GB/T 34444-2017 《Paper and board—Determination of the layer peel strength》 Related products

GB/T 34444-2017 "Determination of peel strength between layers of paper and Cardboard" standard specifies the test method for measuring the peel strength between layers of paper and Cardboard. It is suitable for coated paper, composite paper and Cardboard with a thickness greater than 0.5 mm, but not for corrugated fibreboard. The standard details the test principle, required instrumentation, and requirements for chuck displacement and data processing during the test process. Through this standard, the interlayer peel strength of paper and Cardboard can be accurately determined, helping to improve the quality control and performance evaluation of related products. This standard has important guiding significance for enterprises that produce and test coated paper and composite paper products.
