摘要
Heat sealable food packaging films, methods for the production thereof, and food packages comprising heat sealable food packaging films are provided. The heat sealable food packaging film includes a humidity-dependent permeable film having a moisture vapor transmission rate that increases with an increase in relative humidity (RH). An outer coating comprises a coating material on at least one surface of the humidity-dependent permeable film. The coating material is selected from a nanoclay dispersed in a poly-vinylidene chloride (PVdC) polymer or a stretchable urethane polymer, a stretchable acrylic polymer, or a combination of stretchable urethane polymer and stretchable acrylic polymer. The coating material may further comprise an anti-blocking agent. The heat sealable food packaging film is biaxially oriented.
