Packaging materials and methods for their preparation and use

Details of the Patent
Temperature control systems for packaging can help to maintain food quality. Refrigerated or cooled food items with non-ideal packaging that are transported between cold storage locations or not refrigerated by customers in a timely fashion would benefit from better insulation for storage, transport and post-purchase handling. Likewise, a self-heating packaging may allow a consumer to conveniently enjoy food that is meant to be heated. As such, there is a need for food packaging solutions that improve the quality of food as compared with standard packaging. Embodiments disclosed in this document are directed to packaging having at least one agent disposed within a shape memory polymer which is adapted to release the agent in response to a stimulus. Such packaging may be configured, for example, to hold food or beverages. Such packaging may be used, for example, to detect environmental conditions during transport or storage, maintain a temperature of the food to preserve food quality, or provide a pleasant sensory experience to a consumer.
