A garbage bag is a utilitarian, flexible container typically made from plastic, used for the containment and disposal of waste materials. They are designed to be strong and tear-resistant to handle various types of waste without leaking or tearing easily. Garbage bags are available in different sizes and thicknesses to accommodate different types and volumes of waste, ranging from small kitchen bins to large industrial bins.

Common features of garbage bags include:

1. Material: Most garbage bags are made from polyethylene (PE) plastic, which is durable and flexible. High-density polyethylene (HDPE) and low-density polyethylene (LDPE) are commonly used materials.

2. Closure: Many garbage bags have drawstrings, ties, or flaps at the opening to securely close and tie off the bag once it is full. This helps to prevent spills and contain odors.

3. Capacity: Garbage bags come in various capacities measured in liters or gallons, indicating how much waste they can hold. This ensures they can fit appropriately into different sizes of waste bins.

4. Color: While traditionally black, garbage bags now come in a variety of colors for different purposes, such as green for compostable waste or clear for recycling.

5. Strength: Garbage bags are designed to withstand the weight and sharp edges of typical household or commercial waste without tearing. Reinforced seams and thicker plastic are often used for heavy-duty bags.

Garbage bags play a crucial role in maintaining cleanliness and hygiene in homes, offices, and public spaces by facilitating the easy collection, containment, and disposal of waste materials.
