also useful for wrapping up garbage to minimize odor. Plastic bags are often used for lining litter or waste containers or bins. This keeps the container sanitary by avoiding container contact with the garbage. After the bag in the container is filled with litter, the bag can be pulled out by its edges, closed, and tied with minimal contact with the waste matter.

Garbage bags were invented by Canadians Harry Wasylyk, Larry Hansen and Frank Plomp in 1950.[2] In a special on CBC Television, green garbage bags (first bin bags in Canada) ranked 36th among the top 50 Canadian inventions.[3] Black plastic bags were introduced in 1950 as star sealed bags. The first bags in the United States were green and black, rather than the now-common white and clear. Flat-sealed bags first appeared in 1959. In the 1960s, the white bin bags were introduced. Two-ply (Heavy Duty) bags were introduced in 1974, with 3 ply bags following in 1980.

Plastic bags can be incinerated with their contents in appropriate facilities for waste-to-energy conversion. They are stable and benign in sanitary landfills; some are degradable under specified conditions.[citation needed]

Biodegradable plastic bags

Oxo-biodegradable plastic bags have the same strength as ordinary plastic and costly slightly more. They will degrade then biodegrade if they get into the open environment, but they can be recycled if collected during their useful life. They are designed so that they will not degrade deep in landfills and will not, therefore, generate methane. Oxo-biodegradable plastic does not degrade quickly in low temperature "windrow" composting, but it is suitable for "in-vessel" composting at the higher temperatures required by the animal by-products regulations. Oxo-biodegradable plastic is bio-assimilated by the same bacteria and fungi, which transform natural material such as twigs and leaves to cell biomass, like lignocellulosic materials. Oxo-biodegradable plastic is designed to degrade initially by a process that includes both photo-oxidation and thermo-oxidation, so it can degrade in the dark. Resin identification code
7 is applicable to biodegradable plastics.

Drawstring and flexibility

In 1984, drawstring garbage bags first appeared before GLAD[4] and Hefty[5] introduced them. In August 2001, Hefty introduced the garbage bags with a drawstring designed to stretch around the garbage can's rim and stay in place.[6] In July 2004, ForceFlex, the flexible plastic garbage bags, was introduced by GLAD[4] (followed by Hefty's Ultra Flex brand in September).[7]
