Desiccant masterbatches are additive formulations used in the production of multilayer blown films primarily to address moisture-related issues.

Desiccant masterbatches help maintain the film's quality by preventing issues like surface roughness, voids, bubbles, and fisheyes that can result from the presence of moisture. Films produced with desiccant masterbatches tend to have smoother surfaces and better optical clarity.

Films containing desiccant masterbatches are suitable for packaging hygroscopic materials like chemicals, pharmaceuticals, or sensitive electronic components, as they can maintain the low moisture levels required to prevent product degradation.
