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 [...]

International Packaging Standards Seminar organized by CEPI （China National Export Commodities Packaging Research Institute） was held in Jinan, China on 24th Jan., 2024. Labthink, as the leader in permeation testers, was invited to participate the seminar. The topic of the seminar is ‘National Standards on Green Packaging Evaluation Methods and Criteria’. Experts of packaging industry from International Organization for Standardization （ISO）, Comité Européen de Normalisation (CEN), World Packaging Organization (WPO), Asian Packaging Federation (APF), China [...]

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 [...]

1. Significance Thermal conductive silica gel pad is a kind of thermal conductive medium material, which is based on silica gel and added with metal oxide and other auxiliary materials. This material is filled into the gap between the heat source and the radiator to form a good heat dissipation path between them. Thermal conductive silica gel pad is widely used in LED industry, power industry, communication industry, automotive electronics industry, home appliance industry and [...]
