80μm Brown CPE Base Film
Vivid color, high tensile strength, tear-resistant, smooth surface, lamination-compatible, optional anti-static treatment. Ideal for industrial packaging, surface protection, and demanding applications requiring durability and cost-effectiveness.
Production Process
Manufactured via advanced precision cast extrusion technology using high-purity LDPE resin homogenously blended with high-concentration, light-fast brown masterbatch. The process ensures uniform color dispersion and long-lasting vividness through temperature-calibrated extrusion (170-190℃), precision flat die casting onto mirror-polished cooling rollers, and strict quality control including edge trimming, tension control, and static neutralization.
Key Features
- Strict thickness tolerance of ±4% for uniform density and stable performance
- Vivid, consistent brown color with excellent light fastness
- Superior tensile strength and high tear resistance
- Good flexibility with reliable low-temperature toughness (-10℃ to 65℃)
- Ultra-smooth surface for seamless lamination and coating compatibility
- Optional anti-static treatment available for specialized industrial needs
Product Advantages
This 80μm heavy-gauge brown CPE film balances durability and processability, offering more robustness than thinner alternatives while remaining easy to convert. The uniform brown hue enables quick visual identification in production lines, boosting sorting efficiency and reducing waste. Excellent batch-to-batch consistency in color and thickness minimizes conversion errors. Non-toxic, odorless, and compliant with global industrial standards, it combines heavy-duty performance with cost-effectiveness.
Application Environment
Optimized for heavy-duty industrial scenarios including industrial packaging, mechanical part wrapping, automotive component shielding, and colored composite lamination. Performs reliably in dry, normal-temperature environments and moderate low-temperature storage (≥-10℃), maintaining stability during high-speed slitting, lamination, and coating processes.
