MANUFACTURE OF EMBOSS FILM

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method for an emboss film of superior stability in the high speed molding, superior transfer properties for recesses and projections and good surface frost properties. SOLUTION: In a manufacturing method for an emboss film in which thermoplastic resin is melt extruded in the film shape from a lip 11 of a T-die 10 and then an extruded film-shaped material 12 is clamped between an emboss roll 13 and a rubber roll 14 to transfer an emboss pattern of the emboss roll. 13 onto the surface of the material, a liquid film is formed on the rubber roll 14 on the position whereon both ends of the film-shaped extruded material 12 are brought into contact with.
