Fade-resistant Cast Polyethylene Film

High Tensile Strength High Density Polyethylene Film

Product Description

40μm Black Cast Polyethylene (CPE) Base Film

Production Process

Crafted with precision cast extrusion tailored for thin-gauge performance, the 40μm black CPE base film starts with high-grade LDPE resin, homogenously blended with high-concentration, light-fast black masterbatch to ensure uniform opacity and consistent color. The compound is melted in a temperature-regulated extruder (160-180℃) for full fusion, then extruded through a high-precision flat die and cast onto a mirror-polished cooling roller for rapid, controlled solidification. Post-extrusion, precise edge trimming, constant tension calibration, and static neutralization yield tight, defect-free rolls--guaranteeing consistent 40μm gauge, opaque black hue, and a smooth surface ideal for lightweight industrial converting.

Key Features

40μm thin-gauge structure with ±4% thickness tolerance
Opaque black color with exceptional light-blocking capability
Fade-resistant and UV protective properties
Balanced tensile strength and good tear resistance
Excellent flexibility and low-temperature toughness (-10℃ to 60℃)
Ultra-smooth surface for seamless lamination and coating
Optional anti-static treatment available

Product Advantages

Distinguished by its 40μm thin-gauge structure and opaque black color, this film excels in lightweight applications while providing effective light shielding--ideal for products requiring UV protection or privacy. Its thin profile ensures easy processing and cost savings, while the uniform black hue enables quick visual identification in production lines. Exceptional batch-to-batch color and thickness consistency reduces conversion waste, and its cost-effective formulation combines reliable performance with affordability. Non-toxic, odorless, and industry-standard compliant, it supports versatile lightweight converting and steady bulk supply.

Application Environment

Optimized for lightweight industrial scenarios, the 40μm black CPE base film excels in light-blocking industrial packaging, electronic component wrapping, privacy protection films, and lightweight surface protection. It performs reliably in dry, normal-temperature environments and moderate low-temperature storage (≥-10℃), maintaining stability during high-speed slitting, lamination, and coating. Ideal for manufacturers seeking a lightweight, opaque black base film--perfect for applications requiring light shielding, easy processability, and cost-effectiveness, such as electronic part packaging and privacy wrapping.
