Abstract: Provided herein are blown films with encapsulated active agents, such as volatile anti-microbial agents, suitable for use as food packaging materials. Also provided herein are methods of manufacturing such blown films. The methods include extruding a bubble from molten polymers, dispensing active agents inside the bubble, and collapsing the bubble such that the bubble self-adheres to form a film with the active agents encapsulated.

Abstract: Provided herein are packaging systems suitable for storing products, such as food products. The packaging systems are made up of multilayer film constructions that provide controlled release of an active agent at a point in time that is past the manufacturing of the packaging systems but coincides with their functional use (e.g., at the food packaging step). The multilayer film constructions have a composition that is sensitive to humidity, which converts the constructions from a barrier to a transmitter of the active agent loaded within multilayer film constructions.

Abstract: Provided herein are laminated films with active agents, such as volatile anti-microbial agents, suitable for use as food packaging materials. Also provided herein are bags made from such laminated films, as well as methods of manufacturing such laminated films.
