Why Choose Our Compostable Bags
Custom Compostable Bags | ASTM D6400 and Home Compostable Flexible Packaging
Compostable bags are the gold standard of sustainable flexible packaging — manufactured from materials that are certified to biodegrade completely within defined timeframes under composting conditions, leaving no microplastic residue, no toxic compounds, and only water, CO2, and biomass as degradation products. Unlike recyclable packaging that requires collection, sorting, and reprocessing infrastructure, compostable packaging enters the organic waste stream directly, returning nutrients to soil through the composting process.
Compostability Standards
- ASTM D6400: US standard — materials must biodegrade 90% within 180 days in industrial composting conditions and leave no toxic residue
- EN 13432: European standard — equivalent requirements with slight variation in test protocols
- OK Compost HOME: Belgian certification for home composting at ambient temperatures — more accessible to consumers than industrial composting
- DIN CERTCO / TÜV Austria: Certification body marks that appear on packaging to demonstrate certified compostable status
Materials and Performance
Certified compostable bags use PLA (polylactic acid), PBAT (polybutylene adipate terephthalate), TPS (thermoplastic starch), and PHA (polyhydroxyalkanoate) in various blend formulations. Performance limitations vs. conventional plastic include lower heat resistance, limited moisture barrier performance, and higher unit cost — factors that must be evaluated against the sustainability benefit for each specific application.
Why Certification Matters for Compostable Claims
The compostable packaging market has significant greenwashing risk — materials marketed as compostable without certification may not biodegrade within any practical timeframe under real composting conditions. ASTM D6400 certification requires third-party testing demonstrating 90% biodegradation within 180 days at 55–60°C with no toxic residue. The TÜV Austria OK Compost INDUSTRIAL and OK Compost HOME marks are the globally recognized certification symbols that enable brands to make verified compostable claims on packaging. Without these marks, compostable claims are not substantiated under FTC Green Guides and carry regulatory risk.
Compostable Packaging Infrastructure Challenge
Industrial compostable packaging requires access to industrial composting facilities to achieve its certified end-of-life outcome. In the US, industrial composting infrastructure is concentrated in specific metropolitan areas — many consumers lack access to municipal composting programs that accept certified compostable packaging. For brands selecting compostable packaging, the end-of-life infrastructure question is as important as the material certification: home compostable materials (OK Compost HOME certified PHA and some PLA blends) provide a consumer-accessible composting pathway that industrial-only certified materials cannot.

Compostable Bags in San Jose — FAQs
What certifications should compostable bags carry?
Reliable compostable bags should carry ASTM D6400 certification (US standard) or EN 13432 certification (EU standard) demonstrated through certification body marks — TÜV Austria OK Compost INDUSTRIAL, DIN CERTCO, or BPI (Biodegradable Products Institute) certification. For home compostable claims, OK Compost HOME certification is the recognized standard. We provide certification documentation with all compostable bag orders.
Can compostable bags be used for food packaging?
Yes. Compostable bags for food applications use food-safe certified compostable materials meeting both FDA 21 CFR food contact requirements and ASTM D6400 compostability certification. PLA-based compostable bags are food-safe for ambient temperature dry food applications. For high-temperature or moisture-intensive food applications, barrier performance limitations of compostable films must be evaluated against the specific product requirements.
Do compostable bags cost more than conventional plastic?
Yes. Certified compostable materials currently cost 2–4× more per unit than equivalent conventional polyethylene bags. The cost premium reflects the higher cost of bio-based feedstocks and smaller production volumes compared to conventional plastic. As compostable packaging volume grows and bio-based feedstock economics improve, this premium is gradually reducing — current projections suggest cost parity with conventional plastic within 10–15 years.
What happens if compostable bags end up in landfill?
In landfill anaerobic conditions (no oxygen, limited microbial activity, low temperature), compostable materials biodegrade very slowly — significantly slower than in composting conditions. This is a fundamental limitation of compostable packaging: the environmental benefit is conditional on the material reaching a composting facility. Brands should communicate this limitation honestly to consumers rather than implying that certified compostable packaging is beneficial regardless of disposal method.
