Perforation is the process of creating defined hole or slit patterns in materials to increase breathability and support fluid management. The result is perforated rollstock manufactured to a specified open area percentage, using controlled hole geometries such as 1.6 mm, 3 mm, or 4 mm.
In medical constructions, perforation is applied where moisture vapor transmission and flow through performance must be engineered without compromising material integrity.
Perforation introduces a controlled open area into films or adhesive constructions. By defining hole size, spacing, and pattern, it enables targeted performance adjustments in otherwise non breathable materials.
The output is perforated rollstock produced to define open area specifications and repeatable pattern tolerances.
Ultrasonic perforation is a process used to generate precise and consistent hole patterns. It supports controlled open area targets and repeatable geometries such as 1.6 mm. This approach enables stable processing of perforated rollstock for applications where breathability and fluid transfer must be managed within defined design parameters.
Perforation is used when MVTR needs to be increased in films that are otherwise non breathable. By introducing a defined open area, it:
This allows design teams to adjust transmission properties without fully changing base material selection.
Perforation is commonly applied in:
These applications require controlled moisture handling and consistent structural performance.
Perforation supports defined open area percentages while maintaining structural integrity of the base material. This enables optimized flow through performance while preserving mechanical stability in finished medical constructions.
Perforation is performed in controlled environments to support clean processing and reduce contamination risk. This protects material quality during manufacturing, particularly for skin contact applications.
Perforation can be applied to thin films and heavy coat adhesive builds. This supports flexibility in construction design and allows breathability and flow through performance to be integrated without altering the overall material platform.
