In the packaging industry, ensuring the barrier properties of materials against moisture is crucial. The ability of a material to resist water vapor transmission significantly impacts the shelf life, quality, and performance of packaged products. This is especially important in industries such as food, pharmaceuticals, electronics, and cosmetics, where even minimal exposure to moisture can compromise the product. This is where water vapor permeability testers play a vital role. Choosing the best water vapor permeability [...]

Labthink C360M Water Vapor Permeability Tester is a high-precision instrument designed for testing the water vapor transmission rate (WVTR) of materials, including packaging films, textiles, and coatings. It operates based on the Gravimetric Method, allowing for accurate measurement of the rate at which water vapor passes through a material. C360M tester is widely used in industries such as food packaging, pharmaceuticals, and textiles to evaluate materials’ moisture barrier properties. It helps determine the water vapor [...]

Testing Water Vapor Transmission Rate (WVTR) in films is a critical process for determining how well a material—such as plastic films, packaging materials, or protective coatings—resists the passage of water vapor. This property is essential for industries such as food packaging, pharmaceuticals, textiles, and electronics, where moisture control is vital for product preservation and quality. Here’s a step-by-step guide on how to test Water Vapor Transmission in films: Methods for Testing Water Vapor Transmission in [...]

Abstract: The primary application of hydrogel in the medical field is the wound dressing. As the closest biological functional material to living tissues, hydrogel can make direct contact with human tissues, prevent external microbial infection, effectively prevent the loss of body fluids, and transmit oxygen and promote wound healing. At the same time, as a drug release carrier, because of its good permeability to low molecular solutes, it also gives the function of hydrogel drug [...]

The pharmaceuticals are easily deliquesced after absorbing moisture, for which the packaging materials should be of high moisture barrier property. Aluminum plastic composite film is widely used in pharmaceutical packaging which can help extend the shelf life and guarantee the quality of the pharmaceuticals. However, the aluminum layer may be folded during package forming, product filling, heat sealing and transportation processes and as a result the barrier property (both oxygen barrier property and water vapor [...]

Never mind thinking outside the box-we’ve put everything in the box! OTR-WVTR Automatic/Sequential testing in a single tester for the first time worldwide! Labthink 406H Oxygen /Water Vapor Transmission Rate Test System is innovative instrument that is integerated OTR and WVTR in one tester based on the testing principle of Coulometric oxygen sensor and infrared water vapor sensor. It is designed and manufactured according to ASTM D3985、ASTM F1249，ISO 15106-2 and other relevant standards to provide [...]

Now, the war against the COVID-19 has reached the critical stage. 42000 medical staff have come to Hubei from all provinces and cities brought hope to the land of Jingchu. Medical protective clothing is their “battle armor”. In hospitals and laboratories with the most dangerous epidemic situation, these “medical practitioners” wear thick protective clothing and fight on the front line of the epidemic. Dr. Zhou experienced protective clothing for the first time “A lot of [...]

in this paper, the moisture permeability test method of drug packaging materials is introduced in detail according to YBB00092003 standard. The correlation between data from various test methods, the correlation between dry cup method and wet cup method, and the future development direction are described.

In early 2020, a novel coronavirus outbreak was identified by experts. Because there is no wonder drug at the moment, it has caused an alert at the beginning. Experts suggest that the public should stay at home to prevent virus transmission; when going out is necessary, wear a mask for self- protection. As the continuous of the epidemic, the demand for medical protective equipment has increased dramatically, resulting in insufficient supply and shortage. At the [...]
