Seeing the machine cruise at a line speed of 207 mpm, really amazed the audience. With the extruder and dies coming from Rajoo and the coating and web-handling systems from Kohli, the convertors were assured of getting best of both the worlds. The convertors witnessed extensive benefits - be it technology, be it price or be in support.

Running different materials on the machines clearly indicated its versatility. The machine achieved a never-before milestone by producing a laminate of 10 micron PET film extrusion laminated with 15 and 18 gsm of PE, thus doing away with the blown film and adhesive based lamination process. For a customer, finally, the Rajoo-Kohli ECL machine clearly presented an ‘integrated solution’ to meet its needs with a ‘one stop solution provider. “Excellence in extrusion from Rajoo, the web-handling system of Kohli and the Rajoo experience of already supplying two ECL machines with line speed of 250 and 300 mpm to the same customer (Gopal Printpack) in the past have resulted in a product par excellence; the response of convertors at the open house enthused each one of us,” shared a very joyous, Khushboo Chandrakant Doshi, Executive Director, Rajoo Engineers Limited.

The demonstrated machine had screws with  diameter of 50 & 60 mm, screw length of 32 D, a die width of 1,450 mm with the width range of 600 – 1,300 mm. The plasticising capacity of the extruder was 140 kg/hour for 60 mm and 90 kg/hour for 50 mm with the coating range being 10 - 40 gsm. The gsm variation for a 10 micron PET/22 micron metallised CPP structure was below 5% for a deposit of 9 gsm of PE melt. The anchor coating dry gsm was controlled within 0.05. 

The showcased line capabilities included extrusion coating and laminating of film, paper and aluminum foils; surface treatment by corona treating and chemical priming; process capabilities for LDPE, LLDPE, ionomer, PP, EVA, EMA, EVOH and others; single and tandem automatic die stations, with or without co-extrusion; co-extrusion using universal feed-block technology and extruder size selection to meet process requirements for output and coating thickness.

Spread over  2 days, the open house included  detailed demonstrations of the Rajoo-Kohli Lamex 207 (ECL line) , a tour to witness the acclaimed manufacturing of the Rajoo shop floor and Rajoo Innovation Centre as well as the visit to earlier supplied two ECL lines made by Rajoo, successfully operating at Gopal Printpack  in Rajkot.

The lines showcased caught the customer delight and fancy, so much so that  prospects saw immense value in the equipment.

The flexible packaging industry’s demands were clear; their needs of Extrusion Coating and Lamination Machines were growing and growing fast. They were looking beyond the available solutions at reasonable price points. The best-in-class extrusion and proven web solutions needed to integrate to provide a system that would meet Industry’s needs of today and be versatile enough to be adapted for future requirements.

 In an Extrusion Coating and Laminating machine (ECL in short) a water-based lacquer  is coated on a primary substrate through the gravure process followed by a deposit of PE / PP based molten polymer from a T-Die and then combined with yet another substrate to form a composite laminate. This technology is rapidly replacing many a solvent-based and solvent less laminating applications.

 Rajoo Engineers (well known for bringing in world-class extrusion technology at affordable prices and have developed India’s first three layer feed block and 1600 mm extrusion coating die with internal deckling to reduce edge bead) and Kohli Industries (leaders in rotogravure printing and laminating machines for the flexible packaging industry with a footprint in over 30 countries), comprehended this industry need, and in the best interest of the industry, joined hands to create a formidable alliance to build and maintain one of the most advanced and versatile  Extrusion Coating and Lamination machines.

 As good a product, it needs to reach out to the converters of the flexible packaging industry and there comes in Multigraph Machinery Co. Ltd. (promoted by owners of Manugraph- world’s  renowned offset machine producer) to promote the sales of this first-of-its kind alliance  product on a PAN India basis.

 
“We are excited at this alliance as each one of us would bring in key technology and skill sets for this business to succeed; working to our strengths is the need-of-the-hour. The symphony of three corporate Rajoo-Kohli-Multigraph will foremostly demonstrate to the industry the thought-provoking leadership; product leadership is bound to follow,” emphasise Utsav Doshi and Khushboo Chandrakant Doshi, Executive Directors of Rajoo Engineers Limited.
