GB/T 6982-2003 "Test Method for Water Vapor Permeability of Flexible Packaging Containers" specifies the test method for water vapor permeability of flexible packaging containers such as plastic bags and composite film bags. Under specified temperature and humidity conditions, a water vapor pressure difference is created between the inside and outside of the sample container. By measuring the amount of water vapor that permeates into the desiccant or permeates out into the dry carrier gas, the water vapor permeability is calculated, which serves as a key indicator for evaluating the moisture resistance of flexible packaging.
