Specialty Grades of Paper

Understanding Specialty Paper Grades Classifications

Primary Classification Systems


Specialty Paper Grades are typically classified using multiple criteria including basis weight, end-use applications, manufacturing processes, raw material composition, and surface treatments. The European EN643 standard provides comprehensive guidelines for categorizing paper materials into ordinary, medium, high, kraft, and special grades based on contamination levels and processing requirements.

Industrial classification systems distinguish between functional categories such as packaging grades (containerboard, boxboard, kraft paper), graphic grades (newsprint, wood-containing, woodfree), and specialty applications including security papers, technical grades, and decorative materials. Each category demands specific manufacturing processes and quality control parameters.

The most comprehensive classification approach considers both physical properties and intended applications. Specialized Paper Products within each category require unique manufacturing expertise, often necessitating consultation from experienced Paper Manufacturing Consultant professionals to optimize production parameters and quality specifications.


Basis Weight and Thickness Standards

Paper classification fundamentally relies on grammage (grams per square meter), with tissue papers typically ranging from 15-60 g/m², standard papers from 30-170 g/m², and paperboard exceeding 134 g/m². These weight classifications directly influence manufacturing processes and end-use applications.

Specialty Paper Grades often exceed conventional weight ranges, particularly for technical applications requiring enhanced mechanical properties. Electrical insulation papers, for example, are classified by thickness with tissue grades under 1.5 mils (0.0381 mm) and board grades exceeding 20 mils (0.508 mm).
