TRESU to demonstrate the productivity of its iCoat flexo coater

TRESU Group to share space with HP

The TRESU iCut plate cutter provides a fast means of imaging flexo plates for the post-print spot coating of digitally printed folding cartons

At interpack 2017 on the HP stand, TRESU Group will demonstrate the productivity of its iCoat flexo coater for applying added-value varnishes to digitally printed folding cartons and synthetic materials, seamlessly inline with an HP Indigo 30000 digital press.

TRESU iCoat applies TRESU’s private label iVarnish range of UV-curable or aqueous varnishes, optimised to offer excellent adhesion properties on both plastic as well as board substrates. It has a maximum speed of up to 4,600 sheets per hour, handling substrates of maximum format 750 mm x 550 mm in paperboard and metallised boards between 250 micrometers and 600micrometers. It also accommodates PVC and polypropylene substrates up to 630 micrometers, and PET substrates up to 400 micrometers. The coater also comes with quick-change sleeve technology and automatic chamber cleaning, enabling varnish changeovers within minutes. Its sleeves assure smooth production without mis-registration at maximum speeds equivalent to that of the HP Indigo 30000.

“Coating is a vital post-print stage in the digital packaging printing process, ensuring the finished product is both resistant and aesthetically appealing. The TRESU iCoat coater integrates perfectly with the HP Indigo digital press, applying full and spot varnishes in perfect register with minimal makeready time, and the result is a high-speed single-pass line with minimised waste or logistics,” Kim Krintel, vice president, TRESU Digital Solutions says.

interpackA TRESU innovation for the digital workflow to be used with TRESU iCoat demonstrations at interpack 2017 is TRESU iTape, a double-sided adhesive, developed in partnership with Lohmann Bonding Engineers, of Neuwied, Germany. Benefits are superior dot gain control and varnish transfer, and fast frictionless demounting, eliminating the possibility of causing sleeve damage. Besides the TRESU iCoat coater, TRESU provides a complete workflow of consumable products and equipment including coating media and tapes, coating circulators and sleeve cutters. There are also twin-unit and inkjet coating machines.

The TRESU iCut plate cutter provides a fast means of imaging flexo plates for the post-print spot coating of digitally printed folding cartons. TRESU iCut is designed to process the same software as the digital printer, as well as the accompanying analogue coater. Processing times are less than ten minutes. Once imaged, the plate, together with the sleeve, are ready to be mounted on the coater for production.

TRESU’s iCoat 30000 TWIN, featuring two flexo coating units, applies a combination of aesthetically appealing spot, line, matte and gloss varnishes in a single pass.

The impact, resilience, and growth of responsible packaging in a wide region are daily chronicled by Packaging South Asia.

A multi-channel B2B publication and digital platform such as Packaging South Asia is always aware of the prospect of new beginnings and renewal. Its 16-year-old print monthly, based in New Delhi, India has demonstrated its commitment to progress and growth. The Indian and Asian packaging industries have shown resilience in the face of ongoing challenges over the past three years.

As we present our publishing plan for 2023, India’s real GDP growth for the financial year ending 31 March 2023 will reach 6.3%. Packaging industry growth has exceeded GDP growth even when allowing for inflation in the past three years.

The capacity for flexible film manufacturing in India increased by 33% over the past three years. With orders in place, we expect another 33% capacity addition from 2023 to 2025. Capacities in monocartons, corrugation, aseptic liquid packaging, and labels have grown similarly. The numbers are positive for most of the economies in the region – our platform increasingly reaches and influences these.

Even given the disruptions of supply chains, raw material prices, and the challenge of responsible and sustainable packaging, packaging in all its creative forms and purposes has significant headroom to grow in India and Asia. Our context and coverage engulf the entire packaging supply chain – from concept to shelf and further – to waste collection and recycling. We target brand owners, product managers, raw material suppliers, packaging designers and converters, and recyclers.
