"Our objective was to create a bottle that would reduce material use while maintaining the performance required for efficient production and distribution," said Pavares Kiatsuarpanon, Managing Director at Arpanon. “The final design delivered the combination of lightweighting, strength and operational efficiency we were looking for.”
Meeting the needs for lighter bottle packaging
For its 600ml water format, Arpanon was looking to move beyond its previous bottle specification and achieve a lighter package while supporting reliable production performance. The challenge was to reduce bottle weight without compromising the strength required throughout filling, handling and distribution operations.
Sidel addressed this requirement through a complete packaging optimisation approach. The result was a 25/22 neck PET bottle weighing just nine grams, developed without the need for nitrogen while still achieving more than 30kg of top-load performance. The optimisation reduced bottle weight by approximately 30%, from preform design through bottle development and line optimisation, while maintaining the required performance.
High-speed production enabled by Sidel’s Combi technology
Beyond bottle development, Sidel delivered a complete production solution through its 36,000 bph Combi line, integrating blowing, filling and capping into a single compact system. By engineering both the bottle and production process together, Sidel ensured the new lightweight bottle performs consistently throughout the manufacturing cycle.
The integrated Combi solution provides high quality bottle blowing, stable bottle handling, reliable filling performance and high production efficiency while helping reduce energy consumption, production footprint and operational complexity. As a result, Arpanon doubled production output while using only 25% of its previous labour requirement. Blowing pressure was also reduced by approximately one-third, while electricity consumption per unit was cut by 50%. Production time was reduced by approximately 70%, enabling faster and more efficient operations.
