On August 15, 2025, Guangzhou Sono Scientific Instruments Co., Ltd. welcomed a team of experts led by Director Zhang of the Hunan University Materials Research Institute for a visit and guidance. Accompanied by our General Manager, Mr. Wu, Director Zhang and his team toured the company's exhibition hall, production workshops, and R&D center. The two sides engaged in in-depth discussions on the cutting-edge of materials testing technology and the integration of industry, academia, and research, laying a solid foundation for future cooperation.

At the Guangzhou Sonutra image wall, Mr. Wu introduced the company's development history and vision to the expert team: "For fifteen years, we have consistently adhered to our mission of 'empowering with precision scientific research,' supporting the high-quality development of the global packaging industry and striving to establish the 'Chinese Standard' for global new materials testing." Historical photos on the wall vividly depict Guangzhou Sonutra's journey from technological breakthroughs to industry benchmark.

As the team entered the "Innovation Achievements" exhibition area, the patent wall, illuminated by spotlights, shone like a galaxy of stars. Several national invention patents and utility model patents, along with authoritative certifications such as CMA and ISO9001, forged a technological moat. Professor Zhang commented, "From fundamental theoretical breakthroughs to process implementation, Guangzhou Sonua has established a complete independent R&D system, which is the core driving force behind the transformation of industry, academia, and research."

Afterwards, under the leadership of General Manager Wu, we went deep into the production workshop of Guangzhou Shounuo and guided us to visit the processing area and assembly line. He said: Every instrument and equipment must be tested continuously before leaving the factory to ensure the stability of the instrument.

In the high-barrier laboratory, Mr. Wu demonstrated our core products to Dean Zhang and the professors: water vapor transmission rate testers , gas transmission rate testers , oxygen transmission rate testers , etc., whose testing performance is at the international advanced level. Dean Zhang, the professors and their delegation highly praised our company's demonstrated technical strength.

This exchange was not only a collision of knowledge and experience, but also built a solid bridge for industry-university-research cooperation. Going forward, the company will continue to advance its strategy of "collaboration between universities and enterprises, and resource sharing." Leveraging innovation platforms and guided by market demand, the company will collaborate with universities to overcome key technologies and inject strong momentum into the high-quality development of the packaging industry.
