At interpack this week, Sidel presented a 1L PET edible oil bottle produced using laser heating, delivering a 20 per cent weight reduction compared with a halogen-blown equivalent while maintaining comparable overall performance, grip in consumers’ hands and vertical strength for logistics.
The bottle weighs 16.5g, a 4g reduction from the 20.5g halogen version designed to deliver similar performance. PET is concentrated in areas that contribute to mechanical strength and performance, with less material used elsewhere, in what the company describes as a change in design approach enabled by laser heating. It says this precision allows material to be placed where it contributes most to performance.
A central feature is the Power Ring, which acts as a targeted reinforcement, concentrating material to maintain side load performance during opening and pouring. From a logistics perspective, the material distribution is designed to maintain robustness through the supply chain, with top load performance comparable to a heavier halogen alternative. Other areas, including under the neck and at the base, use less material through optimised stretching. The bottle is made from 100 per cent rPET.
Jerome Neveu, packaging and mold product manager at Sidel, said, “This 100 per cent rPET bottle clearly shows how laser precision allows us to rethink packaging design for edible oil. The Power Ring design is a concrete example of mastering exact PET distribution to optimise edible oil packaging while meeting the functional demands of this market.”
The bottle was on show at interpack, where it was displayed alongside a halogen-blown counterpart to allow direct comparison between the 16.5g laser bottle and the 20.5g halogen version. Interactive displays on the stand allow hands-on comparison of weight and resistance.
