Constantia buys Bobst Expert K5 for Ecoflex plant in Ahmedabad

World's first metallizer for ultra high-barrier MDO PE solution

High barrier PE recyclable solution in Constantia’s EcoLamHighPlus laminates which now has RecyClass approval in Europe

Parikh Flexibles, part of the Constantia Flexibles Group has purchased an Expert K5 1350mm to be installed at a new greenfield facility Ecoflex, Ahmedabad in India in 2021. This specially designed narrow-width Expert K5 will produce Ultra High Barrier PE film meeting market requirements for a sustainable, fully recyclable flexible packaging solution as a replacement for aluminum foil. The Ecoflex plant produces recyclable packaging materials based on PE films produced on a Hosokawa Alpine blown-film line at the new plant.

The purchase reinforces the strong collaboration between Bobst and Constantia which contributed to creating the world’s first high barrier PE recyclable solution in Constantia’s EcoLamHighPlus laminates which now has RecyClass approval in Europe.

Narrow Width Metallizer for the Converter Market

The Expert K5 has been specially designed and is the first-ever Expert K5 at 1350mm width. The machine has all of the unique features of this well-established model along with newly optimized features, all in a smaller package perfect for the production of MDO PE film.

With the largest coating drum in the industry at 700mm; the Expert gives an increased collection efficiency of 16% and along with the High Rate Source provides better coating uniformity. The 1350mm model has new state of the art optimized web handling, tension control, thermal management system, and barrier enhancing features to enable the production of PE-based film for foil replacement.

The machine also incorporates the Bobst AluBond and Bobst Hawkeye unique innovations. The AluBond process provides high metal adhesion with values up to 5N/15mm as well as enhancing oxygen and water vapor barrier levels on films including MDO PE, BOPP, and CPP. Bobst Hawkeye is an in-line optical density deposition control system that at full metallizer speed, detects, counts and categorizes pinholes and other defects from 0.1mm upwards with remote reporting ensuring no interruptions to production.

Commenting on the purchase, Pragnesh Shah, head of Plant at Constantia Parikh said, “We have worked with Bobst for some time in the quest for fully recyclable metalized film suitable for foil replacement. We needed a machine to enable us to produce our EcoLamHighPlus laminates. The Bobst Expert K5 is perfect for our requirements. We look forward to having the machine installed in our new plant in India next year and to continuing our collaboration with Bobst.”

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.
