Abstract
The present disclosure relates to a thermoplastic film that includes dual fragrance odor control. For example, the thermoplastic can film include a first fragrance component, such as a neat oil applied directly thereon. The thermoplastic film can also include an encapsulated fragrance component applied thereon. The encapsulated fragrance component can include a fragrance encapsulated within a plurality of encapsulants and can be configured to delay a release of the fragrance, such as until there is a physical interaction applied to the thermoplastic film.
