DEHUMIDIFICATION BAG AND PREPARATION METHOD THEREOF

The present invention relates to a dehumidification bag and a preparation method thereof. The dehumidification bag comprises a bag body including a first side sheet and a second side sheet, the side sheet comprises an air-permeability and/or a composite film, wherein at least all or part of at least one side sheet is an air-permeability film; a moisture-proof layer covers the outside of the air-permeability. The dehumidification bag provided by the present invention provides an air-permeability on the bag body, and adopts heat sealing between the outer surface of the air-permeability layer and the moisture-proof layer, so that the air-permeability and the moisture-proof layer are in close contact without moisture absorption, which effectively prevents damage during transportation and storage. In the process, the air-permeability is in contact with the air in the outer bag and the effect of the dehumidifier becomes poor or invalid; by setting the moisture-proof layer to be tearable, when the buyer uses the dehumidification bag, the moisture-proof layer can be torn off, which is convenient and fast.
