The breakthrough

Pullulan. Gelatin. Glycerol.
Three biopolymers. One impossible film.

For thirty years, packaging engineers have faced an iron tradeoff: high oxygen barrier means EVOH or aluminum foil — neither recyclable, neither compostable. Compostable alternatives traded away the barrier. We didn't accept the tradeoff. After 16 months and 25+ formulations, we found the synergy that makes EVOH-class compostable barrier real.

Why now

EVOH is on a 24-month collision course with regulation.

EU PPWR. Canada SUP. California, New York, Washington, Colorado. Mandates pending or live. Every major CPG brand has committed: recyclable, reusable, or compostable by 2025–2030. Nestlé. Unilever. Mondelez. JDE Peet's. The deadlines are not negotiable. The packaging is.

Brand commitments are the real pull. Coffee, snacks, jerky, pet food — every premium category has built its identity around quality and stewardship while shipping in EVOH-laminated waste. The dissonance has gotten expensive.

Pullulan is finally affordable. Production is moving from pharmaceutical-grade specialty to food-grade industrial. The unit economics work today. They get better as the feedstock scales. The window is open. It will not stay open.

Beachhead categories

We're starting where the pull is strongest.

01 · Coffee

Premium roasted coffee bags

The category competes on freshness and sustainability while shipping in EVOH. Bilayer 8–20 μm barrier on PBAT/PLA. 18-month shelf life. Our first prototype hit OTR 0.038 and EAB 287% — within commercial coffee specification on the first attempt.

02 · Jerky

Cured beef jerky wrappers

Brands position as natural snacking. They ship in non-recyclable barrier laminates. Trilayer architecture, 16% shrink at 65–75°C, WVTR 3.2 g/m²/day. The chemistry extends — proof the platform doesn't end at coffee.

Currently raising

$5M to PCT, validate, and land first paid pilots.

Three milestones. 18–24 months. PCT national-phase entries before the July 2026 deadline. Three diligence items closed. First paid pilot revenue from converters in coffee or jerky. Then Series A — or revenue, on our terms.
