A thermoplastic polyurethane (PU) polymer was synthesized, casted into films, and specific and overall migration (OM) tests were applied. A new method with gas chromatography–flame ionization detector was proposed to measure specific migration (SM) of 1,4‐butanediol from the PU film. OM values in the four established simulants were under the legal limits. Determination of 1,4‐butanediol migrating from PU film to the three established simulants showed maximum SM result as 1.5 mg/kg which was far below the legal limits. Therefore, the PU film has a good potential as a safe food contact material. Moreover, the analytical method used for determination of SM of 1,4‐butanediol resulted in good analytical characteristics and detection limits at ppm level. © 2019 Wiley Periodicals, Inc. J. Appl.
