Two invention patents of Shijiazhuang Sihua Pharmaceutical Group’s Bosheng Medical Devices have been awarded the Jiangsu Province Outstanding Invention Patent Award and the Taizhou City Top Ten Employee Invention Patents, respectively.

Recently, two patents—“Disposable Biomembrane and Its Preparation Method and Applications” and “A Novel Coated Pharmaceutical Vial Stopper and Its Manufacturing Method”—owned by Jiangsu Bosheng Medical New Materials Co., Ltd., a subsidiary of Shijiazhuang Sihua Pharmaceutical Group, were recognized by the Jiangsu Provincial Federation of Trade Unions and the Taizhou Municipal Federation of Trade Unions as the Jiangsu Provincial Outstanding Invention Patent and one of the Top Ten Invention Patents by Employees in Taizhou, respectively.

The invention patent “Disposable Biomembrane, Its Preparation Method, and Applications” focuses on advancing core technologies in key areas of the production and application of disposable biomembranes, thereby enhancing the material’s performance in barrier properties, tensile strength, chemical compatibility, and low leachability. This project has been awarded the First Prize for Technological Application Achievements by Xinghua City’s Employees’ Association and was also recognized as one of Taizhou City’s Top Ten Invention Patents by its Employees’ Association. In recent years, Bosun Medical Materials has not only intensified research on critical common and cutting-edge technologies but has also taken the lead in China in establishing a multi-layer co-extruded biomembrane production line for single-use systems (SUS), significantly boosting the mass production capacity of disposable biomembranes and effectively meeting market demand.

The invention patent entitled “A Novel Coated Pharmaceutical Stopper and Its Manufacturing Method” aims to address the shortcomings of existing manufacturing processes for barrier pharmaceutical stoppers and the associated issues of drug compatibility. By employing a self-developed vacuum vapor-deposition coating technology, the invention offers advantages such as process stability, consistent product quality, energy efficiency, and environmental friendliness, thereby endowing the novel coated rubber stopper with outstanding barrier properties, excellent drug compatibility, silicon-free characteristics, and stable chemical performance.

As one of the leading enterprises in China’s pharmaceutical packaging materials industry, Bosheng Medical Materials has, in recent years, made innovation-driven development its core strategy, focusing on the R&D and manufacturing of novel pharmaceutical packaging materials. The company fully leverages the advantages of its collaborative “industry–university–research–application” innovation mechanism to achieve breakthroughs in key technological areas within the pharmaceutical packaging and drug industries. By actively benchmarking against international best practices, several technical standards and analytical methods co-drafted by Bosheng have been incorporated into the 2025 edition of the Chinese Pharmacopoeia. Throughout its ongoing efforts to upgrade technology and develop new products, Bosheng has continuously expanded its product portfolio, including pharmaceutical rubber stoppers and medical infusion films, with internal quality control standards that exceed national industry requirements. This underscores the company’s robust technological innovation capabilities and its leading position in the pharmaceutical packaging materials sector.

“The simultaneous recognition of these two patents by the provincial and municipal federations of trade unions is not only an affirmation of Bosun Medical Devices’ sustained innovation capability, but also a significant boost to the innovative enthusiasm of our employees,” said the company’s head. “We will remain problem-oriented, continue to leverage our organizational strengths, bring together talent with diverse technical and professional skills, fully unleash the innovative and creative vitality of our workforce, and inject strong technological momentum into the Group’s high-quality development.”
