Abstract: Packaging materials may include a packaging material formed from an intelligent polymer composition, wherein the intelligent polymer composition includes a matrix polymer and an indicator, wherein the indicator triggers a color change in the intelligent polymeric composition when exposed to an external stimulus, and wherein the intelligent polymer composition is configured to contact a material enclosed within the packaging material. Methods may include forming a packaging material from an intelligent polymer composition, wherein the intelligent polymer composition includes a matrix polymer and an indicator, wherein the indicator triggers a color change in the intelligent polymeric composition when exposed to an external stimulus, and wherein the intelligent polymer composition is configured to contact a material enclosed within the packaging material.
