Certified Compostable

Kraft/PLA and cellulose builds that return to soil within 180 days. Barrier data, certification standards, and honest limits — all on one page.

Verified Claims
  • Seed logo (EN 13432 / AS 4736) for industrial composting
  • AS 5810 + TUV OK Compost HOME for home-compostable structures
  • Barrier caps at ~70% of aluminium foil — we print that number on the page
  • 60-150 um total thickness across duplex to quad structures
  • OTR 1-15 cc/m2/day — depends whether a high-barrier coating and/or metallisation is added
  • WVTR <80 (cellulose) down to <1 g/m2/day (metallised)
Limits
  • -Shelf life 12+ months on a high-barrier build — an aluminium foil laminate still reaches 18-24 months
  • -High fat/oil fillings need a barrier review first — 12+ months is not automatic
  • -Kraft/PLA = industrial composting only — not home compostable
  • -Real-world decomposition: 90-180 days in controlled industrial facilities
  • -BPI logo sublicense costs ~$3,000/yr — we flag it before artwork starts, not on the invoice
