Greendot Biopak’s expanded bio-based coatings challenge plastic liners in food packaging

INDIA – Greendot Biopak has strengthened its focus on 100 percent bio-based and home-compostable aqueous barrier coatings for paper packaging, as India and Europe tighten rules on single-use plastics and synthetic liners used in foodservice products.

The company’s coatings use renewable raw materials including starch, plant proteins, seaweed extracts, cellulose, waxes, oils, and minerals.

Rajen Bhagyoday, founder of Greendot Biopak, explained that packaging requirements are changing rapidly, especially in food delivery and quick-service restaurants.

He noted that brands need solutions that deliver barrier performance and food safety while aligning with global regulation.

Performance That Rivals Plastic

Greendot’s coated solutions deliver oil and grease resistance in the 14-16 Kit range, heat sealability between 80°C and 160°C, and high repulpability.

These properties suit applications from takeaway boxes to flexible paper-based formats.

The coatings are compliant with EN 13432 and IS/ISO 17088 for home compostability.

Regulatory Winds Shift Across Continents

Europe’s Single-Use Plastics Directive has accelerated the move away from paper products that use synthetic polymer linings.

Proposed revisions to the Packaging and Packaging Waste Directive require all EU packaging to be reusable or recyclable by 2030.

Under SUPD, paper containing a synthetic lining may be restricted if that layer cannot be easily separated during recycling. Greendot’s bio-based coatings provide superior barriers without banned ingredients, qualifying for exemption.

India Follows Suit

The Indian market is moving in the same direction. Enforcement around single-use plastics and Extended Producer Responsibility is strengthening, with plastic-coated solutions drawing greater scrutiny.

Bhagyoday emphasized that this is why the company has focused on pioneering compostable aqueous barrier coatings based on 100 percent biobased, natural, unmodified plant polymers.

The company’s solutions are backed by ISEGA food-contact testing, PFAS-free validation, and migration testing.

The Bottom Line

For the packaging industry, Greendot Biopak’s push into bio-based coatings signals a decisive shift away from synthetic barriers that complicate recycling and compostability.

As both Indian and European regulators tighten restrictions on plastic-coated paper products, solutions that combine barrier performance with genuine end-of-life pathways become not just preferable but necessary.

The message is clear: the era of plastic liners hiding in paper packaging is ending.
