DESCO D301618 Dri-Shield 3000 moisture barrier bag
The DESCO D301618 is a moisture barrier bag for electronics, where both moisture and ESD need to be controlled. It is typically used for sensitive SMT components and other items that cannot tolerate standard packaging. The bag is constructed as a laminate bag with layers of nylon, foil, and polyethylene, providing both mechanical strength and an effective barrier against moisture.
It is precisely this combination that makes this type relevant in professional electronics packaging. The foil layer contributes to shielding against electrostatic discharges, while the very low MVTR value indicates that moisture has difficulty penetrating. The bag is also heat-sealable and suitable for vacuum packing when the packaging needs to be tight and controlled.
The surfaces are dissipative both internally and externally, and the bag is printed with an ESD warning symbol and moisture-sensitive marking, as well as a lot code for traceability. In practice, this makes it suitable when packaging, storing, or shipping electronics in conditions where both static electricity and moisture can cause problems.
As with other dry packing of electronics, it is normally used together with desiccant and a humidity indicator card to monitor the moisture level in the package.
Typical applications
- Packaging of ESD-sensitive and moisture-sensitive electronic components
- Packing of SMT items for storage and transport
