Practical guide to sustainable packaging materials — recycled board, biodegradable films, compostable pouches and FSC certification for B2B buyers.
Sustainable packaging has moved from a marketing differentiator to a procurement requirement. Major retailers including Walmart, Tesco, Target and Amazon all have published packaging sustainability targets that directly affect their supplier packaging specifications. Understanding which eco claims hold up under scrutiny — and which do not — helps buyers choose materials that satisfy both marketing goals and supply chain reality.
Post-consumer recycled (PCR) content in packaging board is one of the most credible sustainability claims because it has a measurable, verifiable content percentage. Key options:
| Term | What It Means | Standard |
|---|---|---|
| Biodegradable | Breaks down biologically — no time frame specified | No universal standard; claim is largely unregulated |
| Industrially compostable | Disintegrates in industrial compost (58°C+) within 12 weeks | EN 13432 (EU), ASTM D6400 (US), AS 4736 (AU) |
| Home compostable | Disintegrates in home compost (ambient temp) within 6–12 months | AS 5810 (AU), TÜV OK compost HOME |
| Oxo-degradable | Plastic with pro-oxidant additives; breaks into microplastics | Banned in EU as of 2021; not recommended |
Forest Stewardship Council (FSC) claims require chain-of-custody evidence, the correct product scope and approved trademark use. For B2B buyers, verify the certificate holder against the contracting supplier and require the claim on the order and sales documents. BestPackFactory has not yet supplied documentary evidence linking FSC record SGSHK-COC-332603 to Shenzhen Color Printing Paper Packaging Co., Ltd.; it therefore must not be presented as a current factory-held credential or used to promise FSC-labelled cartons until that relationship is documented.
Compostable stand-up pouches and flat pouches are available in PLA/PBAT laminates. These structures are certified to EN 13432 for industrial compostability. Key limitations: barrier performance is lower than conventional BOPP/VMPET/PE (typical shelf life 6–9 months for dry goods); seal strength is slightly lower; and the material requires industrial composting infrastructure to actually decompose — home disposal in landfill results in the same outcome as conventional plastic. Use compostable flexible packaging when your customers have access to industrial composting collection.
