13 gallon compostable trash bags are one of the most widely used sizes in the US market, especially for kitchen waste, food scraps, and retail applications.
However, not all 13 gallon bags perform the same. Differences in thickness, material composition, and certification can significantly affect durability, leakage resistance, and compliance with local waste systems.
This guide explains how to choose the right 13 gallon compostable trash bags for your business, whether you are a distributor, importer, or private label brand.
What Are 13 Gallon Compostable Trash Bags?
13 gallon compostable trash bags are designed to fit standard kitchen trash bins in the United States (typically 49–50 liters).
Unlike conventional plastic bags, certified compostable versions are made from biodegradable materials such as PLA and PBAT, allowing them to break down under composting conditions.

What Thickness Should You Choose?
Thickness is one of the most important factors affecting performance.
Typical thickness range:
- 12–15 microns → light kitchen waste

- 20+ microns → heavy or wet waste
Key considerations:
- Too thin → risk of tearing or leakage
- Too thick → unnecessary cost increase
