Abstract
The present disclosure relates to a thermoplastic film that includes a plurality of ribs and a plurality of web areas that separate and connect the ribs. The thermoplastic film further includes an encapsulated odor control component that includes an odor control active encapsulated within a plurality of encapsulants. The encapsulants can be configured to delay a release of the odor-control active until activated. Further, the encapsulated odor control component can be applied across the plurality of ribs and the plurality of web areas, which can be configured to cause the encapsulants to activate in phases.
