Tresu at Sino Corrugated 2015

Print-converting line for enhanced flexo process control

For common impression flexo printing situations, the F10 iCon ink supply system automates ink pressure and viscosity in flexo printing machines

Tresu Group emphasized its capability as a total flexo solutions provider at Sino Corrugated 2015, China from 14 to 17 April, with an offering that comprises ancillary products for ink and varnish flow control, integrated printing and coating units, and complete multi-station lines for packaging and lottery tickets. Stand highlights will include the unveiling of the modular ‘Concept’ press, the light-weight corrosion-resistant carbon-fibre chamber doctor blade, and the F10 iCon ink supply system.

Customized to end-user performance requirements and built with Tresu’s 30 years of press building and engineering expertise, the Concept offers a flexo platform in 900 mm, 1,100 mm and 1,400 mm widths. In addition, it provides the possibility for seamless integration of processes, such as variable data, gravure, screen, hot and cold foil and finishing, providing an end-to-end solution for highvalue packaging. Running at speeds of up to 600 metres a minute, the Concept can convert substrates up to 600 micron thickness, including paper, board, aluminium foil and flexible packaging.

Allan Sander, vice-president of Tresu Solutions, says, “China’s packaging converters face growing demand for shorter runs as well as high quality from brand owners and retailers. In-line flexo provides the most effective way of offering service flexibility while maintaining the competitive edge in terms of productivity, waste reduction, footprint and ergonomics.”

Lightweight carbon fibre chamber doctor blade

Tresu’s full range of ancillary solutions, comprising chambered doctor blades, supply systems and chilling equipment, offer full, automated, enclosed ink circulation, at controlled flow, pressure and viscosity. A highlight of the Tresu stand is the new programme of lightweight carbon fibre chamber doctor blade systems, which offer improved chemical resistance, optimized flow and safe, easy handling in virtually all flexo printing situations.

Enclosed chamber technology to enhance process control

Common to all Tresu chamber doctor blade systems are the company’s patented seal systems and two-minute blade change capability. As well as being integral to the Concept, Tresu’s ancillary equipment is a feature of the flexo presses of many original equipment manufacturers. The enclosed environment, resulting from the seal and precise blade positioning, ensures pressure and flow rate are maintained at desired levels without manual intervention. This stops air contaminating the chamber and results in foam-free transfer of ink and coating directly to the anilox cells, also at fast speeds. The enclosed chamber also prevents solvents from escaping and protects the ink from degradation due to exposure to the atmosphere.

F10 iCon ink supply system

For common impression flexo printing situations, the F10 iCon ink supply system automates ink pressure and viscosity in flexo printing machines. This, in turn, ensures a constant, accurate ink density on the printed substrate and prevents air from contaminating the ink chamber. The energy-efficient system also provides thorough fully automatic cleaning, removing ink and residue from the chamber, achieving a complete ink change cycle in five to ten minutes.

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 to inspire and mobilize our editorial and advertising teams!
