<p>PURPOSE:To obtain the title packaging material giving regulative actions for enzyme activation, temperature and humidity and bacteria-removing action, thus suitable for packaging fresh foods by incorporating a thermoplastic with a far-infrared-radiative ceramic comprising specific components. CONSTITUTION:(A) A thermoplastic is incorporated with (B) a far-infrared- radiative ceramic comprising SiO2, Al2O3, MgO, TiO2, Ag2O and Ni2O3, and the resultant composition is put to ion exchange treatment in fresh water and seawater followed by processing into a desired form such as film, bag or container, thus obtaining the objective food packaging material.</p> |
