blown film line from Rajoo

Constantia Creative Polypack, a part of Constantia Group, has recently installed a 5-layer POD blown film line from Rajoo Engineers Limited at its Kolkata plant. The line had a dream commissioning at Constantia’s Kolkata plant when the total start-up wastage was a mere 700 kg; many times lower to what they normally witness; a significant achievement of the Rajoo’s Pentafoil – 5-layer co-extruded blown film extrusion system.

The choice of Rajoo as a preferred brand to Constantia India, was the outcome of a total evaluation in terms of technical, commercial and service support and a survey covering all the suppliers. “A buyer needs to understand whether high-end specifications are essential or desirable, and its impact on the end product quality; consistency definitely is an important parameter that is always considered. Another crucial aspect that needs to be considered when it comes to deciding on a solution as this is the after-sales support, response to emergencies, costs of spares and services,” well explains Srikanta Khatua, head of operation ‘Creative Sub-Cluster’, Constantia Flexibles –India.

Khatua adds, “During the last years, we have also experienced Rajoo in context to its supply, service and support at the Puducherry plant. I must say, we were extremely satisfied.”

Time to identify the right technologies and its mix

“The agenda of ‘excellence in extrusion’ globally stems from the unique concept embarked on by Rajoo as offering ‘Appropriate Technology’ for business. For us at Rajoo, gone is the era to build specifications for competitive advantages, it’s now time to identify just the right technologies and its mix, to add value to the client business. Over specifications only add on to customer costs and not his business,” says Khushboo Chandrakant Doshi, executive director, Rajoo Engineers Limited.

The supply to Constantia included a blown film line with 5 grooved feed barrier screw extruders, hydraulically actuated screen changers, cylindrical spiral die (CSD) for film width of 2,500 mm, rated output of 750 kg/hour. The unique ‘flatness enhancer’, a first for the Indian industry, improved the film flatness for converting processes. A dual station fully automatic load cell-controlled surface winder was also an integral part of this solution. In addition, the supply to Constantia India also included an elaborate automation package including material conveying system, material dosing system, automatic thickness profile control and more.
