Abstract
A zeolite formulation has been identified that is to be included in an arrangement of barrier layers allowing for the entrapment of volatile organoleptic compound (VOCs), in particular, odor causing VOCs, between the barrier layers in order to contain the release of these compounds. The entrapment technique allows for extended time to adsorb, absorb or react such VOCs before they can be absorbed by the product surrounded by the packaging. A zeolite formulation of an odor scavenger layer not having any VOC barrier layers within the film is also disclosed having the capability to contain the release of hydrogen sulfide over a period of at least 20 days.
