Sidel helps to set new packaging standards in India

From innovative concept to functioning industrial design

Throughout the different periods of its development, B.L. Agro approached Sidel to help them differentiate their bottle designs while saving resources and raw material and still being able to address the growing market demand with budget-friendly products. “PET bottles at that time were still a breakthrough in India, attracting end users due to their innovation component and ideally presenting high quality products thanks to their transparency – both very important points for us. When we started working on what became our 2 L and 5 L bottles with handles, Sidel proposed some very creative and disruptive concepts to us. We thus found a design that was quite unique and iconic,” highlights Mr Hada. The result of the thorough packaging development process was the first PET bottle for edible oil with a handle and a triangular design – a novel approach to this type of product. “Producing such a PET bottle with a handle is no easy feat; it was very difficult to find suppliers who were confident to take on this challenge. The packaging team at Sidel was the only one who agreed to do a prototyping of the bottle, including the two notches for the handle,” Mr Khandelwal remembers.

To successfully overcome the twofold challenge, encompassing the PET bottle shape and the handle’s specificity, Sidel’s full set of packaging R&D capabilities was needed, backed up by more than four decades of experience in this segment. “We appreciated the initial design a lot; however, it was quite difficult to see the packaging design become a reality because the bottle is neither square nor round. To add complexity, it also has notches that need to be completely formed, so that the handle insertion can take place. On the other hand, the notches cannot be too deep, because the handle would come off,” explains Mr Khandelwal.

The handle insertion, the orientation of the bottle for the insertion itself, and the definition of the labelling area on the bottle were all issues that the Indian player and Sidel had to solve hand in hand to powerfully differentiate the B.L. Agro packaging options on the retailer shelves. “Together, we were able to take this innovative concept, which offers a real marketing benefit and – via prototyping and extensive testing – turn it into an industrial reality within an operating packaging production line,” says Giulio Bellanti, Sidel Business Development Director for Edible Oil in Asia, Oceania and Africa. 

“We have been very impressed by Sidel’s overall packaging expertise. Additionally, in the second step, we were sure that the proposed designs would also be executed well when it came to blowing the bottles. After all, this is what Sidel is internationally known for. In the end, we achieved an extremely precise blowing combined with exact notch positioning and formations,” adds Mr Khandelwal. 

Award-winning, lightweighted bottles

Besides leveraging the marketing advantage and the brand differentiation, the edible oil company also wanted to significantly lightweight its PET bottles. “Usually, a 2 L bottle with a handle weighs around 70 g. By carefully reviewing the container design, we achieved a weight reduction of approximately 21% and we are processing a 55 g bottle today. The successive lightweighting steps have always been done without compromising the bottle’s top load characteristics and other mechanical requirements for transportation and transit. The bottle’s stability and resistance throughout the supply chain have been tested and validated by Sidel’s packaging experts,” explains Mr Khandelwal. The result is an optimised large format bottle that facilitates the handling, while fully protecting the product inside – a key factor for B.L. Agro’s high quality standards.

Similarly to the 2 L bottle, the 5 L format was also lightweighted – with a reduction from 130 g to 110 g, excluding the handle. These weight reductions have a substantial sustainability impact and translate to more than 650 tons of PET saved per year. These developments also clearly mark significant savings in terms of material costs in a highly competitive edible oil market, particularly in India.

Both bottle formats were successfully introduced to the market and have received national and international recognition by winning the India Star Packaging Award as well as the Asia Star Packaging Award. “We are very pleased with Sidel’s work. Our PET bottles set themselves apart on the shelves and enable an innovative and enjoyable consumer experience around our high-quality, healthy oil,” concludes Mr Khandelwal.
