Foreword
This standard replaces GB/T 6544-1999 “Corrugated fiberboard”, GB/T 16718-
1996 “Packing material - Heavy duty corrugated fiberboard” and GB/T 5034-

the main changes of this standard are as follows.
- USE the normative reference instead of reference standards. DELETE
GB/T 6548 “Determination of ply adhesive strength for corrugated
fiberboard”. DELETE GB/T 4857.2-1992 “Packaging - Transport packages
- Temperature and humidity conditioning”. DELETE GB/T 16717-1996
“Packing containers - Heavy duty corrugated box” (clause 2 of the 1999

requirements for the index (Table 1 of clause 4 of the 1999 version; clause
5 of the 1996 version; clause 2 of the 1985 version; Table 1 of clause 4 of
this version);
- ADD the structure and symbolic representation of the corrugation type of
the corrugated fiberboard, both the number of corrugations and the width
index of corrugation (Table 2 in clause 4 of the 1999 version; clause 5 of
the 1996 version; clause 2 of the 1985 version; Figure 1 and Table 2 of this
version);
- MODIFY the requirements for the ply adhesive strength of corrugated
fiberboard (clause 5 of the 1999 version; clause 2 of the 1985 version;

- MODIFY the appearance requirements of corrugated fiberboard (clause 5
of the 1999 version; clause 5 of the 1996 version; clause 2 of the 1985
version; clause 5 of this version);
- MODIFY the test method for ply adhesive strength (clause 6 of the 1999
version; clause 2 of the 1985 version; clause 6 and Appendix B of this
version);
- ADD the test method for maximum warpage (clause 6 of the 1999 version;
