The Purity Paradigm: How High Purity PE Protective Film Maintains Cleanroom Standards

1. Class 100 Cleanroom Production: Manufactured in our ISO-certified facility with HEPA filtration (99.999% efficiency at 0.3μm), minimizing particle generation during extrusion and coating.
2. Low-Extraction Adhesive Technology: Our proprietary acrylic adhesive releases <0.1mg/m² of VOCs (tested via GC-MS), preventing volatile contamination in sterile environments.
3. Anti-Static Nanotexture Surface: Engineered with a surface resistivity of 10⁹-10¹¹ Ω/sq, this layer repels dust particles, validated by particle counter tests (ISO 14644-1 compliant).

Multi-Stage Purity Control Process

• Virgin Material Refinement: PE pellets undergo double-distillation washing to remove trace impurities before extrusion.
• Ultrafiltration Adhesive Filtration: Adhesive is passed through 0.1μm membranes to eliminate micro-particles, ensuring contaminant-free bonding.
• Ionized Air Packaging: Films are sealed in anti-static bags under ionized air, preventing post-production dust adsorption.
• 100% Laser Particle Scanning: Each roll is inspected by laser counters (sensitivity ≥0.3μm) to ensure <0.1 particles/ft² of ≥0.5μm.

Cleanroom Applications Across Industries

• Semiconductor Fabrication: Protecting 300mm wafers, photomasks, and etching equipment from particulate damage.
• Medical Device Sterility: Shielding surgical implants and diagnostic components in ISO 14644-1 class 5 cleanrooms.
