“Tethered Cap: The Next-Generation Closure for a More Sustainable World.”
Wednesday 26th November 2025, Mr. Opart Dhanvarjor, President together with management and employees of Crown Seal Public Company Limited, officially opened Sustainability Week 2025 under the theme “Tethered Cap: The Next-Generation Closure for a More Sustainable World.”
A key highlight of this year’s event was the introduction of the Tethered Cap, an innovative bottle cap designed to remain attached to the bottle after opening. This design helps prevent cap loss, reduces plastic waste, and allows the cap to be recycled together with the bottle more efficiently. The innovation aligns with the principles of the Circular Economy and promotes responsible resource use throughout the value chain.
The company continues to advance its commitment to ESG principles, recognizing that sustainability is a shared responsibility among everyone in the organization.
