Buying a standard Blown Film line, is a concept of the past, a range to choose from (Economic, Balanced and Advanced) with enormous flexibility within the range helps you PICK just the right machine to fit your needs; this revelation from Rajoo, will completely redefine the market dynamics.

The distinction continues at K 2013 as well! At K 2013, Rajoo would proclaim to the world its unique business approach for processors and convertors as a ‘One Stop Solution Provider’. The pre-sale consultative approach will come with a newer dimension

when customers will be updated with the three broad solution categories offered by Rajoo for Blown Film lines – Economical, Balanced and Advanced. Named simply to suit their positioning, each of the ranges comes with adequate options for further personalisation.

Every solution comes with different price-points. Very clearly, the Economical Model (produced mostly indigenously) provides the best value proposition to the buyer. ‘It is very important to understand needs. You would be surprised to know that 80% of the films can be very conveniently produced on the economical model itself’, says Sunil Jain, President, Rajoo Engineers. ‘Anyway, buying a standard Blown Film line is a subject of the past. It is time for you to PICK just the right machine to fit your needs; this revelation from Rajoo, will completely redefine the market dynamics’, adds Sunil.

The Balanced Model is an intelligent hybrid of localised manufacture along with critical components sourced from the collaborators - Hosokawa Alpine, Germany. The natural extension being the Advanced Model, completely sourced from Hosokawa Alpine, Germany, which competes with the best in the world. Balanced and Advanced Models are offered in India, Bangladesh, Nepal, Nigeria, Kenya, Ghana and Tanzania.
The endeavour here is to highlight that features and flexibilities all come at a price. Prudence needs to be exercised by the buyer before he decides; it is important to clearly segregate needs from wants and desires. This is more so important when the quality of the output (your film) is not so affected by the economics of the options available.

While lowering your capital expenditure, the Economical Model will also provide you with the necessary nimbleness to upgrade and adapt to newer technologies with a minimal fuss.

During a recent Open House conducted in India that showcased the Economical and Advanced Models, Rajoo received an overwhelming response from the Indian polymer industry who appreciated this understanding. With the success of this event, Rajoo pays a tribute to its founder and mentor Late Mr. Chandrakant N Doshi.

With K 2013, it is the world which will take cognizance of this highly beneficial approach…looking forward to seeing you at our booth Stand B-58, Hall 15.
