GB/T 6548-2011 "Determination of adhesive strength for corrugated fibreboard" specifies the method for determining the adhesive strength of corrugated fibreboard, which is applicable to various types of corrugated fibreboard. Using a peeling tester, the face paper and core paper, as well as the core paper and inner paper of the corrugated fibreboard are peeled layer by layer, recording the maximum peeling force and calculating the adhesive strength. The standard specifies sample dimensions, temperature and humidity treatment requirements, and controls the testing speed according to regulations. At least five valid data points are required for each bonding surface, and the average value is taken as the result, providing a basis for evaluating the adhesive quality of corrugated fibreboard.
