It offers a comprehensive WVTR testing solution to ensure the barrier properties and safety of product packaging. -
Time：14.10.2025In the pharmaceutical industry, drug quality and safety are paramount. The performance of packaging materials (pharmaceutical packaging materials) that come into direct contact with drugs directly impacts their stability, effectiveness, and safety. Barrier properties are a key performance indicator for pharmaceutical packaging materials, determining their ability to effectively resist the intrusion of gases like water vapor and oxygen, while preventing the loss of active ingredients. -
Time：29.09.2025In packaging for food, pharmaceuticals, electronics, and medical devices, the oxygen barrier performance of materials directly affects product shelf life, safety, and functionality. The Oxygen Permeability Tester (also known as OTR Tester) is a critical instrument for evaluating this performance, providing key data for material development, quality control, and packaging design. -
Time：28.09.2025Explore the core principles and applications of Gas Transmission Rate Testers (also known as Gas Permeability Testers). Learn how precise measurement of oxygen, carbon dioxide, and other gas transmission rates ensures quality and safety in food, pharmaceutical, and packaging industries. -
Time：27.09.2025Barrier properties are crucial in packaging, food, pharmaceuticals, electronics, and advanced materials. Water vapor transmission rate ( WVTR ) testers (often called moisture permeation meters ) are key instruments for measuring a material's moisture resistance. Many companies are confused when choosing between the two dominant methods: the cupping method and the infrared method. This article will delve into the principles, advantages, and disadvantages of these two technologies to help you make the most informed investment decision. -
Time：25.09.2025Various organic solvents are used in the production process of pharmaceutical packaging materials, such as toluene and xylene in printing inks, and ethyl acetate and acetone in composite processes. Gas chromatography, with its high separation efficiency and high sensitivity, can accurately detect extremely low levels of residual solvents, promptly identifying these invisible safety hazards.
