Target

The goal of this project was to push the absolute limits of lightweighting and resource efficiency in the beverage industry and create the lightest 0.5-liter PET container. Also, to make it even more sustainable, the bottle had to be made utilizing 100% recycled PET (rPET).

Result

  • SIPA achieved a breakthrough that sets a new industry standard for single-serve water bottles.

    • Extreme Lightweighting: Successfully developed a 0.5-liter bottle weighing only 4.95 grams.
    • Material Success: The bottle is manufactured entirely from 100% rPET, achieving a fully circular material loop.
    • Production Versatility: The design uses a 25/22 neck finish, making it compatible with the full range of SIPA Xtra rotary blowmolding machines (6 to 24 cavities).
    • Integrated Manufacturing: The bottle is optimized for the SIPA SINCRO TRIBLOC, a synchronized system that handles blowing, labeling, filling, and capping in a single compact unit.

Advantages 

This innovation represents a paradigm shift in how PET packaging is produced and perceived.

  • Significant Carbon Footprint Reduction: By combining 100% recycled material with a massive reduction in plastic mass, the total environmental impact is minimized more than ever before.
  • Energy Efficiency: A major technological advantage is the exceptionally low blowing pressure (18 bar or less) required. This leads to lower energy consumption and reduced operational costs for manufacturers.
  • Scalability: Despite its delicate weight, the bottle is designed for high-speed, large-scale production, ensuring it can meet global market demands.
  • Space & Process Optimization: Through the SINCRO TRIBLOC integration, the production process is streamlined, reducing the physical footprint of the factory and maximizing output efficiency.
