UFlex secures patent for waterborne heat seal coating
The coating is both eco-friendly and compliant with food contact regulations.

UFlex has secured an Indian patent (No. 567989) for its 'waterborne heat seal coating composition and a process for its preparation'. This coating is developed as a sustainable alternative to traditional fossil-based plastic coatings, aligning with the growing demand for recyclable and environmentally responsible packaging.
The coating is designed for heat-sealable applications, offering oil and grease resistance on kraft paper and suitable blister coatings for paper and paperboard. It is both eco-friendly and compliant with food contact regulations. This patented coating can be applied to various packaging materials, including food wraps, takeaway boxes, and blister packs for toys and personal care products.
One of the key advantages of this innovation is its user-friendliness. It is a ready-to-use formulation, which requires no dilution. It offers a low seal initiation temperature, excellent heat seal strength, and high hot tack strength, while meeting USFDA standards for food contact packaging.
UFlex’s chemical product portfolio has developed this product. It underscores the company’s extensive expertise in packaging inks, water-based, solventless, and solvent-based adhesives, as well as specialty UV/LED coatings. Its R&D center, accredited by NABL (ISO/IEC 17025:2017), is recognized by the Department of Science and Technology, Government of India. UFlex’s inks and adhesives business focuses on developing innovative products with sustainable technologies, customized products, and food-safe, toluene-free inks compliant with IS 15495:2020, while also providing on-site support.
