Product Description
120μm Black CPE Base Film
Premium fade-resistant masterbatch, uniform gauge, light-blocking properties, high tensile strength, tear-resistant, puncture-proof, smooth surface, lamination-compatible, with optional anti-static treatment.
Production Process
Manufactured through advanced high-precision cast extrusion technology using high-purity LDPE resin uniformly blended with high-concentration, light-fast black masterbatch. The process ensures deep, consistent color penetration and excellent opacity through temperature-regulated extrusion (175-195℃), precision flat die casting, and rapid solidification on mirror-polished cooling rollers.
Key Features
- Strict thickness tolerance of ±4% for uniform density and stable mechanical performance
- Superior light-blocking and UV-shielding capabilities with excellent color fastness
- High tensile strength, tear resistance, and robust puncture-proof performance
- Reliable flexibility and low-temperature toughness (-10℃ to 65℃)
- Ultra-smooth surface for seamless lamination and coating compatibility
- Optional anti-static treatment available for specialized requirements
Product Advantages
Heavy-gauge 120μm structure provides superior durability and load-bearing capacity, preventing damage during handling and transportation. Uniform opaque black color enables quick visual identification in production lines, while exceptional batch-to-batch consistency minimizes conversion waste. Non-toxic, odorless, and compliant with global industrial standards.
Application Environment
Optimized for heavy-duty industrial applications including light-blocking packaging, surface protection, automotive component wrapping, mechanical part shielding, and privacy protection films. Maintains structural stability in dry, normal-temperature environments and moderate low-temperature storage (≥-10℃) during high-speed processing operations.
