Processing Characteristics
Cutting & Fabrication:
Precision Die Cutting: Tolerance ±0.1mm, minimum corner radius R0.5mm.
Laser Cutting: CO₂ laser, power 30-50W, speed 8-12 mm/s.
CNC Cutting: Sharp blade, feed rate 15-20 m/min.
Surface Treatment:
1. Glossy side can undergo:
Screen printing (150-200 mesh screen).
UV inkjet printing (resolution ≥720 dpi).
Hot stamping (temperature 110-130°C).
Hard coating (hardness up to 3H).
2. Frosted side treatment limitations:
Not recommended for direct printing (requires special treatment).
Can be laminated with protective film (low-tack PE film).
Can undergo secondary embossing (requires special molds).
Lamination Processing:
With transparent sheets: Increases thickness while maintaining transparency.
With colored sheets: Creates gradient/dual-color effects.
With functional films: Lamination for anti-shatter, UV-blocking, anti-fog properties.
