IN-MOLD DECORATION POLYESTER FILM WITH EXCELLENT MOLDABILITY BY A RANDOM-DIRECTIONAL STRENGTH AND ELONGATION BALANCE AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: An in-mold decoration polyester film is provided to prevent the contamination in a mold and to prevent blocking during a post process and to obtain excellent in-mold moldability by reducing the molding errors of an edge part.;CONSTITUTION: An in-mold decoration polyester film comprises a polyester substrate film and an antistatic layer which is formed on one side of the substrate film and has an elongation deviation(maximum strength - minimum strength) in a film at a random direction of 6 kgf/mm^2 or less. The antistatic layer is formed by spreading an antistatic composition which is formed of 5-40 weight% of a cationic polymer, 0.1-15 weight% of a fluorine-based compound, 1-5 weight% of a particle, 5-20 weight% of a surfactant, and a residual solvent.;COPYRIGHT KIPO 2013
