Sandwich bag with carbon layer

Patent name: A kind of carbon-packed package bag patent applicant Wang Bailang Principal Applicant's address 323300 Huancheng South Road, Miaogao Town, Suichang County, Zhejiang Province Inventor Wang Bailang Application (patent) No. 200420087454.9 Date of application 2004.07.30 Certification Date Audit No. 2752194 Approved Announcement Date 2006.01.18 Instruction CD-ROM D0603-2 Main Classification No. B65D30/08 (2006.01) I Classification No. B65D30/08 (2006.01) I Division Original Application No. Priority Abstracts This application relates to A kind of packaging bag, especially relates to a packaging bag for clothing, fruits, food, metal products, and the like. A bag with a carbon particle layer is composed of a plurality of layers of substrate composites. The multilayer substrate comprises a layer of carbon-containing material layers, and the layer of carbon-containing particles is tightly sealed as a layer of sealing material (2). The outer layer of the material (2) is the fabric layer (1); the layer containing the carbon particle material is in close contact with the inner surface layer (4) of a layer of air-permeable carbon particles. The utility model utilizes a multi-layer substrate to sandwich a carbon particle layer by superimposing or composite processing methods, and is processed into a packaging bag sandwiching a carbon particle layer, the carbon adsorption function of the carbon particle layer is not changed, and the energy is effective. The problem of shedding of carbon particles has been solved and it is relatively easy to realize in actual production. Sovereignty Item 1. A carbon-encapsulating packaging bag composed of a plurality of layers of substrate composites, characterized in that the multi-layer substrate comprises a layer of carbon-containing material layers, and the carbon-containing material layer is layered outwardly as a layer. In the closed material layer (2), the outer layer of the sealing material layer (2) is the fabric layer (1); the layer containing the carbon particle material is in close contact with the inner surface layer (4) in which the air-permeable carbon particles are peeled off.
