Label-free PET bottles and improved transportation efficiency
Published: September 2026

Collaboration Outcomes
The 460ml PET bottle for “Oi Ocha Green Tea,” jointly developed by ITO EN and Toyo Seikan, received the “Packaging Technology Award – Logistics Award” at the 2024 Japan Packaging Contest organized by the Japan Packaging Institute, as well as the “AsiaStar Consumer Package” category award at AsiaStar 2024 organized by the Asian Packaging Federation.
Based on the concept of “slim and easy to hold = smart slim,” the bottle was developed as a convenient, portable container. Its smart slim shape improves loading efficiency during transportation, while embossing the product name enables a label-free design and reduces plastic use.
