What barrier packaging does the desiccant have? Let the editor of Shenzhen Mingwei Industrial Co., Ltd. explain to you: how to use barrier packaging for desiccant. After the desiccant is produced, it needs to be isolated from the air quickly to avoid exposing to the air to absorb a large amount of water vapor and causing failure. Therefore, we use a barrier bag to package the desiccant for storage and transportation, and then open the barrier bag until it is used.

Barrier packaging materials are the key to ensure that the desiccant is still effective after a long period of storage and transportation. In theory, any barrier packaging material has a certain degree of vapor permeability under a certain temperature and humidity, and its index is MoistureVapourTransmissiionRate (MVTR). The unit is: g/m2·day. The higher the water vapor transmission rate, the shorter the storage time of the desiccant; on the contrary, the desiccant can be stored for a longer time. Generally speaking, for the desiccant with short transportation and storage period, we use LDPE barrier bag packaging, and its water vapor transmission rate is 2 g/m2·day (23℃, 85%RH); if the desiccant needs to be stored for a long time For transportation time, it is necessary to strictly follow the DIN55473 standard, and use barrier materials with a water vapor transmission rate of less than 0.5 g/m2·day (23°C, 85% RH) to package the desiccant.

However, we must not ignore the desiccant packaging materials, and there are also strict environmental protection requirements: cartons, packaging boxes, wrapping paper, desiccants, antifungal agents, chopsticks, etc. must not contain prohibited chemicals. At present, it is necessary to protect products from mildew, but also to meet environmental protection standards, and only rely on imported products.
