Application Summary AI generated
GB/T 31905-2015 specifies a test method for measuring the rate at which liquids penetrate the cut edges of paper and board. It is applied in quality control and material selection for packaging, particularly where edge sealing or liquid resistance is critical, such as in food containers, beverage cartons, or industrial packaging. The standard ensures consistent evaluation of edge permeance to prevent leakage or structural failure during storage and transport.
