This local enterprise in Suqian, founded in 2001, has grown into an invisible industry champion in the PETG battery label segment market.

This national high-tech enterprise specializes in producing PET synthetic chips, PETG heat shrink films for food and beverage, labels, and lithium battery separators. The quality of its PETG double-layer battery labels and PETG polyester synthetic chips has reached international standards; As a supporting supplier for international first-class companies such as Nanfu Battery Co., Ltd., Sichuan Changhong Battery Co., Ltd., Jinbawang (Dongguan) Battery Co., Ltd., and Kebo Group, its products are also exported to more than ten countries including the United States, Germany, Belgium, and Japan.

"When our company was founded, it was a traditional enterprise engaged in printing and packaging. After 20 years of unremitting efforts, it has developed into a national specialized, refined, and innovative 'little giant' enterprise. Over the years, my greatest realization is that as a new materials technology enterprise, we must take the path of 'specialization and refinement'. 'specialization' means deeply cultivating our main business, 'refinement' means mastering new technologies, conducting independent research and development, and mastering technology in our own hands, so that the enterprise can have competitiveness..." Wu Peilong, the general manager of Jinghong New Materials, said with deep emotion that independent research and development is a "key" for them to become industry champions. ".

Independent research and development requires the establishment of one's own research and development team. This high-tech enterprise with 350 employees has over 50 research and development personnel. As early as 2009, Jinghong New Materials and Nanjing University jointly established the "Nanjing University Suqian Advanced Materials Joint Laboratory" and established the "Jiangsu Province Polymer based Nanocomposite Materials Engineering Technology Center", providing strong technical support and guarantee for the subsequent research and development of the company's new products.

Jinghong New Materials has gained more say in the industry due to its willingness to invest in research and technological innovation. Taking the PET battery label, the company's main product, as an example, it includes two key environmental protection technologies: PETG film and high-performance environmentally friendly pressure-sensitive adhesive

ET heat shrink film is a new type of heat shrink packaging material that is easy to recycle, non-toxic, odorless, and has good mechanical properties, meeting environmental requirements; PETG based film is more in line with environmental requirements and the concept of food FDA certification than PET film, and has higher international recognition. But the core technology of PETG is in the hands of American and Korean companies.

Breaking through the blockade of foreign PETG core patents, the R&D team of Jinghong New Materials independently designed a polyester (PETG) synthesis test reactor. Through countless changes in technical parameters and adjustments to the process route, a polyester (PETG) material with good color and superior performance was finally synthesized, and industrialization was successfully achieved. This project has passed the scientific and technological achievement appraisal of the China High tech Industrialization Research Association, and the project technology has reached the international advanced level, filling the gap in China's PETG co polyester industry; This project has also won the Jiangsu Province Excellent New Product Award, Jiangsu Province High tech Product Title, and has been recognized as a national level scientific and technological achievement. At the same time, Jinghong New Materials has also been approved as a key high-tech enterprise under the National Torch Program.

Jinghong New Materials has become the first domestic company to independently develop PETG products, promoting the industrial upgrading of polyester (PETG) films in China and establishing Jinghong New Materials' leading position in the PETG film field.

"In the current field of curved bread covering, most pressure-sensitive adhesives with solvents are still used on the market. Organic solvents are volatile and can cause certain pollution to the environment, which can also affect the health of employees during the production process. The cost of solvent based pressure-sensitive adhesives is also relatively high." Wu Peilong introduced that the R&D team of Jinghong New Materials, based on environmental protection concepts, cost management, technological maturity, and feasibility, consulted a large amount of literature, organized experimental plans, planned experimental schedules, promoted experimental progress, and successfully developed environmentally friendly pressure-sensitive adhesives without organic solvents. This green and environmentally friendly solvent-free adhesive and water-based adhesive greatly reduces production costs and also relieves the company's environmental pressure.

"The company invested nearly 20 million yuan in research and development expenses last year, and has currently obtained 33 authorized patents, with more than 40 being accepted." Wu Peilong introduced that the R&D team actively develops amorphous transparent PETG copolyesters, fully biodegradable polyester materials, flexible low-temperature shrinkage packaging films, green and environmentally friendly polyester catalysts, etc. around the innovative development of packaging materials, further consolidating the market position of the company's products in the fields of food, hygiene, logistics, etc.
