Black garbage bags are opaque bags primarily used for general waste disposal, offering concealment and privacy for discarded items. They are commonly made from polyethylene, such as linear low-density polyethylene (LLDPE) or low-density polyethylene (LDPE), which provides tear and puncture resistance. These bags are available in various capacities and thicknesses to suit different uses, from light household waste to heavy-duty industrial refuse. Some black garbage bags are designed to be degradable or recyclable.
