Deodorizing masterbatches are functional masterbatches formulated using polyolefins as a carrier, blended with highly effective adsorbent and reactive deodorizing additives as well as dispersants. They are primarily used to adsorb, neutralize, or decompose odors, VOCs, and irritating odors generated by films and packaging contents. When added, these masterbatches effectively reduce residual resin odors and processing odors, enhancing film purity and safety. They are particularly suitable for odor-sensitive applications such as food packaging and consumer goods packaging. Compatible with various film substrates including PE, PP, and CPP, they do not affect film transparency, heat sealability, or processing performance. With low dosage requirements, stable dispersion, and long-lasting effects, these masterbatches are essential for improving the environmental performance of films and enhancing the packaging experience.
