Abstract
A method of shrinking a film comprises the steps of providing a shrink film and exposing the film to an amount of radiation energy effective to activate the shrink characteristic of the film. The film comprises one or more thermoplastic polymers and at least about 0.001 weight % of single-walled carbon nanotube material based on the weight of the film.
