APPLICATION GUIDE · BFS PACKAGING
UV Picosecond Laser Marking for BFS Single-Dose Eye Drop Packaging
Transparent single-dose eye drop packs provide very little marking area but may need several lines of product, batch and date information. This application combines a real marking sample with a dual-laser engineering concept for a 25-up BFS panel.
Why this BFS marking task is demanding
The process must control small text, low natural contrast, thin packaging walls, variable data, panel positioning and repeatability. Appearance alone cannot confirm container integrity, line speed or regulatory suitability.
Why evaluate UV picosecond marking
Short UV picosecond pulses can support fine feature definition and a controlled material response when the process is correctly tuned. The technology is non-contact and forms the mark without ink or ribbon, but representative production samples remain essential.
VORANIX
Choose the required solution level
A. Standalone marking
Laser source, controller, fixture or handling, laser-safe enclosure, interlocks and suitable extraction.
B. Mark and verify
Add controlled product handling, trigger or encoder, lighting, camera, inspection logic and alarm or reject.
C. Traceability-ready line
Add batch and message management, permissions, records and scoped PLC, MES, ERP or WMS interfaces.
What must be validated before production
Confirm the real packaging material, required code, available mark area, cycle rate, inspection criteria, handling and storage conditions, container-integrity requirements, laser safety, extraction and data ownership.
Engineering data required for selection
- Exact resin, colour, additives and wall thickness
- Required text, code size and marking position
- Cycle rate, panel pitch and product stability
- Readability, OCR/OCV or code-verification criteria
- Container integrity, guarding and extraction requirements
FAQ
UV picosecond laser marking FAQ
Can every transparent eye drop package be marked?
No universal result can be promised. Material formulation and wall thickness affect the response, so representative samples must be tested.
Can the system mark variable batch and expiry data?
Yes, when an approved controller and data source are included. Templates, permissions and change control must be defined for the project.
Can vision inspect the small white characters?
Potentially. The camera, lens, lighting and inspection task must be selected for the real character size, contrast, position and cycle rate.
