Print-grade PC sheet

Print-grade PC sheet Print-grade PC sheet
Printing Grade transparent PC film and sheet are produced via precision extrusion and calendering using high-quality polycarbonate (PC) resin. They are specially engineered for various printing and graphic patterning processes with the following core merits:
  • Excellent printability: Precisely controlled surface energy and flatness compatible with screen printing. The substrate delivers strong ink adhesion, crisp graphic edges, and crack-resistant printed layers after bending.
  • Superior dimensional stability: Low internal stress and molecular orientation minimize deformation under heat or moisture, ensuring accurate registration during printing and consistent precision in subsequent die-cutting and stamping.
  • Retained inherent advantages of PC material: Lightweight, transparent, high impact resistance, wide temperature tolerance, electrical insulation and intrinsic flame retardancy. Compatible with secondary processing including hard coating, vacuum metallization (mirror finish) and thermoforming.

Difference from Optical Grade PC (Brief Summary)

Optical Grade PC prioritizes ultra-high light purity with strict limits on fish eyes and iridescence, designed for display windows and instrument protective lenses. Printing Grade PC focuses on reliable ink adhesion and broad processing windows, serving as printing carriers and graphic decorative panels.

Standard Specifications (Official Factory Data)

  • Base Material: Polycarbonate (PC)
  • Thickness: 0.05–4.0 mm, covering ultra-thin films to thick solid sheets in one product line
  • Maximum Width: 1400 mm; common shipping widths include 915 mm, 1000 mm and 1220 mm
  • Color: Natural transparent as standard; opaque and tinted variants fall under colored PC and opaque colored PC product lines
  • Surface Finish: Double-sided polished (Polished/Polished) as standard. Single-sided polished/matte (Polished/Matte) texture is available upon request for light masking, tactile texture and anti-glare control.
  • Delivery Form: Custom-length rolls or cut-to-size sheets, packed on plastic pallets; minimum order quantity: 1 ton

Typical Applications

Overlay layers for membrane switches, base films for nameplates and decorative labels, graphic substrates for home appliance and industrial control panels, decorative overlays for instrument panels, decorative bezels for display peripherals, carrier films for anti-counterfeit markings and barcodes, and all industrial decorative components requiring durable transparent substrates paired with high-precision printed graphics.
