Title:
METHOD FOR FORMING ELECTROSTATIC SHIELDING BAG
Document Type and Number:
Japanese Patent JPH04339783
Kind Code:
A
Abstract:
PURPOSE: To form a bag by the conventional bag forming machine without impairing the electrostatic shielding performance.
CONSTITUTION: A medthod for producing an electrostatic shielding bag which comprises producing a multilayer sheet having an electric conducting layer with a surface resistivity of at most 108Ω/square formed on the outer surface of an insulating base film 1 and an antistatic layer with a surface resistivity of at most 1012Ω/square formed on the inner surface thereof; folding the sheet with the electric conducting layer outward; and slitting the folded part thereof partially to form a slit 4 as a receiving opening.
