Only shielding bags form a Faraday cage. Conductive and dissipative packaging prevents charging inside, but does not protect the contents against an external field.

Air cushion bags

ESD Packaging

ESD bubble films and bags combine mechanical protection through air-cushion padding with electrostatic protection. The Warmbier range covers three series: Permastat (3-layer, dissipative, widths 400-1200 mm, 100 m rolls), Carbostat (3-layer, 160 µm, conductive, widths 300-1200 mm) and HIGHSHIELD (shielding, widths 300-1200 mm). This provides solutions for dissipative covering, conductive cushioning and electromagnetically shielded packaging.

⚡ Permastat - dissipative, 3-layer - widths 400 / 600 / 1200 mm, 100 m roll, permanently dissipative air-cushion

✓ Carbostat - conductive, 3-layer, 160 µm - widths 300 / 400 / 1200 mm, 100 m roll, carbon carrier

🛡 HIGHSHIELD - shielding - widths 300 / 400 / 600 / 1200 mm, protects against electromagnetic radiation

📦 Roll goods 100 m - all series as roll stock for machine and manual converting

Series	Layer construction	Thickness	Widths (mm)	ESD class
Permastat 3150	3-layer	-	400 / 600 / 1200	dissipative
Carbostat 3250	3-layer	160 µm	300 / 400 / 1200	conductive
HIGHSHIELD 3350	shielding	-	300 / 400 / 600 / 1200	shielding

Typical applications: Cushioning and ESD protection of PCBs, assemblies and semiconductors during shipment, wrap packaging of sensitive electronics for in-plant transport, shielding MSL-classified components with HIGHSHIELD film against electromagnetic fields, and making custom bags and pouches from roll stock for ESD-sensitive components.
