FILM AND METHOD FOR PRODUCTION THEREOF

Disclosed is a film which is knurling-processed without the fracture of the film. Also disclosed is a method for producing the film. The film comprises a polymer resin film, in which a knurling processing is applied on both end parts in the width-wise direction on at least one surface of the film by...

Beschreibung
Zusammenfassung:	Disclosed is a film which is knurling-processed without the fracture of the film. Also disclosed is a method for producing the film. The film comprises a polymer resin film, in which a knurling processing is applied on both end parts in the width-wise direction on at least one surface of the film by irradiating the film with a laser beam. L'invention porte sur un film qui est traité par moletage sans fracture du film. L'invention porte également sur un procédé de fabrication du film. Le film comporte un film de résine polymère, dans lequel un traitement de moletage est appliqué sur les deux parties d'extrémité dans la direction de la largeur sur au moins une surface du film par l'irradiation du film par un faisceau laser.
