Shielding bag

Abstract

The invention discloses a shielding bag. A bag body is formed by two shielding materials in a three-side hot sealing manner or is formed by hot sealing double sides of a folded shielding material; a bag opening of the bag body is sealed through a sealing opening; the shielding material comprises a transparent substrate, an inner layer and a shielding metal layer; the transparent substrate and the inner layer are mutually adhered; and the shielding metal layer is coated on one side of the inner layer. According to the shielding bag disclosed by the invention, the bag body has the certain electrostatic discharge function, the transparent substrate and the inner layer are mutually adhered together, the shielding metal layer is coated on the inner side of the inner layer, and the shielding metal layer has the great shielding function; therefore when a package material formed by combining the transparent substrate, the inner layer and the shielding metal layer is used for packing an electronic element, the static electricity can be greatly eliminated, the generation of enormous economic loss caused by the fact that the electronic element is damaged by the static electricity is avoided; and the transparency of the transparent substrate is high, and the electronic element in the shielding bag is conveniently observed.

Description

technical field [0001] The invention relates to a shielding bag, in particular to a shielding bag used for packaging electronic components. Background technique [0002] Static electricity is a common and complex physical phenomenon. With the rapid development of science and technology, the high efficiency and automation of production, and the widespread use of electronic equipment such as communications and radar, the static and electromagnetic environment is getting worse. It poses a threat to products such as electronic components that are sensitive to static electricity and electromagnetic radiation. When static electricity accumulates to a certain extent and encounters suitable conditions, various disadvantages will occur. For electrostatic sensitive devices such as electronic components; If a material that is prone to static electricity is used as the packaging bag, the accumulation of static electricity due to friction or electromagnetic induction will generate discha...

[0002] Static electricity is a common and complex physical phenomenon. With the rapid development of science and technology, the high efficiency and automation of production, and the widespread use of electronic equipment such as communications and radar, the static and electromagnetic environment is getting worse. It poses a threat to products such as electronic components that are sensitive to static electricity and electromagnetic radiation. When static electricity accumulates to a certain extent and encounters suitable conditions, various disadvantages will occur. For electrostatic sensitive devices such as electronic components; If a material that is prone to static electricity is used as the packaging bag, the static electricity accumulated due to friction or electromagnetic induction will generate discharge under suitable conditions, causing product failure or damage to some components, resulting in great economic losses
