Creasing Matrix

A creasing matrix is a precision consumable used in the die-cutting and packaging industry to create clean, accurate folds (creases) in paperboard, cardstock, or corrugated board. It acts as the "female" part of the creasing pair. While a metal creasing rule (the "male" part) pushes the board from above, the creasing matrix provides a precisely sized channel underneath to receive the board, ensuring it bends without cracking or tearing.
