80μm Green CPE Base Film
Engineered for heavy-gauge reliability, this 80μm green cast polyethylene base film is manufactured through advanced precision cast extrusion. High-purity LDPE resin is homogenously blended with high-concentration, light-fast green masterbatch, ensuring deep, consistent color that resists fading throughout processing and storage.
Production Excellence
The compound undergoes precise melting in temperature-calibrated extruders (170-190℃) for complete fusion, then extrudes through high-precision flat dies onto mirror-polished cooling rollers for rapid, uniform solidification. Post-extrusion processes include strict thickness calibration, constant tension control, static neutralization, and precision edge trimming, resulting in defect-free rolls with smooth surfaces, consistent 80μm gauge, and vivid, long-lasting green coloration.
Key Performance Features
- Strict ±4% thickness tolerance for uniform density and performance
- Exceptional heat and light fastness with vibrant green color retention
- Superior tensile strength and high tear resistance
- Reliable flexibility with excellent low-temperature toughness (-10℃ to 65℃)
- Ultra-smooth surface for seamless lamination and coating compatibility
- Optional anti-static treatment for specialized industrial requirements
Product Advantages
Distinguished by its 80μm heavy-gauge structure and vivid green coloration, this film enables quick visual identification in high-volume production lines, streamlining sorting processes and boosting operational efficiency. The enhanced durability and puncture resistance minimize damage during handling and converting operations. Exceptional batch-to-batch consistency in color and thickness reduces conversion waste, while the cost-effective formulation combines premium mechanical properties with affordability. The film is non-toxic, odorless, and compliant with industry standards, supporting versatile processing and steady bulk supply for long-term industrial applications.
Application Environment
Optimized for heavy-duty industrial scenarios, this 80μm green CPE base film excels in industrial packaging, heavy-duty surface protection, automotive component wrapping, and mechanical part shielding. It performs reliably in dry, normal-temperature environments and moderate low-temperature storage (≥-10℃), maintaining stability during high-speed slitting, lamination, and coating processes. Ideal for manufacturers seeking visually distinct, high-performance base films requiring enhanced durability, color stability, and seamless compatibility with industrial converting operations.
