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 [...]

Moisture proof package is for protection against moisture during logistics. Moisture proof package is widely used in machinery, electronics, foodstuff, medicine and daily care, etc. It is a most commonly used protection against moisture during logistics. Moisture proof package avoids rusts and deterioration of the packed contents effectively. Labthink, as the excellent provider of testing instruments and testing services, integrates moisture proof methods with relevant methods for introduction. The moisture proof packages are tested according [...]

WVTR is the abbreviation for water vapor transmission rate, which is defined as the constant rate at which water vapor permeates through a specimen film at specified conditions of temperature and relative humidity.

Water Vapor Permeation Test System is applicable in water vapor permeation test for plastic films, laminated films, sheets, solar energy back sheets, high barrier materials, foils, OLED, water-proof membranes and bottles, pouches, jars, boxes made of plastic, rubber, paper, glass and metal, as well as medical devices, etc. With water vapor permeation testing, controlling and adjustment of packaging materials can be achieved; application demands can also be satisfied. Water Vapor Permeation Test System conforms to [...]

Mositure Barrier of IV bag is the most important factor affecting the quality. Owing to the low barrier property of the content contact package, a barrier package is needed for prevention of moisture & oxygen permeation. Besides, nitrogen is applied to take place of the air between the inner package and barrier package. Therefore, oxygen transmission as well as nitrogen and moisture transmission should be tested. Labthink VAC-V series of differential pressure gas permeation testers can accomplish [...]

The research on encapsulation material of FOLED (flexible organic light emitting diodes) has been a focus of FOLED research both at home and aboard. How to measure water vapor transmission rate , oxygen and other active gases through FOLED  material is one of the important subjects for FOLED encapsulation.  Labthink Instruments Co., Ltd. , as the world renowned testing instrument and testing service provider, introduces the professional FOLED encapsulation material water vapor and gas transmission testing [...]

Moisture Barrier Testing of BOPP Film High moisture barrier performance is a must for flexible package so as to avoid deterioration caused by moisture. At present, this factor is not fully noticed by the flexible packaging manufacturers. Labthink PERME W3/030 is developed according to ASTM E96, ISO 2528 and other standards to test moisture transmission rate for materials. The lower WVTR the better. But, higher barrier property means more costs. Therefore, the common data is less than 10g/m2.day or 5g/m2.day. BOPP [...]

Water Vapor Permeation Testing of Solar Cell Backsheet Film plays the most important role on the quality control of solar cells. The backsheet can protect the photovoltaic components, like solar panel. The main quality of the backsheet is determined by its water vapor barrier property. If the backsheet can not block the water vapor in the air, the vapor will enter and break the bonding force between EVA layer and the panel. When the water vapor contact with solar panel directly, the solar panel will be oxidated and lose its function of generating current.
