PCT No. PCT/JP96/02023 Sec. 371 Date Jul. 21, 1997 Sec. 102(e) Date Jul. 21, 1997 PCT Filed Jan. 19, 1996 PCT Pub. No. WO97/30115 PCT Pub. Date Aug. 21, 1997Anti-bacterial film according to the present invention is suitable for use as food packaging wrap, and is given with the properties required for such film, such as a clinging property, transparency, and an anti-fogging property, as well as a high anti-bacterial property. The anti-bacterial film according to the present invention comprises, for 100 weight parts of PVC resin, 5 to 50 weight parts of a plasticizer, 0.3 to 3.0 weight parts of a stabilizer, 0.02 to 1.0 weight parts of hydrotalcite, 0.5 to 5.0 weight parts of an anti-fogging agent, and 0.02 to 2.0 weight parts of an anti-bacterial compound. The anti-bacterial compound may consist of a compound obtained by ion exchanging metallic ions of inorganic oxo-acid salt in the form of irregular particles having a particle diameter no more than 0.5 mu m with metallic ions having an anti-bacterial property, or a compound obtained by physically or chemically attaching metallic components having an anti-bacterial property to colloidal particles of inorganic oxides such as SiO2, TiO2, SiO2.Al2O3 and SiO2.B2O3 having a particle diameter no more than 500 nm and forming a colloidal solution. |
