Polyvel is recognized as the leader in fragrance masterbatch technology and has marketed its PolyScent™ product line for over 20 years.

Fragranced plastic is used in toys, air fresheners, film products, odor maskants, advertising promotional items, and other applications. The masterbatches are used in injection molding and film processes as supplied or diluted with virgin resin. Application resins include polyethylene, polypropylene, EVA, polystyrene and flexible PVC.

Fragrance masterbatches are a convenient way to add fragrance to plastic molded parts or films. They are used like a color masterbatches i.e. salt and pepper blends with virgin resin or fed with a separate volumetric or gravimetric feeder.

Pelletized fragrance masterbatches are free flowing pellets. Problems with handling the liquid fragrance are eliminated.
