New Delhi, 6 October 2022 – As one of the global leaders in inks, coatings and adhesives for packaging and labelling applications, the UFlex Chemicals Business recently acquired a patent for ‘Solvent free pigmented adhesive and a process for its preparation’ (Patent No 406417). With this patent, the Chemicals business of UFlex has again demonstrated its commitment to ‘Harvesting Innovation.’

This patent has been awarded to UFlex by the Government of India in accordance with the provisions of the Patents Act, 1970 for a period of 20 years. UFlex proudly adds this patent to develop innovative and sustainable solutions to its growing list of leading-edge products.

The present disclosure relates to a two component adhesive composition and the process for its preparation. The adhesive composition of the present disclosure is solvent-free and works well on existing solvent less lamination machines. It helps reduce the use of white ink, thus significantly reducing costs. The process for the preparation of the adhesive composition is simple, efficient, solvent-free and environment friendly.

The presence of high content of volatile organic solvents in solvent-based conventional adhesives is detrimental to the environment and is energy intensive, thereby increasing overall costs. With the development of this solvent free white adhesive, the customer gets the freedom to be greener and more cost-effective simultaeneously.

Patented solvent-free pigmented white adhesive – advantages

The newly patented adhesive will help achieve higher lamination speeds ranging from 300 to 350 meters per minute, leading to higher productivity with excellent machinability on existing solvent-less lamination machines. Its use will also cut down the requirement of white ink coating on printed substrates, leading to substantial cost savings.

The solvent-free pigmented white adhesive offers excellent wettability, enhanced wettability on metallized substrates and improves the visual effect of the flexible packaging. The development of the solvent-free pigmented white adhesive consumes less power and significantly reduces application costs. The fast decay of primary aromatic amines makes it highly environment friendly and sustainable.

On acquiring the adhesive patent, Rajesh Bhasin, joint president, UFlex Chemicals stated, “Continuously developing cost-effective and value-added solutions for the packaging industry is integral to our business. Our research team has been continuously working most diligently to outperform our own set benchmarks. This patent is another feather in the cap of UFlex Chemicals, and once again demonstrates our capability to align with client needs while promoting sustainability. I am thrilled that a cost effective and a versatile solvent-free white adhesive is now a reality we will be able to deliver.”

Consumer product brands can be highlighted with distinctive visibility as the new pigmented adhesive considerably improves flexible film performance allowing for higher visual appeal in applications. The product is already being marketed globally and is garnering good demand from customers.

Packaging South Asia — resilient, growing and impactful — daily, monthly — always responsive

The multi-channel B2B in print and digital 17-year-old platform matches the industry’s growth trajectory. The Indian, South Asian, Southeast Asian, and Middle East packaging industries are looking beyond the resilience of the past three years. They are resuming capacity expansion and diversification, with high technology and automation in new plants and projects.

As we present our 2024 publishing plan, India’s real GDP growth for the financial year ending 31 March 2024 will exceed 6%. The packaging industry growth will match the GDP growth in volume terms and surpass it by at least 3% in terms of nominal growth allowing for price inflation in energy, raw materials, consumables, and capital equipment.

The capacity for flexible film manufacturing in India increased by 45% over the past four years. With orders in place, we expect another 20% capacity addition in 2024 and 2025. Capacities in monocartons, corrugation, aseptic liquid packaging, and labels are grown similarly. As the consumption story returns over the next six months, we expect demand to return and exceed the growth trajectory of previous years. The numbers are positive for most of the economies in the region – and as shown by our analytics, our platform increasingly reaches and influences these.

For responsible and sustainable packaging, with its attendant regulations and compliances, there is significant headroom to grow in India and the region. Our coverage includes the entire packaging supply chain – from concept to shelf and to waste collection, sorting, and recycling.

We target brand owners, product managers, raw material suppliers, packaging designers and converters, and recyclers. This is a large and complex canvas – the only thing that can work is your agile thinking and innovation together with our continuous learning and persistence.

The coming year looks to be an up year in this region, and this is the right time to plan your participation and marketing communication – in our rich and highly targeted business platform with human resources on the ground. Share your thoughts and plans and to inspire and mobilize our editorial and advertising teams!
