90μm Base Film 25μm Emboss Depth Purple-Black Dual-Color CPP Film for High-End Packaging
A high-strength cast polypropylene (CPP) film engineered with a 90μm robust base thickness and precisely crafted 25μm embossed texture, enhanced by an elegant purple-black dual-color finish. This film integrates superior structural sturdiness, refined visual sophistication, and exceptional processing versatility for premium aesthetic presentation and reliable heavy-duty protection.
Manufactured using advanced multi-layer cast co-extrusion technology with high-purity PP resin. The process ensures uniform melt distribution and consistent 90μm base thickness control (±2μm tolerance). In-line precision embossing creates a sharp, uniform 25μm pattern depth while purple and black masterbatches provide rich, streak-free dual-color contrast with excellent color fastness.
- Sturdy 90μm base thickness with precise 25μm embossed pattern for optimal structural rigidity and flexibility
- Elegant purple-black dual-color design with rich color saturation and superior color fastness
- Outstanding mechanical properties: high tensile strength, flexibility, and anti-puncture/tear/scratch resistance
- Non-slip embossed surface minimizes glare and enhances grip for easier handling
- Low thermal shrinkage, excellent flatness, and stable converting adaptability
- Strong chemical resistance, reliable moisture barrier, and effective dust-repellent properties
- Enhanced structural sturdiness and load-bearing capacity for heavy-duty protection
- Precise embossed pattern combines functional practicality and aesthetic appeal
- Superior dimensional stability eliminates wrinkling and warping during processing
- Integrated dual-color and embossing process reduces production costs
- Food-grade compatible PP material - non-toxic, odorless, and recyclable
- Optimal balance of concealment and moderate light transmittance
Widely applicable in premium consumer goods packaging (cosmetics, skincare, electronics, luxury accessories), electronic component packaging, heavy-duty industrial surface protection, large-scale gift wrapping, and high-end retail display packaging. Performs reliably in normal temperature environments (0-45℃) including retail stores, warehouses, logistics transportation, and automated converting lines.
