Product Description
80μm Black CPE Base Film
This heavy-duty 80μm black cast polyethylene base film offers exceptional light-blocking capabilities, high tensile strength, tear resistance, and a smooth surface ideal for industrial applications. Designed for lamination compatibility with optional anti-static properties.
Production Process
Manufactured using advanced precision cast extrusion technology, this film begins with high-purity LDPE resin uniformly blended with light-fast black masterbatch. The compound undergoes temperature-calibrated extrusion (170-190℃) through precision flat dies, followed by rapid solidification on mirror-polished cooling rollers. Final processing includes edge trimming, tension control, and static neutralization to produce defect-free rolls with consistent 80μm gauge and smooth surface finish.
Key Features
- Strict thickness tolerance of ±4% for uniform density and performance
- Opaque black appearance with excellent light-blocking and UV-shielding
- Superior color fastness resistant to fading during high-temperature processing
- Exceptional tensile strength and high tear resistance
- Reliable low-temperature toughness (-10℃ to 65℃)
- Ultra-smooth surface for seamless lamination and coating compatibility
- Optional anti-static treatment available for specialized applications
Product Advantages
The 80μm heavy-gauge structure provides optimal balance between durability and processability. Uniform opaque black coloring enables quick visual identification in production lines, improving sorting efficiency. Batch-to-batch consistency in color and thickness minimizes conversion errors. Non-toxic, odorless, and compliant with global industrial standards, this film offers cost-effective performance with reliable bulk supply.
Application Environment
Ideal for heavy-duty industrial applications including light-blocking packaging, mechanical part wrapping, automotive component shielding, and privacy protection films. Performs reliably in dry, normal-temperature environments and moderate low-temperature storage (≥-10℃). Maintains stability during high-speed slitting, lamination, and coating processes.
