PROBLEM TO BE SOLVED: To improve the self-adhesive force of a multicomponent film by allowing a temperature-controlled radiation transmissible material for the multicomponent film to be present in a single layer or plural layers entirely encircled by a transparent crystal layer. SOLUTION: The temperature-controlled radiation transmissible material for a multicomponent film is present in a single layer or plural layers entirely encircled by a transparent crustal layer. A core material to be used is selected from thermally oriented polymers and the components of the polymer blend show a lower critical separation temperature which is known to be generated when it is the case with a polymer blend indicating an interference of a middle scale due to a mechanism such as salt formation, hydrogen bonding, complexing, p-electronic interference or amphoteric ionic interference. The thermally oriented polymer blend and a crustal polymer are supplied to a die suited for manufacturing a composite compound film, in a molten state, passing through an extruding machine. The core has a circular section when it is in the simplest form. |
