[E-Daily Starin Gim Ga Yeong Reporter] TV personality Jang Dong-min has developed additional eco-friendly technology and obtained a patent for it. Products incorporating this technology have entered the commercialization phase.

On the 13th, Blue Sky announced, “We have jointly developed the ‘Eco-Ring’ container—a lightweight technology for PET bottle food fillers and screw-top fillers for bottled water—with Namyang Magic and Dongwon F&B.”
The Eco-Ring, which optimizes the spout structure while improving the sealing performance of existing PET bottles and maintaining container strength, offers the following advantages: △ Reduces plastic use by 1.0–2.5 g per unit during the manufacturing process while maintaining container strength, leading to cost savings; △ Complies with the international standard PCO 1810, allowing for implementation without modifying production equipment; △ Enhances container strength and sealing performance △ Improves production efficiency by approximately 10% using the same raw materials; and △ Enhances consumer awareness of eco-friendly products, as consumers can visually identify the Eco-Ring structure.
Jang Dong-min explained, “This technology was jointly developed by the eco-friendly startup Blue Sky, the container manufacturing specialist Namyang Magic, and Dongwon F&B’s Packaging Development Division. With the goal of making PET bottle packaging lighter and more eco-friendly, we developed a solution that enhances economic efficiency and sustainability while maintaining compatibility with existing production systems.” He added, “The main objective is to use less plastic and increase environmental value while retaining existing equipment.”
Blue Sky and Namyang Magic signed a business agreement with Dongwon F&B on the 2nd at the Dongwon Industry Building in Seocho-gu, Seoul, to promote the widespread adoption of eco-friendly containers. This agreement was initiated to expand the use of eco-friendly containers, reduce plastic consumption, and practice ESG management, leveraging the technological capabilities and expertise of each company. The companies agreed to collaborate on research and development for sustainable packaging materials, such as lighter containers, and to jointly launch eco-friendly campaigns.
Jang Ho-jeong, Team Leader of the Packaging Development Division at Dongwon F&B, said, “We are applying eco-friendly packaging materials to a variety of products, including liquid products, Yangban Kim, and gift sets, and we plan to introduce them to an even wider range of products through continuous R&D.”
Jang Dong-min added, “We have already applied this to containers for Dongwon Tuna Juice, olive oil, and premium canola oil, which are currently on the market, and after completing partial implementation for Monggo Soy Sauce, we plan to expand the launch to all items next month.” He continued, “We will take the lead in realizing a resource-circulating society through eco-friendly solutions that allow us to achieve both environmental protection and cost reduction.”
