offline
This standard practice describes a creasing procedure for tests requiring creased specimens of flexible
packaging materials made of paper or paper-based materials. In most instances, it is advantageous to compare the
results of the creased specimens with those of uncreased specimens. This standard practice is not applicable to board
grades (those exceeding 0.25 mm [0.01 in.] in thickness).
