Materials and How They Work
Compostable ziplock bags come from renewable resources. These include corn starch, PLA (polylactic acid), and PBAT (polybutylene adipate-co-terephthalate). These materials break down into natural elements under composting conditions.
In industrial composting facilities, which maintain temperatures around 55–60°C, these bags can decompose within 90–180 days. Home composting may take longer, but the materials still break down effectively over time.
Key Certifications to Look For
When selecting compostable ziplock bags, look for certifications that ensure the product meets composting standards:
- ASTM D6400: U.S. standard for compostability.
- EN 13432: European standard for compostable packaging.
- OK Compost Home: Indicates suitability for home composting environments.
These certifications confirm that the bags will break down without leaving harmful residues.
Why I Switched to Compostable Ziplock Bags
Environmental Impact
Transitioning from traditional plastic bags to compostable alternatives significantly reduces plastic waste. This change supports environmental sustainability and aligns with growing consumer demand for eco-friendly products.
Brand Value and Customer Trust
Customers increasingly prefer brands that prioritize sustainability. By offering certified compostable packaging, I’ve noticed increased customer engagement and loyalty, enhancing my brand’s reputation.
How to Choose the Best Compostable Ziplock Bags
- Check Material Composition: Request detailed information on the materials used, such as the ratios of PLA, PBAT, and starch.
- Verify Certifications: Ensure the bags have valid certifications like ASTM D6400, EN 13432, or OK Compost Home.
- Test Physical Properties: Do simple tests to check durability and compostability. Look for leaks and watch how things break down in a compost bin.
