Efficiency from fully loaded lines

A wide range of blown film lines are now available offering processors with better options and higher level of efficiency in their operations. The current portfolio of blown film extrusion lines is a reflection of how this sector of the plastics industry has grown over the years. Responding to the processors' requirements for improved end-product, lower wastage and energy saving encouraged most manufacturers to incorporate tightly integrated and latest motion control techniques to reduce gauge variation, ensure more accurate layer thickness ratio in multilayer films, improve motor life, and implement repeatability and data recipe recall to reduce cost and waste and to save precious resources. Market trends clearly show the foods industry's growing demand for packaging that prolongs the shelf-life of packaged goods. This mainly concerns lidding sheets for laminating to BOPP, BOPET and BOPA, thermoforming sheets, bag-in-box packages and bags of all types. It should be noted that 7-layer film is the established standard in the market today. The migration to 9-layer technology is driven by improved film characteristics, downgauging and cost savings. Promised high productivity The broad portfolio from Rajoo Engineers Ltd. includes monolayer upward extrusion film lines with small mono-block construction of 500mm film width up to wide width film of 5000mm. The product range in downward blown film extrusion is also with monolayer and multilayer options. Multilayer upward extrusion blown film lines from 2 layers to 7 layers are offered covering film widths from 1000mm to 5000mm. Rajoo blown film lines come with high productivity and quality levels through accurate web tension and winding tension control allowing high take off speeds during extrusion and in subsequent converting processes. High-tech and appropriate ancillaries are easily integrated due to connectivity and communication. The varieties in materials and film structures that can be processed are almost unlimited. For film widths of 3300 mm, Rajoo recently launched multilayer blown film lines with oscillating haul off and fully automatic winder - a technology until now available only from European/American machinery manufacturers. Rajoo machines provide the required versatility, adaptability and diversity and these advantages are being increasingly appreciated worldwide. Continuous contact with the reputed resin suppliers and processors gives Rajoo the insight to remain in step with the latest market trends. Also, with research and development being the key to its success, the company maintains a design development team composed of 22 highly qualified engineers from various disciplines like mechanical, plastics, electrical, mechatronics, electronics and instrumentation. The use of latest engineering tools like NX and SolidEdge for mechanical design and special melt flow simulation software improvises not only the specific extrusion solutions but also facilitates transfer of intact design solutions data to CAM. The manufacturing facilities are highly integrated with low level of outsourcing to ensure quality and tight delivery schedules. Whether it is barrier film or lamination film, versatile multi-layer blown film lines from Rajoo are being further improved to suit new market requirements. Rajoo blown film lines suppor t innovat ive combinat ions of expensive and inexpensive resins in blown film layer structure for significant cost saving. "We have continuously achieved spectacular growth in sales year after year which itself is evidence of our acceptance wor ldwide as rel iable suppliers. In machinery business, brand name is important which takes years to build and today Rajoo is accepted as an affordable world class extrusion machinery supplier.
