Title:
DEHUMIDIFICATION BAG AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/243883
Kind Code:
A1
Abstract:
A dehumidification bag and a preparation method therefor. The dehumidification bag comprises: a bag body comprising a first side sheet (7) and a second side sheet (10), wherein the side sheets (7, 10) comprise a breathable film (8) and/or a composite film (11), and all or part of at least one of the side sheets (7, 10) is the breathable film (8); and a moisture-proof layer (12) covering the outer side of the breathable film (8). According to the dehumidification bag, the breathable film (8) is arranged on the bag body, and the outer surface of the breathable film is heat-sealed with the moisture-proof layer (12), so that the breathable film (8) is in close contact with the moisture-proof layer (12) and does not absorb moisture, thereby effectively preventing the breathable film (8) from being in contact with the air in an outer bag during transportation and storage, which result in deterioration or failure of the dehumidifier effect; by setting the moisture-proof layer (12) to be tearable, when the buyer uses it, the buyer only needs to tear off the moisture-proof layer (12), which is convenient and quick.
