How to Choose the Right Trash Bag for the Job

Trash bags are common household essentials. Selecting the right type, size, and thickness of trash bags suitable for the waste they will contain can help save costs, prevent leakage that could affect the environment, and make waste management more organized—especially for businesses like restaurants, factories, or large organizations.

Each area produces a different amount of waste, so the size of the trash bag should match the volume of waste and the bin used. Commonly used trash bag sizes include the following:

• 18 x 20 inches – Suitable for 10–15 liter trash bins, typically small bins used in office rooms or hotels.
• 24 x 28 inches – Suitable for 30-liter trash bins. These are medium-sized bins commonly found in households, small restaurants, or standard cafés.
• 26 x 34 inches – Suitable for 50-liter trash bins, often tall bins used in dormitories or offices.
• 30 x 40 inches – Suitable for 80–100 liter trash bins. These are large bins used in areas with high waste volume, such as restaurants, business establishments, or markets.
• 36 x 45 inches – Suitable for 120–150 liter trash bins. These large bins are designed for industrial use or large buildings.

“Thickness” or “Trash Bag Properties” is another important factor to consider when choosing a trash bag. Thickness is commonly measured in microns. For general household use, medium-thickness black trash bags ranging from 15 to 30 microns are popular for everyday waste. A thicker bag is recommended when the trash is heavier and requires greater durability.

As for trash bag properties, they can be assessed by the type of plastic material used. Different types of plastic offer distinct advantages, such as:

• HDPE (High Density Polyethylene) – Thin, lightweight, and inexpensive. Best suited for light waste.
• LDPE (Low Density Polyethylene) – Strong and flexible. Ideal for general household waste or wet waste.
• Recycled Plastic – Eco-friendly and budget-friendly. Suitable for general waste or use in factories.
• Biodegradable Plastic – Naturally decomposable. Commonly used in hotels or environmentally conscious (Green) businesses.

When choosing a trash bag, aside from size and thickness based on the weight of the waste, another important factor to consider is color-coding or sorting by waste type. This helps make waste disposal at the final destination more efficient and environmentally responsible.
