90μm Base Film 25μm Emboss Depth Yellow-Black Dual-Color CPP Film
Premium cast polypropylene film engineered for high-end stationery and industrial packaging applications, featuring exceptional stiffness, vivid dual-color appearance, and superior mechanical properties.
Production Process
Manufactured using precision co-extrusion casting and high-torque embossing technology. High-purity CPP resin is processed at 160-180°C, co-extruded with high-opacity yellow and black masterbatches to form a 90μm dual-color base film (22μm yellow top layer/68μm black bottom layer). After precision cooling and shaping, the film undergoes embossing at 100-110°C under 0.2-0.3MPa pressure for uniform 25μm fine cloth grain finish, followed by corona treatment, micro-trimming, and tight winding to produce defect-free rolls with ultra-low batch deviation (≤3%).
Core Features
- 90μm ultra-stiff heavy-gauge base film with 25μm uniform emboss depth
- High-visibility vivid yellow-black dual-color with industrial-grade color fastness
- Superior mechanical performance: tensile strength ≥24/22MPa (MD/TD)
- Excellent tear resistance ≥17/14N (MD/TD) and Shore D hardness 57±3HD
- Corona-treated surface (≥40mN/m) for high-definition printing compatibility
- Robust heat seal strength (≥13N/15mm) with upgraded oil/moisture barrier
- Food-contact grade compliant (GB 4806.7-2016), odor-free and safe
Product Advantages
The 90μm ultra-stiff base film provides unmatched structural rigidity and robust toughness, resisting deformation for long-term heavy-duty use. The 25μm delicate emboss enhances anti-slip tactile grip and visual layering, while the high-visibility yellow-black color scheme offers exceptional safety warning and identification performance. Co-extrusion process ensures permanent color fastness without fading or bleeding, with excellent print and heat-seal compatibility for seamless post-processing.
Application Environment
Ideal for luxury stationery including high-end hardcover folder covers, premium thick notebook shells, and luxury album binders. Perfect for heavy-duty industrial safety warning and marking tapes due to excellent tear resistance and anti-slip performance. Also suitable for premium medium food packaging and heavy industrial protective packaging. Performs stably in 0°C-65°C environments and adapts perfectly to high-speed slitting, high-definition digital printing, and automated heat-sealing industrial processes.
