60μm Red CPE Base Film
This premium red cast polyethylene base film features a smooth surface, excellent processability, and consistent batch-to-batch performance. Ideal for lamination, coating, and industrial converting applications. Anti-static functionality available upon request.
Production Process
Manufactured using state-of-the-art precision cast extrusion technology, this film begins with high-grade LDPE resin blended with fade-resistant red masterbatch for uniform color dispersion. The compound undergoes controlled melting (165-185℃), precision extrusion through a flat die, and rapid solidification on mirror-polished cooling rollers. Final processing includes precision edge trimming, tension calibration, and static neutralization to ensure defect-free rolls with consistent gauge and surface quality.
Key Features
- Strict thickness tolerance of ±4% for uniform performance
- Vibrant, fade-resistant red color with exceptional color fastness
- Balanced tensile strength and tear resistance
- Excellent flexibility and low-temperature toughness (-10℃ to 60℃)
- Ultra-smooth surface for superior lamination and coating compatibility
- Customizable anti-static or anti-slip modifications available
Product Advantages
- Vivid, consistent red color for quick product sorting and visual identification
- Exceptional batch-to-batch consistency minimizes conversion waste
- Cost-effective formulation with premium mechanical properties
- Versatile processability for seamless industrial integration
- Non-toxic, odorless, and compliant with global industrial standards
- Scalable production capacity for reliable bulk supply
Application Environment
Optimized for industrial packaging, surface protection, and composite manufacturing applications. Excellent performance in automotive component wrapping, electronic part shielding, and colored protective packaging for mechanical parts. Maintains stability in dry, normal-temperature environments and moderate low-temperature storage (≥-10℃), supporting high-speed slitting, lamination, and coating processes.
