The UFlex Cylinder Division in Noida is well-known as a trusted manufacturer of rotogravure printing cylinders for flexible packaging. Although the division’s capabilities extend from gravure printing cylinders to flexo plates and flexo printing sleeves, it is still the leader in automation and the capability of producing cylinders for water-based gravure using its Think Labs robotic engraving system.

On our 7 February 2021 visit to the UFlex Cylinder Division in Noida, we met with Parwez Izhar, chief executive officer of cylinder business and senior vice president at UFlex, who showed us the plant and explained the working of the gravure aspect as well as the addition of the new Kodak Flexcel NX system which modernizes and expands the division’s flexo platemaking capabilities and capacity. The company’s strength comes from upgrading and acquiring the latest technology to meet the most critical demands of its customers. 

The cylinder division’s gravure engraving capabilities include both the electro-mechanical engraving lines and the Think Labs robotic laser engraving line. In the robotic laser engraving line or system, robots do the entire process of preparing, engraving, and finishing the cylinders in a special air-conditioned and dust-proof enclosure controlled by the technical staff using the digital files sent by the prepress team. The process of engraving and finishing is entirely automated while the programming or instructions and specifications for each cylinder are provided by the technical staff.

The robotic engraver is more productive and sustainable

By comparing the preparation of cylinders in both manually and by the robotic system, we learned that the VOC levels of the robotic engraving line section are 25-30% less than the electro-mechanical section, making it healthier and more sustainable. Moreover, in the robotic engraving line, the energy-saving and efficiency are higher, the cylinder life is better, and the system needs less manpower.

At the same time in gravure printing with cylinders with cell patterns that use less ink while maintaining high quality which makes customers happy with the results and the savings. Currently, the single robotic line can produce 80 cylinders daily, whereas with the cylinder division’s multiple electro-mechanical engravers can produce 250 cylinders daily.

Izhar spoke about the trends for modernization in gravure, “Customers in the flexible packaging industry prefer the cylinders with low gsm or low ink consumption. We also use make gravure cylinders for printing with water-based inks, so that the VOCs are low and eco-friendly. This brings us and our customers closer to the sustainability goals. Today, the trend is for the use of water-based inks in gravure, and we are the best in producing the cylinders for printing with water-based gravure inks as we use the Think Lab robotic engraving line to produce them.” Increasingly UFlex’s packaging division, as well converter customers of the cylinder division are engaged in the trend for gravure printing with water-based gravure inks.

Izhar concluded our conversation by commenting on the company’s achievements during the Covid-19 pandemic, saying, “When the second wave of the pandemic hit India, we faced many challenges as our operations and the supply chain was affected. We were unable to get the base shells, which are the raw material for cylinder making. As there was a shortage of oxygen cylinders, we informed our manufacturing units to buy plasma arc cutting machines. Our capacity was compromised, and that’s why Q1 was not good for us, but as the situation improved, we made record sales in Q2 and Q3. The reason is that Covid-19 increased the demand for packaging, so we were able to produce more engraved cylinders.” 

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 growing 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.
