A packaging film is described comprising at least one polymer film layer in which particles of a small-pore or a medium-pore palladium-doped zeolite are dispersed. Such films are of particular utility for the adsorption of volatile organic compounds, such as those originating from organic matter.

A food transportation system and associated modular humidity control system are provided. An example system includes a body configured for attachment with a food storage housing. The body defines a closed circuit air flow path for circulating air through the food storage housing. The system also includes a humidity control element secured within the closed circuit air flow path that condenses moisture from the moisture-laden air passing through the closed circuit air flow path. The system further includes a condensation collector configured to receive fluid condensed from the moisture-laden air by the humidity control element.

A humidity control system includes a two-way humidity control material, a plant extract, and a package housing the two-way humidity control material and the plant extract. A method of flavoring a product and controlling the humidity of an environment in a container includes inserting a humidity control system in the container and enclosing the product in the container. The humidity control system includes a two-way humidity control material, a plant extract, and a package housing the two-way humidity control material and the plant extract.

A humidity control system including: a two-way humidity control material; a substantially pure plant extract blended with the two-way humidity control material to form a mixture; and a package housing the two-way humidity control material and the substantially pure plant extract, wherein the substantially pure plant extract is between about 0.025% and about 5.0% by weight of the mixture.

A vapor-absorbing insert for non-ventilated delivery containers comprising a first and second layers of highly absorbent cotton fiber, and a third absorbent layer (which faces downward toward the food) having an applied layer of adhesive protected by a removable release layer which, when removed, exposes the adhesive for contact with the underside of the lid of a non-ventilated delivery container. The insert is pressed into a continuous laminated composite strip. The several layers may be bonded by pressure-induced interaction between the fibers of adjoining layers, and/or by adhesive fusing at their peripheral edges, and/or by spaced perforations which intertwine fibers between adjoining layers, after which the bonded layers are cut to shape. In use, upon peeling off the peelable anti-stick sheet, the element self-adheres to the underside of the food container lid.

Provided herein is a degassing valve for a consumer product (e.g., a dry foodstuff, a cannabis-containing medicinal or recreational product, etc.) that has an enticing or pleasant aroma. Such a valve includes a valve body, a one-way valve element positioned on the valve body, and, preferably, a filter associated with said valve body wherein the filter is configured to facilitate the passage of a gas. The gas may be selected from the group consisting of air, carbon dioxide, oxygen, nitrogen, and methane, or mixtures thereof. Additionally, the gas contains one or more aroma-conferring volatile molecule species responsible for the aroma characteristic of the product. The filter of the valve body may include activated charcoal, an activated charcoal mixture or a combination thereof. In some embodiments, the consumer product is a dry foodstuff such as flavored or seasoned breadcrumbs, spices, marijuana-containing products, or other flavorful consumer product, the aroma(s) of which can provide an important marketing benefit.
