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.
