80μm Red CPE Base Film
Premium fade-resistant masterbatch, uniform gauge, vivid red coloration, excellent tensile strength, high tear resistance, smooth surface, reliable processability, and lamination-compatible performance.
Production Process
Crafted with high-precision cast extrusion technology tailored for thick-gauge films, this 80μm red CPE base film begins with high-quality LDPE resin, homogenously blended with high-concentration, light-fast red masterbatch to ensure consistent color penetration. The compound is melted in a temperature-controlled extruder (170-190℃) for full fusion, then extruded through a precision flat die and cast onto a mirror-polished cooling roller for rapid, uniform solidification. Post-extrusion, it undergoes precise edge trimming, constant tension control, and static neutralization before being wound into tight, defect-free rolls—delivering consistent 80μm gauge, vivid red hue, and a smooth, blemish-free surface ideal for industrial processing.
Key Features
- Strict thickness tolerance of ±4% ensures uniform density and performance
- Vibrant, fade-resistant red color with exceptional heat and light fastness
- Superior tensile strength and high tear resistance for enhanced durability
- Excellent flexibility with reliable low-temperature toughness (-10℃ to 65℃)
- Ultra-smooth surface enables seamless compatibility with lamination, coating, and printing
- Optional anti-static or anti-slip surface treatments available for customized needs
Product Advantages
Distinguished by its thick 80μm gauge and vivid, consistent red color, this film stands out for easy visual identification in high-volume production lines, reducing sorting inefficiencies. Unlike thinner CPE films, it offers enhanced load-bearing capacity and puncture resistance, minimizing damage during handling and converting. Its premium formulation ensures exceptional batch-to-batch color and thickness consistency, cutting down conversion waste. Non-toxic, odorless, and compliant with global industrial standards, it combines heavy-duty performance with cost-effectiveness, backed by scalable production for steady bulk supply.
Application Environment
Optimized for heavy-duty industrial scenarios, the 80μm red CPE base film excels in thick protective packaging, automotive component wrapping, mechanical part shielding, and colored composite lamination. It performs reliably in dry, normal-temperature environments and moderate low-temperature storage (≥-10℃), maintaining stability during high-speed slitting, lamination, and coating processes. Ideal for manufacturers seeking a visually distinct, heavy-duty base film for industrial end-uses, logistics packaging, and high-demand composite applications requiring enhanced durability and color stability.
