Abstract
An anti-static package composed of a multiply flexible film. The inner ply is an anti-static material and the outer ply is an electrically insulating material. A conductive metallic ply is sandwiched between the inner and outer ply. The conductive material is sputtered onto one of the two plies and the other ply is bonded by an adhesive bond to the metal ply.
Claims20
A package adapted to receive and protect an electronic component, the walls of the package formed of a flexible sheet material comprising:
- a first ply of an electrically insulating material,
- a second ply of a conductive material, and
- a third ply of an anti-static material,
- said second ply being embedded on the surface of one of said first or third plies and the other one of said first or third plies being bonded to said conductive second ply,
- said conductive second ply composed of a material providing a surface resistivity no greater than approximately 5.times.10.sup.4 ohms per square and being sufficiently transparent to permit visual identification of a component through the envelope,
- said conductive second ply being sandwiched between said first and third plies.
