Another 'Hit Patent' from Dongmin Jang... The Eco-Friendly Technology Partnered with Major Corporations Revealed

Patent for Lightweight PET Bottle Neck Technology

Broadcaster Dongmin Jang has once again obtained a patent for an eco-friendly technology that reduces the amount of plastic used in PET bottle manufacturing. The technology lowers the weight of the bottle's spout while maintaining container strength and sealing performance.Products incorporating this technology have now reached the stage of practical application.

On July 13, Pureunhaneul, an eco-friendly startup led by CEO Dongmin Jang, announced that it has jointly developed the 'Eco Ring' container with Namyang Magic and Dongwon F&B, which features lightweight PET bottle spouts for food and screw spouts for bottled water.

The newly released 'Eco Ring' technology is designed to reduce plastic usage by making the neck structure of PET bottles lighter, without compromising sealing performance or container strength. Each PET bottle can save about 1.5g of plastic, and the technology can be implemented without changing existing production facilities. The company explained that this allows for an increase in production volume of about 10% with the same amount of raw materials.

Jang Dongmin explained, "This technology was jointly developed by the eco-friendly startup Pureunhaneul, container production specialist Namyang Magic, and Dongwon F&B’s packaging development team. With the aim of making PET packaging lighter and more environmentally friendly, we have created a solution that maintains compatibility with existing production systems while enhancing economic viability and sustainability." He added, "The main objective is to use less plastic while maintaining current facilities and increasing environmental value."

The Eco Ring has been applied to and is now sold in select products, including Dongwon Tuna Sauce, olive oil, and canola oil. Monggo Soy Sauce has introduced the technology in certain products and plans to expand its use to all products next month. Trials are also underway to apply the technology to alcoholic beverages such as soju and bottled water PET bottles.

On July 2, Pureunhaneul and Namyang Magic signed a business agreement with Dongwon F&B at the Dongwon Industries Building in Seocho-gu, Seoul, to expand the adoption of eco-friendly containers. The three companies agreed to cooperate on packaging material research and development, including container lightweighting, as well as on environmental campaigns.

Jang Dongmin stated, "The vertical label separation technology is a practical solution that can contribute to solving global environmental issues," and added, "We will devote all efforts to developing technology that allows consumers to easily participate in recycling." Jang Dongmin invented this technology in 2021 and completed its patent registration in 2022. Based on this, he founded the startup 'Pureunhaneul' in 2023.

Previously, Dongmin Jang also developed the 'PET One-Touch Removable Container Label' technology, which automatically separates the label when the PET bottle cap is opened. This technology was patented in 2022 after being filed in 2021, and rights have been secured in nine countries to date.
