Test methods for water vapor transmission of rigid containers

GB/T 6981-2003 "Test Method for Water Vapor Permeability of Rigid Packaging Containers" specifies the test method for determining the rate at which water vapor passes through the container wall and seal into a dry internal space under specific temperature and humidity conditions for rigid packaging containers such as glass bottles and metal cans. By measuring the weight of water vapor that permeates into the container over a specified period, the water vapor permeability is calculated to evaluate the container's moisture-proof and sealing performance.
