UFlex Earns Indian Patent for Eco-Friendly Waterborne Heat Seal Coating for Food and FMCG Packaging

UFlex Ltd., the largest multinational flexible packaging and solutions company in India, remains ahead of the curve with its commitment to innovation and sustainability as fundamental to its business strategy. UFlex has received an Indian patent (Patent No. 567989) for its innovative “Waterborne Heat Seal Coating Composition and a Process for Its Preparation,” a true milestone in its R&D capabilities, and major step forward in the sustainable reduction of the environmental footprint of packaging materials. Additionally, UFlex will further solidify its reputation as a global champion of eco-friendly opportunities that will ultimately change the world of packaging technologies.

Discovering and Delivering Sustainable Solutions
The new patented coating is positioned as a sustainable successor for conventional fossil-based plastic coatings in response to the global demand for recyclable, biodegradable, and food-safe packaging. Plastic coatings effectively ha dented the circular economy as there are recycling and end-of-life considerations associated with conventional plastics and its coatings for a long time. UFlex has offered a waterborne composition to replace those materials with an environmentally sound building block that does not sacrifice on the functionality or performance required of modern packaging applications.

Notably, the coating is formulated for heat-sealable applications and exhibits excellent oil and grease resistance—key requirements for food-grade and takeaway packaging. It also provides effective blister coatings for paper and paperboard substrates, thereby opening possibilities in pharmaceutical, personal care, toy, and fast-moving consumer goods (FMCG) packaging segments. Whether used for food wraps, meal trays, disposable takeaway boxes, or blister packaging, this technology offers broad compatibility and practical value.

Functionality Meets Efficiency
One of the standout features of this new coating composition is its user-friendly, ready-to-use formulation. Unlike traditional coatings that may require dilution or precise mixing, UFlex’s product simplifies operations for packaging converters. It boasts a low seal initiation temperature, ensuring efficient processing and energy savings during sealing. In addition, it offers high heat seal strength, exceptional hot tack strength, and maintains performance integrity across various substrates.

The coating has been tested and proven to be compliant with USFDA standards for food contact, giving manufacturers the confidence to adopt the product in food-grade packaging without regulatory concerns. This compliance aligns with UFlex’s broader goal of developing safe, sustainable, and compliant products for global markets.

Backed by R&D Excellence
This innovative development emerges from UFlex’s robust chemicals business vertical, which is known for its advanced portfolio including packaging inks, water-based, solvent-less, and solvent-based adhesives, as well as UV/LED coatings. These products are not only high-performance but also designed with an eye on sustainability, safety, and customisation for a wide variety of industries.

Central to this success is the company’s state-of-the-art R&D center, which is NABL-accredited (ISO/IEC 17025:2017) and recognised by the Department of Science and Technology (DST), Government of India. This research facility plays a critical role in fostering breakthrough innovations and providing technical support to both domestic and international clients.

A Vision for the Future
The granting of UFlex’s patent is an important step in UFlex’s vision for the future that includes green, efficient, high-performance packaging solutions that are aligned with worldwide sustainability goals. UFlex’s chemicals arm is also continuing its endeavor of making toluene free inks, low-VOC based adhesives, compostable coatings, and other specialty products that meet the legislative needs and expectations of the evolving environmental landscape.

UFlex inks and adhesives business continues to focus on IS 15495:2020 standards to ensure that inks are safe and non-toxic for food packaging and suitable for direct food contact. UFlex will continue to provide on-site technical assistance, as UFlex is not just a product provider in the packaging ecosystem, but a solutions provider.

A Leader in Green Innovation
This patented waterborne heat seal coating is much more than a new technology: it is a testament to UFlex’s dedication to leading the change towards a circular economy. Sustainability has become a baseline requirement in product design and development; innovations like these exemplify UFlex’s commitment to supply solutions for business, consumers, and the planet.

As the world transitions toward more sustainable consumption and production, UFlex will continue to innovate at the crossroad of science, sustainability, and industrial use, allowing the packaging industry to lead the way to a performance-based and sustainable future.
