Product Information Page 1 of 1 Issue No 3 No: PIS 174 Date : 12 March 2002 Approved by: MOISTURE BARRIER BAGS Code BW9xx Moisture barrier bags are used to pack IC trays, tubes, and reels of components. The bags are made from a five-layer metalised polyester/polyethylene structure that offers high puncture resistance, high barrier properties and superior vacuum packing performance. The low MVTR of the material results in a reduced desiccant requirement and offers a very good cost/performance relationship for packing moisture sensitive components. Moisture barrier bags meet or exceed the requirements of MIL-B-81705C, EIA 583.
