High Light 50μm CPE Base Film ，High Tensile Strength Cast Polyethylene Film ，Good Tear Resistance LDPE Film
50μm Black CPE Base Film
High tensile strength, excellent tear resistance, smooth surface finish, lamination-compatible, optional anti-static treatment. Ideal for industrial packaging and surface protection applications.
Production Process
Manufactured through high-precision cast extrusion technology using high-purity LDPE resin uniformly mixed with light-fast black masterbatch. The material undergoes temperature-controlled extrusion (165-185℃), precision flat die casting onto mirror-polished cooling rollers, followed by edge trimming, tension control, and static neutralization to produce defect-free rolls with stable 50μm thickness.
Key Features
  • Strict thickness tolerance of ±4% for uniform density and performance
  • Opaque black appearance with excellent light-blocking and UV-shielding
  • Outstanding color fastness resistant to fading during processing and storage
  • Balanced mechanical properties with good tensile strength and tear resistance
  • Reliable low-temperature toughness (-10℃ to 60℃)
  • Ultra-smooth surface compatible with lamination and coating processes
  • Optional anti-static treatment available
Product Advantages
Achieves perfect balance between thickness and performance—lightweight yet durable, easy to process while providing effective light shielding. Uniform opaque black color facilitates quick visual identification in production lines, improving sorting efficiency. Excellent batch-to-batch consistency minimizes conversion waste. Non-toxic, odorless, and compliant with industrial standards.

Application Environment
Widely used in industrial scenarios requiring light shielding and privacy protection, including electronic component packaging, mechanical part wrapping, light-blocking industrial packaging, and privacy film base material. Performs stably in dry, normal-temperature environments and moderate low-temperature storage (≥-10℃), maintaining excellent performance during high-speed slitting, lamination, and coating processes.
