A foamable polymeric composition can comprise a polymer, a blowing agent cage material, and a blowing agent. The blowing agent cage material is selected from the group consisting of zeolite imidazolate framework, metal organic framework, carbon cage structure, and combinations comprising at least one of the foregoing. In one embodiment, the composition can be formed by mixing the polymer with the blowing agent cage material to form a mixture, introducing a blowing agent to the mixture, and forming the mixture into pellets.
