90μm Base Film 25μm Emboss Depth Green-Black Dual-Color CPP Film for High-End Stationery and Packaging
A high-performance cast polypropylene (CPP) film engineered with 90μm stable base thickness and precise 25μm embossed pattern depth, integrated with green-black dual-color technology. Designed to balance structural robustness, visual concealment, and processing adaptability for diverse industrial and packaging applications.
Manufactured through advanced multi-layer cast co-extrusion technology using high-purity PP resin melted and uniformly extruded through precision T-die systems. Rapid chill-roll cooling locks in the 90μm base thickness with ±2μm tolerance, while in-line precision embossing using engraved rollers transfers clear 25μm patterns without structural damage. Green and black masterbatches ensure uniform color dispersion with no streaking or migration. Real-time monitoring systems maintain consistent product quality throughout production.
- Structurally stable 90μm base thickness with sharp, consistent 25μm embossed pattern
- Green-black dual-color design with excellent color saturation and fade resistance
- Superior mechanical properties: high tensile strength, flexibility, and puncture resistance
- Non-slip embossed surface reduces glare and enhances grip performance
- Low thermal shrinkage and excellent flatness for stable converting performance
- Good chemical resistance, moisture barrier, and dust-repellent properties
- Enhanced structural rigidity and load-bearing capacity for superior product protection
- Precise embossing improves grip and prevents slipping during processing
- Excellent dimensional stability reduces production waste and improves efficiency
- Integrated dual-color and embossing process lowers production costs
- Food-grade compatible PP material, non-toxic, odorless, and recyclable
- Superior concealment with moderate light transmittance for visual inspection
Widely applicable in industrial and commercial fields including automotive component masking, industrial surface protection, electronic product packaging, hardware and tool wrapping, and premium consumer goods packaging. Performs reliably in normal temperature (0-40℃) assembly lines, logistics, warehousing, and high-speed automated converting environments. Suitable for both indoor and outdoor short-term storage with excellent resistance to moisture, dust, and minor impacts.
