80μm Base Film 25μm Emboss Depth Green-Black Dual-Color Cast Polypropylene Film for Industrial Marking
80μm Base Film with 25μm Emboss Depth for High-End Stationery & Industrial Marking
Crafted via precision cast co-extrusion and in-line micro-embossing, this 80μm cast polypropylene (CPP) base film features a defined 25μm green-black dual-tone textured surface, engineered for industrial protection, premium packaging, and structural masking applications.
Built on a high-speed cast PP line with multi-layer co-extrusion, uniform melt distribution through a T-type die, and rapid chill-roll setting to lock dimensional stability. In-line micro-embossing with precision engraving rollers transfers a consistent 25μm texture depth, while dual-color masterbatch dispersion ensures crisp green-black contrast without streaking.
- Stable 80μm base thickness with sharp 25μm embossed pattern depth
- High rigidity, good flexibility, and outstanding anti-puncture & tear resistance
- Non-slip textured surface with low glare and excellent concealment
- Uniform green-black dual coloring, no fading or color migration
- Excellent flatness, low shrinkage, and stable converting performance
- Good chemical resistance, moisture barrier, and dust-repellent properties
- Balanced thickness and texture deliver superior cushioning and scratch protection
- Dual-tone embossed surface enhances grip, reduces reflection, and improves product aesthetics
- Strong structural stability prevents wrinkling during die-cutting, lamination, and wrapping
- Outstanding machinability for high-speed automated processing
- Recyclable PP composition supports eco-friendly manufacturing
- Ideal balance of concealment and partial light transmission for visual inspection
Suited for industrial surface protection, automotive component masking, electronic product packaging, hardware anti-scratch wrapping, and premium consumer goods packaging. Performs reliably in normal temperature assembly, logistics transport, storage, and automated converting environments, providing durable protection with professional visual presentation.
