Juwei Can Manufacturing unveils new products; tinplate cans may become a “blue ocean” opportunity for small‑packaging edible oils in China.

On May 8, nearly 50 leading domestic experts and representatives from prominent oil‑and‑fat companies gathered in Qihe, Shandong, to attend the product launch event of Shandong Juwei Can‑Making Co., Ltd. They shared insights on Juwei’s newly developed “tinplate edible‑oil can” and explored new avenues for technological advancement in the oil‑and‑fat packaging industry. Among the attendees were Professor Wang Ruiyuan, a chief expert on advisory and decision‑making at the China Association for Science and Technology; He Dongping, president of the Oil and Fat Branch of the China Cereals and Oils Society and a professor at Wuhan Polytechnic University; Researcher Zhang Yixin, vice president and secretary‑general of the same branch; and Researcher Xiang Hai, also a vice president of the branch. Representatives from enterprises including Yihai Kerry, Luhua Group, Jinsheng Grain & Oil, and Qingdao Changshou Food also took part. The event was chaired by Miao Yongjun, a senior engineer and member of the Oil and Fat Branch of the China Cereals and Oils Society, as well as a senior researcher at the Hunan Provincial Academy of Forestry Sciences.

Smart design addresses the longstanding pain points of traditional tinplate packaging for edible oils.
After two years of research and development, Shandong Juwei Can Manufacturing has launched a next‑generation tinplate can that delivers smoother oil pouring and superior freshness retention. Through intelligent design, it addresses longstanding pain points of traditional edible‑oil tinplate packaging—such as inconvenient opening, poor pourability, difficulty in preventing backflow at the spout, incomplete dispensing, and residual contamination on the can body—offering the edible‑oil industry a new storage solution while providing consumers with a fresh, improved pouring experience.
Xu Dequan, a member of the Party Leadership Group of the Dezhou Municipal Development and Reform Commission and Director of the Municipal Food Security and Assurance Center, stated in his address that Juwei Can Manufacturing, a company with 20 years of experience in producing high‑end iron cans for edible oil packaging, boasts sophisticated technology and robust capabilities. Upholding a craftsman’s spirit of relentless pursuit of excellence, the company has achieved notable success in technological innovation, product upgrades, and market expansion, with its Dongguan and Qihe plants generating annual sales exceeding RMB 200 million. The newly launched tinplate packaging cans for edible oil not only showcase the company’s strong innovative capacity but also reflect its keen insight into market needs and its commitment to producing quality products with integrity.

In his address, He Dongping pointed out that China is a major producer and consumer of edible vegetable oil, with annual consumption exceeding 40 million tons. However, the country’s self-sufficiency rate remains low, leaving a significant supply gap. Consequently, reducing post‑harvest losses of edible vegetable oil and ensuring the safety and quality of stored oil are of paramount importance. As the primary container for storing edible oils, packaging plays a critical role in safeguarding public health. The recent promotion of Juwei Can’s tinplate edible‑oil cans represents an effective industry‑driven initiative—guided by market demand and anchored in technological innovation—that will help shift edible‑oil packaging from a function‑oriented approach to one focused on quality.

Li Yonghui, General Manager of Shandong Juwei Can‑Making Co., Ltd., stated that the company operates large dust‑free production workshops and more than ten fully automated production lines, with a monthly output exceeding 3 million cans. Backed by state-of-the-art equipment, strong technical expertise, and rigorous quality‑control measures, the company has obtained certifications including the “National Industrial Product Production License” and the “ISO 22000 Food Safety Management System Certification.” Furthermore, its tinplate packaging cans for edible oils—available in various specifications—have all received favorable test reports from the National Key Laboratory for Testing Food Contact Materials. The company currently holds 17 national patents, covering inventions, utility models, and designs.
At the scene, a reporter from the Grain and Oil Market newspaper observed that Li Yonghui’s presentation of the new product brought the press conference to a thrilling climax. He provided a clear, hands-on demonstration comparing Juwei’s innovative tinplate edible‑oil can—featuring a pull‑tab lid, easy pouring, a twist‑off cap, minimal residual oil on the can walls, and superior compression resistance—to conventional metal cans. The demonstration not only won over the attendees but also drew Wang Ruiyuan and He Dongping onto the stage to examine the product up close and operate it themselves.
Wang Ruiyuan stated that after seeing Juwei Can Manufacturing’s new “tinplate edible‑oil can,” he was truly impressed, as it thoroughly addresses many of the issues inherent in traditional products and offers the same ease and convenience as small‑packaging containers made of plastic or glass.
Tinplate cans are poised to become the new favorite for small‑size edible oil packaging.
As living standards rise, consumer expectations for edible oils have grown increasingly sophisticated, shifting from “eating whenever one wants” to prioritizing “food safety” and “good nutrition.” On January 9, the National Food and Strategic Reserves Administration held a press briefing, advocating the principle of “use less oil, choose better oil, and enjoy better health,” while noting that future edible‑oil packaging will trend toward smaller sizes and greater ease of storage. Smaller portions and opaque metal containers are key measures for safeguarding the quality of oil products.
During the guest‑forum session, Liu Yulan, deputy head of the Expert Group of the Oils and Fats Branch of the China Cereals and Oils Association and a professor at Henan University of Technology, delivered a presentation titled “Advances in Low‑Temperature Preservation of Stored Oils and in Edible Oil Packaging Technologies.” She noted that, in the new era of consumption upgrading, ensuring consumers’ high‑quality experiences and positive perceptions of edible vegetable oils—from production through packaging, storage, distribution, and finally to the dining table—requires maintaining consistent product quality across the entire supply chain. This also places higher demands on packaging materials and containers, necessitating stringent measures to prevent the migration of phthalate plasticizers, heavy metals, and other contaminants into edible vegetable oils. The focus is shifting from mere shelf‑life extension to true freshness preservation, with the goal of safeguarding quality, nutrition, and flavor.
“Whether it is bulk‑packaged or pre‑packaged edible oil, proper storage plays a crucial role in maintaining product quality and shelf life,” says Liu Yulan. She notes that tinplate cans used for packaging edible vegetable oils offer several advantages: excellent corrosion resistance, non‑toxicity, high strength, and good ductility; they also pose minimal safety risks associated with plasticizers, exhibit low oxygen permeability, and provide effective light‑proofing, thereby enhancing the preservation of oil quality and freshness. Nevertheless, storing oil at low temperatures remains equally important.

Notably, according to experts—including Wang Ruiyuan, Jin Qingzhe, head of the expert panel of the Oils and Fats Branch of the China Cereals and Oils Association and a professor at Jiangnan University, and Liu Guoqin, deputy head of the same panel and a professor at South China University of Technology—as well as industry representatives, rising consumer concern over food safety is likely to make tinplate cans the mainstream choice for small‑size edible oil packaging. They also advised Juwei Can Manufacturing to reduce costs, ramp up marketing efforts, and shift its R&D focus toward smaller package sizes ranging from 500 mL to 1 L.

During the conference, the delegates also paid a keen visit to Juwei Can Manufacturing’s factory premises, where they highly commended the company’s philosophy and practices of “producing conscientious products as a conscientious enterprise.”
