Protection Film for Preventing Leakage of Information, Portable Pouch, Card Case, and Information-Leakage Preventing Plate

摘要

A laminated film (protection film for preventing leakage of information) is laminated on each of base clothes of a portable pouch. The laminated film is formed by lamination of an aluminum foil layer and a resin layer. The portable pouch has the laminated film over the inner surface thereof, whereby electromagnetic wave does not leak outside. That avoids skimming.
