Product > Rotary Creasing Rules > Rotary Creasing Rules
The Snadvik/National partnership is further enhanced with a range of creasing rules.
The important of a creasing rule should never be underestimated – it is a critical factor in controlling the sheet as it passes through the diecutter.
Using a crease that is too high may result in cracked scores while a crease that is too low may create dimensional problems.

National Standard
A complete range of standard creasing rules from 3 point through to 8 point. Creasing rules are available with either a radius profile or a flat top.
A large level of stocks are held in all standard heights, curved to fit all major rotary diecutters.
| Thickness | Height |
| 3pt (1.07mm) | 10mm (0.394") - 101.6mm (4.00") |
| 4pt (1.42mm) | 12mm (0.472") - 101.6mm (4.00") |
| 6pt (2.14mm) | 76.2mm (3.00") max. |
| 8pt (2.84mm) | 50.8mm (2.00") max. |

National Laser Crease
It is designed to save time by eliminations the need to cut 6 and 8 point lines and its 4 point body makes it much easier to notch.
Laser crease is made from a solid piece of tempered steel which means the head will not separate from the base during discutting.
| Thickness | Height |
| 6pt (2.14mm) on 4pt (1.42mm) | 19.05mm (0.75") - 23.62mm (.93"). |
| 8pt (2.84mm) on 4pt (1.42mm) | 19.05mm (0.75") - 23.62mm (.93"). |
| Available Size: | |||
| 3 on 2 | 4 on 2 | 4 on 3 | 6 on 3 |
| 8 on 3 | 6 on 4 | 8 on 4 | |
National TruFold Laser
The bead on the head provides an accurate location for the creasing rule. This ensures accurate creasing and eliminates the problem of ‘roll’ frequently faced while creasing corrugated board along the direction of the corrugations.
