1. Function

Tape initial adhesion ball testing machine
is used to test the initial adhesion of pressure sensitive tape and the like. It’ s easy to operate with high practicability.

2. Theory

Let the steel ball roll over the tape placed on the leaning surface, valuate its initial adhesion according to the size of the maximum ball that the given tape length can stick.
