Topdry In-box Desiccant Pouches


These products absorb moisture inside a smaller closed packaging like a polybag, a box or a pallet.

Typically, in-box desiccants are used for moisture damage prevention when packaging garments and shoes, but also automotive parts, electronic components, pharma, etc.

Small pouches are suitable to protect inside small packaging space when the moisture mainly comes from the goods packed. However, if protecting against moisture in the pallet big enough, then the bigger pack P250 is recommended.

● Topdry desiccants absorb moisture through a water-repellent but breathable film

● Absorbed moisture reacts with starch and turns into a gel that will not leak

● Absorbing agent is calcium chloride of 77% or 94% purity and modified starch

Why choose Topdry In-box Pouches:

● High absorption capacity

● Simple, convenient and effective, strong practicability, wide application scope
