Corrugated Paper Smoothness Detector

The corrugated paper smoothness tester evaluates surface flatness by measuring the air leakage rate between the paper surface and a standard pressure head. Under constant pressure, the instrument records the airflow rate, with the values directly reflecting the microscopic roughness of the paper surface. It is primarily used for inspecting the surface quality of packaging materials such as corrugated cardboard liner and boxboard, providing data support for printability and packaging strength.
Selection
When selecting, pay attention to the measurement range to ensure it covers the paper types to be tested, and the accuracy should meet industry standards. The instrument's indenter size and test pressure should comply with specifications such as GB/T 456. The operation interface should be user-friendly, with data storage and output functions. Consider the stability and maintenance costs of the equipment, ensuring the measurement head is wear-resistant and easy to calibrate. Prioritize equipment that complies with standards such as ASTM D1894 or ISO 8791-2.
