A dustbin bag, also commonly known as a trash bag, garbage bag, or bin liner, is a disposable bag designed to line the interior of a dustbin or waste receptacle. Typically made from durable materials such as plastic, these bags serve the primary purpose of containing and facilitating the easy disposal of household or commercial waste. Dustbin bags come in various sizes, ranging from small kitchen trash bags to larger bags suitable for outdoor bins. They often feature a drawstring or tie closure to secure the contents and make disposal more convenient. Some dustbin bags are designed to be eco-friendly, biodegradable, or compostable, addressing environmental concerns. The use of dustbin bags helps maintain cleanliness, simplifies waste management, and contributes to overall hygiene in homes, offices, and public spaces.
