This bottle illustrates a fundamental change in the design approach made possible by laser heating. PET is intentionally concentrated only where it contributes to mechanical performance, while unnecessary material is removed elsewhere. This precision allows material to be placed where it contributes most to mechanical performance.
The result is a 1L edible oil bottle weighing just 16.5g, a 4g PET saving when compared with its equivalent in halogen, which would weigh 20.5g to deliver similar performance. By reinforcing critical stress areas and avoiding unnecessary material use, this design shows how lightweighting can be extended when strength is added with purpose and not by default.
In this bottle, the Power Ring design plays a central role in consumer handling. Acting as a targeted reinforcement, it concentrates material exactly where needed to maintain side load performance during opening and pouring. From a logistics perspective, the overall material distribution ensures the bottle remains robust throughout the supply chain with a secured top load performance comparable to a heavier halogen alternative. At the same time, other areas of the container, including zones such as under the neck or on the bottle base, feature optimised stretching and a lower quantity of material.
