Desiccant masterbatch contains moisture-absorbing agents, such as calcium oxide (CaO) or silica gel, which can effectively absorb moisture from the surrounding environment. In mulch films, which are typically used in outdoor agricultural settings, moisture can be a concern as it may lead to the growth of mold, mildew, or the deterioration of the film itself. Desiccant masterbatch helps prevent these issues by absorbing moisture that comes into contact with the film.

In agricultural settings, mulch films are often stored in rolls or sheets. Moisture can cause the mulch film to stick together, making it challenging to handle and apply. Desiccant masterbatch helps prevent clumping and agglomeration, ensuring that the mulch film remains easy to work with.

Mulch films are often stored for extended periods before use. Desiccant masterbatch can help extend the shelf life of these films by preventing moisture-related degradation during storage.
