Post-consumer recycled plastics often exhibit a strong smell due to the presence of contaminants or residual contents, such as food, detergent, inks and adhesives, that degrade during the recycling process. Undesirable smells limit the amount of recycled plastic that can be used in new plastic items, as they affect consumer perceptions of product and brand quality.
Ampacet has extended the OdorClear™ range of odour-absorbing masterbatches. Originally introduced as Odour Scavenger, the newly-expanded range of powerful wide-spectrum masterbatches minimizes odors of post-consumer recycled materials and keeps them enclosed inside the polymer, which allows converters to boost content of recycled material in packaging. OdorClear outperforms conventional inorganic odor scavenging solutions, enabling increased use of post-consumer resins to support the circular economy. OdorClear masterbatches are designed for use with a broad range of recycled polymers and can be specially formulated for injection and blow molding, film and other extrusion processes.
Ampacet OdorClear also can be used in combination with other Ampacet R3 Sustainable Solutions products, including ThermProtect™, BlueEdge™ and ReVive™, to minimize issues such as thermal degradation, inconsistent color or product uniformity that may occur with the use of high quantities of recycled material.
