Iridescent film with multidirectional variable optical stripes, including multiple very thin laminated films. The films are respectively made of different transparent plastic materials with different refractive indices. At least one surface of the laminated films has numerous different stripes with different directions or pitches. When seen in different directions, the stripes of the iridescent film can reflect different colors and shapes of bright stripes. In addition, very fine bright colorful points are evenly distributed in the stripes to create a unique and tender vision.
