Custom compostable poly bags are becoming a top choice for brands looking to reduce plastic use and support sustainable packaging. But one of the most common questions buyers ask is: How much do custom compostable bags really cost?

Let’s break it down simply, and explore what affects the price—and how you can get the best value.

🌱 What Are Compostable Poly Bags?

Compostable poly bags are made from plant-based materials like PLA (polylactic acid) and PBAT, which decompose into natural elements under composting conditions. Unlike traditional plastic bags, compostable bags leave no microplastics behind.

These bags can be used for packaging clothing, skincare, supplements, mailers, trash bags, and more. Many brands now request custom compostable bags with their logo, brand color, and size specifications.

💰 What Affects the Cost of Custom Compostable Bags?

The cost of custom compostable bags varies depending on several factors:

1. Bag Size and Thickness

Larger or thicker bags use more material, which increases the price. For example:

• Small flat bags (15x20cm) may cost around $0.05–$0.08 per piece.
• Large mailer bags (35x45cm) may cost $0.15–$0.25 per piece, depending on material and features.

2. Material Type

• PLA + PBAT blends are commonly used. They offer strength and good compostability.
• 100% PLA or starch-based bags might cost more due to material purity.

3. Print and Customization

• Single-color printing is cheaper than multi-color.
• Adding features like ziplock, drawstrings, or perforation increases costs.

4. Order Quantity

Larger orders bring lower unit prices. A batch of 50,000 bags can be 20–40% cheaper per piece than an order of 5,000.

5. Compostability Certifications

If your bags need certifications like OK Compost HOME, BPI, or EN 13432, the production may include additional testing costs.

4. What certifications should I look for in compostable bags?

• OK Compost HOME
• BPI (US Biodegradable Products Institute)
• EN 13432 (Europe) These ensure the bags truly decompose under composting conditions.

5. What is the difference between home compostable and industrial compostable bags?
