Z-Direction Tensile

This test uses double-stick tape to attach the sample to anvils in a test instrument. The anvils are then separated while measuring the maximum force required to delaminate the sample.  ZDT is a measure of the internal bond strength of paper or paperboard. It is particularly useful for measuring the internal bond strength of single-ply sheets.
