Unlock the Future: Trends and Technologies in Cap & Closure

Jun Mon 2025

On May 26, 2025, PTT Global Chemical Public Company Limited (GC) organized an online seminar titled “Unlock the Future: Trends and Technologies in Cap & Closure.”
The seminar aimed to educate and strengthen understanding among customers, partners, and plastic resin manufacturers regarding the overall trends in soft drink packaging, innovations, and technologies from Cap & Closure manufacturers, as well as GC’s product offerings that meet consumer needs. The goal was to help stakeholders prepare for and adapt to ensure sustainable competitiveness in the global market. The event received significant attention from participants across various industries.

The seminar featured expert insights from Richard Novemeskey and Jean Janella Ang of Coca-Cola, who spoke about sustainability, describing it as a core part of the company’s DNA. Their focus areas included:

  • Water management
  • Packaging innovation
  • Emission reduction

Key Packaging Development Trends highlighted included:

  • Lightweighting
  • Neck finish diameter reduction
  • Smaller pack sizes
  • Top print to emboss transition
  • Recyclability
  • Colorless closures
  • Use of recycled content
  • Refillable plastic bottles
  • Tethered closures

Coca-Cola also shared its vision for the next decade, aiming to use 35–40% recycled plastic content in its packaging materials.

Additionally, Alessandro Falzoni from Sacmi presented on innovations and technologies in Cap & Closure manufacturing. He emphasized the trend in water closures that has led to a 70% reduction in weight. The best-selling closure currently weighs only 1.8 grams and achieves a cycle time of 2 seconds. Sacmi continues to innovate by developing lighter closures while improving production cycle efficiency.
