UFlex, an Indian multinational flexible packaging company, has secured an Indian patent (number 567989) for its waterborne heat seal coating composition and a process for its preparation. This innovation provides a sustainable alternative to traditional fossil-based plastic coatings, addressing the growing need for recyclable packaging solutions.
The coating is for heat-sealable applications, offering oil and grease resistance on kraft paper and suitable blister coatings for paper and paperboard. It adheres to food contact regulations. This patented coating can be applied to packaging materials, including food wraps, takeaway boxes, and blister packs for toys and personal care products.
A key advantage of this innovation is its user-friendliness; it is a ready-to-use formulation. It offers a low seal initiation temperature, heat seal strength, and hot tack strength, while meeting United States Food and Drug Administration (USFDA) standards for food contact packaging.
This solution from UFlex’s chemicals portfolio highlights the company’s expertise in packaging inks, water-based, solvent-less, and solvent-based adhesives, and speciality ultraviolet/light-emitting diode (UV/LED) coatings. Its National Accreditation Board for Testing and Calibration Laboratories (NABL), ISO/IEC 17025:2017 accredited R&D centre is recognised by the Ministry of Science and Technology, Government of India. UFlex’s inks and adhesives business focuses on developing solutions with sustainable technologies and customised products.
