Garbage bag is a disposable bag used to contain trash or garbage. Such 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 these days are made out of plastic, and are typically black in color.Plastic bags are a convenient and sanitary way of handling garbage, and are widely used. Plastic garbage bags are fairly lightweight and are particularly useful for messy or wet rubbish, as is commonly the case with food waste, and are also useful for wrapping up garbage to minimize odour. Plastic bags are often used for lining litter or waste containers or bins. This serves to keep 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.
