Corte Longitudinal de Filme de Transferência Holográfico
Holographic transfer film carries micro-embossed optical structures and may include release, metallized and protective coatings on a PET carrier. Slitting defects can be visually amplified by diffraction. Review should identify which layer transfers, the optical repeat direction and whether edge debris could contaminate stamping or transfer equipment.
Onde esta aplicação de corte é utilizada
Hot-stamping foil reels
Prepare narrow transfer rolls for decorative or security stamping applications.
Registered holographic transfer webs
Convert reels while preserving optical-repeat orientation and edge registration.
Decorative laminate transfer film
Supply clean, stable rolls for downstream heat and pressure transfer.

Problemas a diagnosticar antes de trocar a lâmina
Metallic or optical coating flakes at the edge
- Identify coating and release-layer order.
- Inspect flake origin under magnification.
- Compare support, tension and winding direction.
Holographic pattern appears damaged near the slit
- Use controlled directional lighting.
- Map contact and compression zones.
- Check debris trapped in the roll edge.
Narrow reel telescopes
- Review winding tension and core alignment.
- Check carrier thickness and roll hardness.
- Separate edge quality from rewind control.
Transfer process shows edge contamination
- Collect edge particles after slitting.
- Inspect coating adhesion and roll packing.
- Compare contamination location downstream.
Tipos de lâmina que podem ser considerados
| Possível tipo de lâmina | Quando pode ser considerado | O que deve ser confirmado |
|---|---|---|
| Circular shear slitting arrangement | For supported conversion of coated PET transfer webs into narrow reels. | Confirm coating side, overlap, side load, holder, rotation, core and approved edge sample. |
| Razor slitting arrangement | For compatible thin carrier constructions on clean, purpose-designed razor stations. | Confirm coating sensitivity, support mode, holder, exposure, extraction and speed. |

Perguntas sobre esta aplicação de corte
Why are small edge defects highly visible on holographic film?
Diffractive structures redirect light, so scratches, compression and coating loss can create strong contrast.
Does optical repeat affect slitting?
It can affect inspection, reel orientation and registered downstream use, so repeat and web direction should be documented.
Can coating flakes contaminate transfer?
Yes. Loose edge particles may enter the stamping or transfer interface and create recurring defects.
Which side should face outward on the slit reel?
Follow the downstream transfer and handling specification rather than assuming one winding orientation.
What sample lighting is useful?
Inspect under repeatable diffuse and directional light because some damage is visible only at certain angles.
