On September 11, 2025, Yang Ming, Deputy Secretary-General of the Electronics Committee of the China Packaging Federation, visited Guangzhou Solutia Scientific Instrument Co., Ltd. As a professional manufacturer of flexible packaging testing instruments, Guangzhou Solutia showcased its technological innovations in the field of flexible packaging quality testing.

Accompanied by General Manager Wu, Deputy Secretary-General Yang Ming toured our R&D center, laboratory exhibition hall, and production workshop, gaining detailed insights into the technical features and applications of core products such as gas permeability testers, oxygen permeability testers, water vapor permeability testers, gas chromatographs, and tensile testing machines. He expressed appreciation for Guangzhou Solutia's commitment to independent R&D and innovation, resulting in numerous national patents and honors, and particularly recognized its contributions to promoting quality testing standardization in the flexible packaging industry.

A water vapor transmission rate (WVTR) tester is an instrument used to accurately measure the rate at which water vapor (moisture) penetrates packaging materials or container walls. Its core function is to quantitatively assess the moisture or humidity barrier properties of packaging materials, a key quality control tool for protecting products from moisture, maintaining product quality, and extending shelf life.

An oxygen transmission rate tester is an instrument used to accurately measure the rate at which oxygen penetrates packaging materials or container walls. Its core function is to evaluate the barrier properties of packaging materials—that is, their ability to prevent the passage of oxygen. This is crucial for protecting sensitive products such as food and electronics.

Packaging materials (such as plastics, inks, adhesives, and coatings) may contain residual chemicals during the production process. Gas chromatographs can accurately detect these substances to ensure they do not pose a risk to human health or affect product quality.

Deeply cultivate the field of packaging testing and create a quality benchmark

Since its founding, Guangzhou Sono Scientific Instruments Co., Ltd. has focused on the research, development, and manufacturing of packaging testing instruments, establishing itself as a leading company in the domestic flexible packaging testing field. Leveraging over 15 years of technological expertise and innovative practices, we have secured numerous national patents and software copyrights. We not only provide reliable testing solutions for renowned companies such as Master Kong, Nestlé, and Liby, but also export our products to overseas markets, including Europe, the US, and Southeast Asia.
