India moves from PS to PP
Jun,2006

Equipped with an 800 mm die and 90 mm extruder for processing PP, with 50% regrind material, the line has an output of 230 kg/hr. "Overall there has been a shift from PS to PP for thermoforming of disposable containers because of the advantages the material offers.

The increased availability, lower prices, lower density compared to PS and the face that it is microwaveable and can handle hot products, are factors that have contributed to this shift," explained Sunil Jain, President of the company. The line incorporates a Maag melt pump and a continuous diverter type automatic screen changer and thickness monitoring system from German company Folitec.

Even so, the sheet line is not a new introduction from Rajoo. "We predicted that this would be the trend and were one of the first to develop specialist sheet lines for processing and thermoforming PP about four years ago," claimed Sunil. In fact, the latest line is an upgrade from an earlier introduction that had an output of 140 kg/hr. "The trend now is towards higher capacities," he added. The line was displayed with a hydraulically operated and computer programmable thermoformer "that has minimum mechanical parts and is considered to be the best in the industry."

The 21 mould cavity thermoformer was operating at 25 stroke / minute producing 30000 parts / hour. When asked if Rajoo's sheet line sales have been confined to the Indian market, Sunil replied, "No. A major breakthrough for us has been in Myanmar where we have supplied a sheet line and thermoformers for processing both PS and PP. We have also supplied a line to Persian Plastics in Iran.

For the production of pallet hood shrink and stretch film, Rajoo has introduced a three layer blown film line Multifoil RECF 2360-90 / 2100 IBC. "With an output of 400 kg/hr, the line incorporates all the automation features of the seven layer blown film line unveiled at Plastindia show," said Sunil.

The Indian manufacturer has also added gravimetric blenders to each extruder (from Germany based Plastcontrol), central hot air extraction systems on each extruder and a 500 mm INverted COnical Spiral Stack type die (INCOSS?). Also included is an automatic profile control air ring, oscillating thickness scanner, gusseting arrangement operating with an oscillating haul-off, center-surface-gap winder and a Plastcontrol computerized supervisory control with touch screen panel.

According to Sunil, the company is also working on introducing another innovation, which is a three layer wide width blown film line Multifoil RECF 2312 / 4200. "The line is an order from an Indian processor who is in the business of container liners. With 120 mm extruders and 1200 mm INCOSS?, the line is capable of producing a thickness of 0.2 mm and 5000 mm open lay-flat, with provision for gusseting, at an output of 600 kg/hr," explained Sunil.
