ESD Shielding Bags: Ultimate Protection for Sensitive Electronics
Core Product Advantages
1. Dual Protection Performance: Integrates static dissipation and EMI shielding functions. The outer and inner electrostatic dissipative layers quickly release accumulated charges, keeping surface voltage below 100V; the middle aluminum metallization layer adopts Faraday cage principle, with a resistance of less than 100Ω (meeting international standards), effectively blocking 70% of external electromagnetic waves and reducing interference intensity to 1/1000.
2. Superior Material & Structure: Adopts multi-layer composite structure (PET + Aluminum Metallization + CPP/CPE + Anti-static Coating). PET layer enhances durability and puncture resistance, CPP/CPE layer ensures strong heat sealing and flexibility, and the overall design achieves excellent tensile strength (>18 lbs/inch) and moisture barrier performance (<0.2 g/100 sq.in/24h).
3. Practical & Versatile Design: Silver-gray translucent appearance allows easy identification of internal items and barcode scanning without opening the bag. Available in flat bags, self-sealing bags, and zipper bags, with customizable thickness (75μm-120μm) to meet different packaging needs.
4. Compliance & Reliability: Fully complies with ROHS standards and passes strict international tests (ASTM D257, EIA 541, etc.). Static decay time is less than 0.03 seconds, and shielding effectiveness is less than 15 nJ, ensuring stable protection for sensitive components.
