Our black conductive PE film is manufactured from carbon-black-loaded polyethylene, providing permanent, volume-conductive ESD protection that is completely independent of ambient humidity. Unlike surface-treated anti-static films that rely on moisture to dissipate charge, the conductive carbon network is uniformly embedded throughout the entire material matrix — ensuring consistent electrical performance over the full product lifetime.
Available in two forms — single/double-wound roll film and seamless tubing — the product is designed for high-volume automated packaging lines, die-cutting operations, and manual packing stations for electrostatic-sensitive devices (ESDs). The tubing format can be cut and heat-sealed to any length on-site, offering maximum flexibility for irregular-shaped components.

Key Features
• Permanent ESD protection — Carbon black is embedded in the PE matrix; conductivity does not degrade over time or with handling
• Humidity independent — Consistent performance from 10% to 90% RH; no moisture required for charge dissipation
• Precisely controlled resistivity — 10⁴–10⁸ Ω/sq covers both conductive and static dissipative grades within the stable production plateau
• Versatile form factors — Roll film (single/double-wound) and seamless tubing for automated or manual packaging
• Custom dimensions — Width up to 1,000mm, thickness 0.05–0.3mm, all to your specification
• Heat-sealable — Compatible with standard impulse and constant-heat sealers (130–170°C)
• Printable surface — ESD warning symbols, part numbers, barcodes, and custom branding
• Compliant — ANSI/ESD S541, IEC 61340-5-3, MIL-PRF-81705, ASTM D257, RoHS, REACH
Applications
• Electronics packaging lines — automated bag-making from tubing
• Die-cutting for custom liners, spacers, and interleaving sheets
• Wafer separator sheets for semiconductor transport
• Tray and box liners for IC trays, JEDEC trays
• PCB board wrapping and cable harness protection
• SMT reel and component packaging
• Field service kits and MRO component storage
