Appita 1301.426

Introducing Appita 1301.426 - Industrial Physics

Appita 1301.426 is an Appita testing method to measure the thickness, density and specific volume of paper and paperboard.  

Appita is the leading not-for-profit industry association that supports the advancement of the pulp, paper packaging and bioproducts industries. 

The thickness, density and volume of the paper, paperboard and corrugated used in your packaging is vitally important. The thickness of paper and paperboard not only affects its strength and durability, its appearance and tactile feedback also gives the customer a direct impression of quality. 

Armed with a digital micrometer from Industrial Physics and the method described through Appita 1301.426 you will command confidence over your thickness testing, density testing and specific volume paper testing.
