SCS ESD shielding and moisture barrier bag, 203 x 255 mm, film thickness 0.178 mm - Desco D27810

Moisture-sensitive components and circuit boards face two risks in storage and shipping: absorbed humidity and electrostatic discharge. This moisture barrier bag in 203 x 255 mm covers both. The multilayer film of polyester, aluminium and polyethylene, 0.1778 mm (7 mil) ±10 % thick, has a defined water vapour transmission rate, and the shielding limits the discharge energy that passes through to less than 10 nJ.

Benefits

• Aluminium layer inside the polyester, aluminium and polyethylene laminate, film thickness 0.1778 mm (7 mil): the heavier-gauge version with a metallic barrier layer against moisture.
• Shielding against ESD and interference: shielding value less than 10 nJ, EMI attenuation above 40 dB.
• Surface resistance inside and outside below 10E11 Ohm each, so the bag does not charge up during filling and handling.
• Heat-sealable and suitable for vacuum packing: close the bag airtight after filling, evacuate first if required.
• Compliant with EN 61340-5-1 and RoHS, with a printed ESD warning symbol that marks the content at goods receipt.

Applications

At 203 x 255 mm the bag takes single modules, small printed circuit boards and trays of moisture-sensitive ICs. It is used to store components between two production steps and to ship small assemblies, with desiccant and a humidity indicator card sealed in with the parts. The range is also available in other sizes.
