    摘要: A white film to be laminated to a metal surface and a method of producing the same. This white film comprises first and second layers which are laminated with the arrangement of second layer/first layer/second layer. The middle, first layer is composed of 80-40 wt % a first polyester, and 20-60 wt % titanium oxide added therewith. The front and back, second layers are composed of 80-100 wt % a second polyester, and 20-0 wt % titanium oxide. The film is a biaxially stretched film, and the content of titanium oxide in the entire film is 20-50 wt %.
