Scope

GB/T 455-2026 is the English-translated version of 纸和纸板撕裂度的测定.

Tearing resistance describes how well paper or board withstands the propagation of a tear, which matters for wrapping, bags, labels and many printing and packaging grades. This standard covers the determination of tearing resistance of paper and board and is a recommended national standard.

Paper manufacturers, packaging converters, printers, brand owners and testing laboratories can use it to produce comparable results across sites. Product developers who set tear-related requirements in specifications will find it useful as the method behind those requirements.

The 2026 edition was issued on 30 April 2026, takes effect on 1 November 2026 and replaces GB/T 455-2002. Laboratories, mills and customers that cite the earlier edition in their testing procedures or supply agreements should update their references and check their equipment against the revised text before the transition.
