Most paper food packaging is not really paper. Wrappers, sachets and cups carry a thin layer of plastic that keeps out grease, moisture and oxygen, and that layer is what makes them hard to recycle. Lactips, founded in 2014 near Saint-Étienne on research from the Université Jean Monnet, makes an alternative from casein, the main protein in milk: a material that behaves like plastic in use, dissolves in water and biodegrades.
The European Innovation Council paid €2,393,912 towards a two-year project to turn it into coatings for paper food packaging. The technical results were strong. Since then Lactips has raised €16 million and is doubling its factory. It has also lost about €4.5 million a year, and does not publish its revenue.

What Lactips Does Today
Lactips is now an industrial company rather than a lab. It has produced since late 2021 in a factory on a former dairy site in Saint-Paul-en-Jarez, and sells pellets of its protein-based material to packaging makers. In November 2024 it raised €16 million led by SWEN Capital Partners' Blue Ocean fund, with GO Capital's Impact Océan Capital, Bpifrance's SPI fund, BNP Paribas Développement and Sogive. It said the money would fund commercial development in Europe, expansion into the United States and Japan, R&D and production capacity. It then had 50 employees.
Capacity is growing too. As the only winner in the Auvergne-Rhône-Alpes region of France 2030's "first factory" call, Lactips is installing a second production line by 2026 in a €10 million project, 30% of it subsidised, according to Le Journal des Entreprises.
The Technology: Plastic Made From Milk Protein
Lactips' core invention is a process that turns casein into a thermoplastic, a material that can be melted and processed on standard plastics equipment, while keeping the properties that make it useful for packaging: it blocks oxygen and grease and can be heat-sealed.
For ECOLACTIPACK the company applied it as a coating on paper. The CORDIS report claims oxygen, grease and sealing performance "comparable to conventional plastics", recovery of approximately 100% of the paper fibre because the coating dissolves in the recycling water, and biodegradation within 30 days. It also describes hybrid and fully plant-based formulations, meant to improve the material's life-cycle footprint beyond a dairy raw material.
What the EIC Project Promised, and What CORDIS Shows
The project ran from 1 January 2022 to 31 December 2023. Its goal was a material that would "unlock plastic-free paper packaging for food": single-layer coated paper that protects food, can be recycled with paper and biodegrades. The report says brand owners could now buy the material as pellets and that commercialisation was planned for 2024.

What Has Happened Since the Award
The Money
Lactips publishes its accounts but keeps its revenue confidential. The net results reported by Societe.com and Pappers show a steady loss of just under €4.5 million a year: €4.08 million in 2021, €4.48 million in 2024 and €4.61 million in 2025. The register lists no insolvency proceedings.
Scale is the test
A factory, a second line and a €16 million round are signs of investor confidence. But the losses have not narrowed as the company moved from R&D to production, and without published sales it is impossible to tell how close the business is to covering its costs. The second line only pays off if packaging makers commit to volumes.
Why Europe Should Care
The EU's packaging rules push in Lactips' direction. The Packaging and Packaging Waste Regulation aims to "make all packaging on the EU market recyclable in an economically viable way by 2030"; it entered into force in February 2025 and applies from 12 August 2026. Plastic-coated paper is harder to recycle than plain paper, and a coating that dissolves in the recycling water is designed to remove that obstacle. Lactips is also an example of EU and French public money working together: two EU grants (including €1.49 million for ECOLACTIFILM in 2017 to 2019), a state-run fund among its investors and a France 2030 subsidy for its factory.
What the project promised
A milk-protein coating that makes paper food packaging plastic-free, recyclable and compostable, on the market from 2024.
What the record shows
Strong reported material performance, a growing factory and fresh capital, but steady losses of about €4.5M a year and no public sales figures.
The Verdict
Proven material, unproven business
ECOLACTIPACK did what it set out to do in the lab and the pilot line, and Lactips has since secured the money and the capacity to sell at industrial scale. What the public record does not show is whether the market is buying. The company's losses have been flat for five years, and until it reports revenue, the EU's bet remains a bet on potential rather than on sales.
