Abstract

PURPOSE: To prepare a double-side mat film excellent in thickness precision with a few processes by a method wherein molten plastics are laminated between two out- side mat films, compressed and then two mat films are separated from the plastic film.
CONSTITUTION: Both sides of a molten plastic film 1 extruded from a T-die head 11 are laminated by two sheets of mat film 2A, 2B and pinched between a cooling roll 12 and a nip roll 13. The surfaces through which the mat films 2A, 2B come in contact with the film 1 have fine indents. Both surfaces of the film 1 pinched between the rolls 12, 13 are forced on to the mat surfaces of the films 2A, 2B so that the indent on the surface is transferred. A double mat film 3 is obtained by separating the films 2A, 2B to both sides after they are cooled.
