Water Vapor Permeability Tester for Pharmaceutical Packaging-1

Moisture Barrier Properties Analysis for Aluminized Composite Film in Pharmaceutical Packaging Abstract: Aluminized composite film is a common barrier material for pharmaceutical packaging. Based on the principle of electrolytic sensor, this paper tests the water vapor transmission rate of three kinds of aluminized composite film samples for pharmaceutical packaging, compares their moisture barrier performance, and introduces the test principle, equipment parameters, applicable scope, test process, etc., which provides a reference for the test of water vapor transmittance of aluminized composite film samples. Keywords: aluminized composite film, medicine, packaging material, water vapor transmission, electrolytic sensor method, water vapor transmission rate test system, moisture barrier performance There are many kinds of packaging materials for drugs, such as plastic bottles, aluminum foil, hard film, aluminum plating composite film, CO extrusion composite film, etc. these materials should have high barrier performance, which can prevent the drugs from discoloration, deterioration, moisture absorption, caking and other quality problems. The barrier performance of drug packaging materials includes the barrier of oxygen, nitrogen, water vapor and other gases, such as preventing the excessive permeation of oxygen and water vapor in the environment into the inside of the package, lowering the nitrogen content in the package. Due to the different types of packaging materials, their barrier properties are different. For the aluminum plating composite film, due to the existence of aluminum plating layer, the barrier properties of this kind of materials are not only related to the material composition of plastic polymer materials, but also related to the aluminum plating process. In this paper, through the test of water vapor transmission rate of aluminized composite film for drug packaging, the difference of moisture barrier performance of this kind of material is compared. 2、Sample In this test, the water vapor transmission rate of three kinds of aluminized composite films of packaged drugs were tested, the samples were numbered with 1#, 2# and 3#. 3、Standard The test principle of water vapor transmittance includes cup method, infrared sensor method

(1) Cut one specimen from each of the three samples. (2) Mount the specimens in three test chambers of the instrument and close tightly the upper chamber cover. (3) Set the sample name, thickness, test temperature, humidity, test mode and other parameters in the control software, and click the “test’ button to start the test. The instrument runs according to the set parameters, and displays the test results after the test. 6、Test results The water vapor transmission rate of 1#, 2# and 3# composite film samples we0.071 g/(m2·d), 0.234 g/(m2·d) and 0.248 g/(m2·d) respectively. 7、Conclusion In this...
