Suitable for different needs
There is no single standardized system for the classification of paper and paperboard grades. The different systems developed for different purposes differ considerably from each other, as do systems created in geographically different locations – American, Japanese, etc. They may even use local standards that are not recognized anywhere else. The attached pdf presents the most common classification system, based on the end use of the different paper and board grades.
Classification of typical paper and board grades
Paper Lab systems have been installed in several board mills around the world. While the testing methods are largely the same as those used in the testing of paper, a range of typical measurements specific to board have been taken into use in daily quality control.
