Sidel is announcing the presentation of a 1-litre PET bottle for edible oils produced in a stretch blow moulding process using laser heating. The manufacturer states that the solution is intended to combine weight reduction with comparable overall in-use performance, hand grip comfort and resistance to vertical loads relevant to logistics. A key element of the design is the Power Ring structure, which is intended to enable targeted reinforcement of selected zones of the packaging. According to the company, this change results from a different design approach enabled by the precision of laser heating, focusing material in areas critical to mechanical performance and reducing material in other sections.
In practice, this is intended to translate into a bottle weighing 16.5 g, which means a saving of 4 g of PET compared with an equivalent made using halogen blow moulding, which according to Sidel weighs 20.5 g. The company reports that the laser bottle is 20% lighter than the halogen version while maintaining similar functional characteristics. The statement emphasises that the weight reduction was achieved by reinforcing critical areas exposed to loads and limiting unnecessary material use in locations less important from a strength perspective.
The role of the Power Ring structure is intended to be particularly apparent during consumer use stages such as opening and pouring. According to Sidel, targeted reinforcement concentrates material in zones responsible for resistance to lateral loads. From a supply chain perspective, such material distribution is intended to ensure strength during transport and warehousing and top-load resistance comparable to the heavier alternative produced with halogen technology. At the same time, in other parts of the container, including under the neck and in the base area, optimised stretching and a reduced amount of material were applied.
Commenting on the solution, Jerome Neveu, Packaging and Moulds Manager at Sidel, said: "This bottle made from 100% rPET clearly shows how the precision of laser technology enables us to take a new approach to designing packaging for edible oils". He also added: "The Power Ring concept is a concrete example of mastering precise PET distribution, which translates into optimising edible oil packaging while taking into account the functional requirements of this market."
The official presentation of the bottle is scheduled to take place at interpack 2026 at the Sidel stand (Hall 13, Stand B47). The manufacturer says the laser blow-moulded Power Ring bottle will be displayed alongside its halogen blow-moulded counterpart, enabling a direct comparison of 16.5 g versus 20.5 g. According to the announcement, the stand will also feature interactive exhibits allowing a hands-on comparison of the weight and strength of both variants.
