Product Description
160μm Brown CPE Base Film
Ultra-heavy-duty brown cast polyethylene base film featuring vivid color, high tensile strength, tear resistance, and puncture-proof construction with smooth surface for lamination compatibility.
Production Process
Manufactured through ultra-precision cast extrusion using high-purity LDPE resin mixed with light-fast brown masterbatch. The process involves controlled melting at 175-195℃, extrusion onto mirror-polished cooling rollers for solidification, followed by trimming, tension control, and winding into defect-free rolls with stable 160μm gauge.
Key Features
- ±4% thickness tolerance with uniform density and stable performance
- Vivid, color-stable brown with excellent light and heat fastness
- Exceptional tensile strength, tear resistance, and puncture resistance
- Good flexibility and low-temperature toughness (-10℃ to 65℃)
- Smooth surface compatible with lamination and coating processes
- Optional anti-static treatment available
Product Advantages
Ultra-heavy-gauge construction provides superior durability and load-bearing capacity compared to thinner alternatives. Uniform brown color enables quick identification and reduces operational inefficiencies. Excellent batch-to-batch consistency minimizes waste while maintaining non-toxic, odorless properties compliant with industry standards.
Application Environment
Ideal for ultra-heavy-duty applications including heavy industrial packaging, large machinery protection, automotive component shielding, and high-demand composite lamination. Maintains stability in dry, normal, or moderate low-temperature environments (≥-10℃) during slitting, lamination, and coating processes.
