As a manufacturer and sustainability advocate, I’m aware of the growing demand for eco-friendly packaging solutions, especially biodegradable plastic bags. As more businesses and individuals turn to green alternatives, many are curious: How much do biodegradable plastic bags really cost?
In this guide, I’ll walk you through what I know about biodegradable plastic bag pricing, from the factors that affect cost to how to reduce costs when buying in bulk or customizing. I hope it helps.
What Are Biodegradable Plastic Bags?
Biodegradable plastic bags are made from materials that break down naturally over time, usually through microbial activity. The most common materials include PLA (polylactic acid), PBAT (polybutylene adipate terephthalate), and cornstarch-based blends. Unlike traditional polyethylene bags, these green alternatives decompose into non-toxic components.
In my factory, we often produce bags that meet global standards like ASTM D6400, EN13432, and BPI certification. Some clients refer to these as eco plastic bags, compostable plastic bags, or plant-based plastic bags. While “biodegradable” and “compostable” are sometimes used interchangeably, compostable bags are designed to break down under specific composting conditions and leave no toxic residue.
What Factors Affect the Cost of Biodegradable Plastic Bags?
From my experience supplying to wholesalers, Amazon sellers, and retail chains, I’ve seen several key factors that determine biodegradable plastic bag costs:
1. Raw Materials
- PLA and PBAT are more expensive than traditional plastic resins.
- Cornstarch-based blends are sustainable but add to the price.
- Certifications like BPI certified or EN13432 often mean higher material quality and increased cost.
2. Bag Size and Thickness
- Larger or thicker bags require more material.
- Custom shapes or high-load-bearing designs (e.g., garbage bags, shopping bags) add to the price.
3. Printing and Customization
- Custom printed biodegradable bags with logos or QR codes increase unit price.
- Full-color flexographic printing is more expensive than monochrome.
4. Order Quantity
- Like all manufacturing, bulk orders significantly lower the per-unit price.
- Wholesale biodegradable bags are ideal for retailers and packaging suppliers.
5. Packaging and Shipping
- Export orders to the US, EU, or Australia incur freight and compliance costs.
- Retail-ready packaging (with barcodes and branding) also increases total cost.
6. Certifications and Compliance
- Bags that are certified compostable (BPI, TÜV Austria) often cost 10–20% more.
- Compliance with bans on single-use plastic adds testing and labeling expenses.

Biodegradable vs Traditional Plastic Bag Costs
I’m often asked to compare costs between eco-friendly plastic bags and traditional polyethylene ones. Here’s a breakdown:
| Type | Cost Per Bag (Bulk) | Notes |
|---|---|---|
| Traditional Plastic Bag | $0.01–$0.02 | Cheap, but banned in many places |
| Biodegradable Bag | $0.04–$0.12 | Higher, but compostable & legal |
While biodegradable bag pricing may seem high, the environmental cost of plastic pollution is far greater. Cities and businesses are now paying to clean up plastic waste, while sustainable packaging offers long-term savings and a positive brand image.
Are Biodegradable Bags Worth the Extra Cost?
In my view—yes, absolutely. Many of our clients, from grocery chains to fashion retailers, report improved customer satisfaction and stronger branding after switching to compostable bags. Here’s why:
- ROI: Higher upfront cost is offset by eco-conscious brand loyalty.
- Legal Compliance: Many cities require compostable packaging.
- Eco Impact: Reduced landfill, microplastics, and carbon footprint.
Let me give you a real example: A supermarket chain in Australia switched to certified compostable shopping bags. While the cost increased by 25%, they gained local government approval, PR coverage, and saw a measurable increase in customer retention.
How to Get the Best Price on Biodegradable Plastic Bags
- Buy Direct from Manufacturer: Cut out middlemen. You’ll get better pricing and faster delivery.
- Order in Bulk: Larger quantities always reduce per-unit cost.
- Simplify Design: Avoid excessive printing, extra thickness, or fancy handles unless necessary.
- Work with OEM Suppliers: Custom biodegradable bags can be cost-effective if you’re sourcing at scale.
- Bundle Orders: Combine dog poop bags, mailers, and grocery bags in one shipment.
FAQ
Why are biodegradable bags more expensive?
Because they use renewable materials and require compliance testing. PLA, PBAT, and cornstarch all cost more than traditional plastic resins.
Are compostable bags cheaper in bulk?
Yes. Bulk orders significantly reduce the unit cost. For example, dog waste bags can drop from $0.12 to $0.06 per bag with orders over 100,000 pieces.
Can I get custom printed biodegradable bags affordably?
Absolutely. If you’re ordering directly from the factory and printing in 1–2 colors, the cost increase is minimal—about $0.01–$0.03 per bag.
Conclusion
The price of biodegradable plastic bags depends on various factors—material, size, print, certification, and quantity. While they do cost more than conventional plastic bags, the benefits in brand value, legal compliance, and environmental impact make them a smart investment.
If you’re a retailer, packaging buyer, or eco-startup founder looking to make the switch, start by requesting quotes from trusted suppliers. Ask for certifications like EN13432, ASTM D6400, or BPI certified. Compare not just pricing, but the value you gain in sustainability and reputation.
