In today’s electronics industry, static damage remains one of the most common causes of product failure during storage and transportation. Our ESD shielding bag is designed to safeguard sensitive devices such as PCBs, ICs, and semiconductor components from electrostatic discharge (ESD) and electromagnetic interference (EMI). With multilayer construction and superior static dissipative properties, it is the trusted packaging solution for high-value electronics.

Each metallic shielding bag is engineered with a four-layer structure:

· PET Layer (Polyester) – provides durability and puncture resistance.

· Aluminum Metallization – delivers excellent shielding capability against EMI and ESD events.

· CPP/PE Layer – ensures heat seal strength and flexibility.

· Anti-static Coating – controls surface resistance and prevents charge buildup.

This multilayer design ensures outstanding protection while maintaining a lightweight and flexible packaging solution.

· Surface Resistance: 10⁸–10¹¹ Ω

· Static Decay: <2 seconds

· Shielding Effectiveness: <50 nJ

· Static Voltage Generation: <100V

· Shielding Voltage: ≤30V

· Moisture Barrier: Class 2 (≤5 g/m²·24h)

· Heat Seal Strength: ≥20 N/15mm.

· Reliable Protection – prevents static buildup and direct discharge damage.

· Moisture & Dust Resistance – keeps electronic products safe under harsh conditions.

· Durability & Reusability – strong sealing and resistance against tearing or wear.

· Versatility – available in multiple sizes, thicknesses, and printing options to meet OEM and custom packaging needs.
