100μm Green CPE Base Film
High tensile strength, tear-resistant, puncture-resistant cast polyethylene film with smooth surface, excellent lamination compatibility, and optional anti-static properties for industrial packaging and surface protection applications.
Production Process
Precision cast extrusion process using high-grade LDPE resin homogeneously blended with light-fast green masterbatch. Melted at 170-190°C, extruded through high-precision flat die, and cast onto mirror-polished cooling rollers for controlled solidification. Strict thickness calibration, tension control, static neutralization, and precision edge trimming ensure consistent 100μm gauge with fade-resistant green color and blemish-free surface.
Key Features
- ±4% thickness tolerance for uniform density and stable performance
- Vibrant green color with exceptional heat and light fastness
- Superior tensile strength, tear resistance, and puncture resistance
- Excellent flexibility and low-temperature toughness (-10°C to 65°C)
- Ultra-smooth surface for seamless lamination and coating compatibility
- Optional anti-static treatment available
Product Advantages
Quick visual identification streamlines sorting processes in high-volume production lines. Perfect balance between thickness and flexibility outperforms thinner films in durability while remaining easy to process. Exceptional batch-to-batch consistency minimizes conversion waste. Cost-effective formulation delivers premium mechanical properties. Non-toxic, odorless, and compliant with global industrial standards.
Application Environment
Optimized for medium-heavy industrial scenarios including industrial packaging, heavy-duty surface protection, automotive component wrapping, mechanical part shielding, and colored composite lamination. Performs reliably in dry, normal-temperature environments and moderate low-temperature storage (≥-10°C). Maintains stability during high-speed slitting, lamination, and coating processes.
