Abstract

Techniques and technologies are generally described herein for providing shape memory polymer packaging for meat products from sheets or films of shape memory polymer material. Shape memory polymers are a class of smart materials which have the ability to return to their original or trained state from a deformed or temporary state when a stimulus is provided. The stimulus is typically a temperature change. The stimulus may also be exposure to an electric or magnetic field, exposure to light, or even exposure to a particular atmosphere, e.g., water. Shape memory polymers now include many materials, including both thermoplastic materials and thermoset materials (covalently cross-linked). The memory effect of the shape memory polymer is used to shape a meat product and to make the meat product more attractive to a consumer.
