Odor Absorbing Additive Masterbatch for Post-Consumer Plastics Recycling
Masterbatch are used by plastics processors to ensure good dispersion of additives in polymer matrix, especially when additives are needed in low concentration. The additives are pre-dispersed in a resin carrier so that processors can easily let-down into their resin during processing.
Circular economy has become increasingly important, post-consumer plastic packaging wastes are being recycled into new articles. Post-consumer recycled plastics often show a strong smell due to the presence of contaminants or residual contents (e.g. food, detergent, inks, adhesives…) degrading during the recycling process.
Such undesirable smell is usually limiting the amount of recycled plastic that can be used in new plastic articles as affecting consumers’ perception of the product’s and brand’s quality.
