Labthink Instruments Co., Ltd. info@labthink.com +86-531-85068566 Testing Moisture Barrier Properties of Aluminum Plastic Composite Film for Ensuring Pharmaceutical Protection Keywords: Aluminum plastic composite (APC) film, Moisture barrier property, Water vapor transmission rate (WVTR), Water vapor permeability (WVP), Flex durability test (ASTM F392), Labthink, C681M Flex Durability Tester, Water vapor transmission rate test, Labthink C360M Water Vapor Transmission Rate Tester, Gravimetric method (cup method) Aluminum plastic composite film (APCF) is a popular choice for pharmaceutical packaging due to its excellent barrier properties against moisture and oxygen. This helps extend the shelf life and maintain the quality of sensitive medications. However, the film's effectiveness can be compromised during various stages like forming, filling, sealing, and transportation. This article discusses the importance of testing the moisture barrier property of APC film after simulating these stresses.

Labthink Instruments Co., Ltd. info@labthink.com +86-531-85068566 APCF typically consists of layers of plastic film bonded to a central aluminum layer. The aluminum acts as the primary barrier against moisture vapor transmission (MVTR). However, flexing the film during processing can create pinholes or weaknesses in the aluminum layer, allowing moisture to penetrate and potentially degrade the pharmaceuticals. To ensure the integrity of the moisture barrier, manufacturers and users perform water vapor permeability (WVP) tests on APC film samples. These tests are conducted after subjecting...

The instrument automatically conducts the test and provides the final WVP result. By measuring the WVP after the flex durability test, manufacturers and users can evaluate the effectiveness of the APC film in maintaining its moisture barrier properties under real-world stresses; ensure the film meets the WVP requirements for specific pharmaceutical packaging applications; and identify any potential weaknesses in the film's...
