Optimizing Creasing Tool Geometry for Barrier Coated Boxboard Converting
Optimizing creasing geometry for barrier board requires expanding female channel width and applying polished male rule radii to prevent barrier film splitting.
Pressboard Channel Tape
Setup Material
Preparation of the die-cutting station for short or medium production runs involves the use of adaptable creasing guides. Pressboard channel tape is a self-adhesive matrix made from high density paperboard that is used to form creases in the carton. It provides a cost effective solution for converters who need to set up a job quickly.
Adhesive Bond
The tape is applied to the counter plate and the carrier is removed to reveal the pre-formed channel. Each strip is aligned with the creasing rule to ensure the board is pushed into the center of the groove. The material is flexible enough to follow the curves and angles of a complex die layout.
As the press runs the pressboard fibers eventually begin to compress and wear down. This type of matrix is best suited for jobs where the total number of impressions is relatively low. Accurate selection of the channel width prevents the board from cracking or being under-creased.
Durability Profile
The performance of the tape depends on the quality of the adhesive and the density of the pressboard. Humidity changes in the pressroom can affect the stability of the paper based material. This product defines the entry level for professional creasing in the packaging industry.
It provides a reliable way to produce high quality folds on standard die-cutting equipment.
