- Quality and Quantity of paper
- Quality and Quantity of adhesive
- Manufacturing process
- Moisture content in the carrier
- Physical size and dimensions
It is very difficult for a user to know all the above factors and their influence on the strength of the carrier. It is equally difficult for a manufacturer to know the effect of each variable quantitatively.
But it is very easy for both the user and manufacturer to differentiate between good and bad and adopt a suitable standard of monitoring the quality of the carrier.
Collapsing strength tester is designed in such a manner that gradually increasing force is generated & applied on the surface of the paper cone. The sharp collapsing point can be easily detected on a dial-type pressure gauge and a suitable reading can be taken.
