Product Description
80μm CPP Red-Black Dual-Color Embossed Film
80μm base film with 25μm uniform emboss depth, featuring red-black dual-color construction, color stability, high stiffness, high tensile strength, tear resistance, printability, and heat-sealability.
Production Process
Crafted with advanced co-extrusion casting and high-precision embossing technology. High-purity CPP resin is molten in a temperature-calibrated extruder (160-180℃), then co-extruded with red & black masterbatches to form a rigid 80μm dual-color base film (red top/black bottom). After precision cooling, it undergoes embossing under 100-110℃ & 0.2-0.3MPa for a uniform 25μm fine cloth grain finish, followed by corona treatment, trimming and winding into consistent, defect-free rolls—ensuring industrial-grade production stability.
Core Features
- 80μm ultra-stiff base film with 25μm evenly formed emboss depth
- Vivid red-black dual-color with permanent color fastness (UV-resistant, no fading/bleeding)
- Superior mechanical performance: high tensile strength and exceptional tear resistance
- Rigid Shore D hardness and strong emboss adhesion (3M tape peel-tested, no shedding/color loss)
- Corona-treated surface (≥40mN/m) for high printability
- High heat seal strength, oil/moisture barrier, and food-contact grade compliance (GB 4806.7-2016)
Product Advantages
80μm heavy-gauge base film delivers unmatched stiffness + durable toughness—no deformation for long-term use, ideal for structural applications. 25μm delicate emboss elevates tactile grip and visual layering, adding premium value to end products. Red-black co-extrusion ensures color uniformity across batches; high print/heat-seal compatibility enables seamless post-processing. Food-grade eco-safe, oil/moisture resistant, and mass production stable—blending performance and practicality for mid-high end scenarios. Custom emboss patterns available for personalized needs.
Application Environment
A premium choice for mid-high end stationery (hardcover notebook covers, luxury album shells, rigid file folders) leveraging its ultra-stiffness and exquisite emboss texture. Perfect base material for heavy-duty industrial identification tapes (anti-tear, anti-slip) and mid-high end small food packaging (food-safe, moisture/oil barrier). Also applicable to precision industrial protective packaging; performs stably in 0℃-60℃ normal temperature environments, adapting to high-speed slitting, printing and heat-sealing industrial processes.
