POLYAMIDE MATTE FILM CONSISTS OF MULTI-LAYER STRUCTURE HAVING IMPROVED PRINTING PROPERTY AND METHOD FOR PREPARING THE SAME

摘要

The present invention relates to a polyamide matte film comprising, for example, a matte layer (A layer), a substrate layer (B layer) made of a polyamide resin and a printing layer (C layer), wherein the matte layer (non-glossy layer, A layer) has 40% or less of a haze and 20% or more of a glossiness, the substrate layer (B layer) consists of a polyamide resin, and a weight ratio between a polyamide-based resin and a silica is 99.99/0.01 to 99.95/0.05. According to the present invention, the polyamide matte film having a multi-layered structure comprises a matte layer (A layer), a substrate layer (B layer) made of a polyamide resin and a printing layer (C layer). The invention comprises: the matte layer (non-glossy layer, A layer) having 40% or less of a haze and 20% or more of a glossiness, the substrate layer (B layer) made of a polyamide resin; and the printing layer (C layer) having 99.99/0.01 to 99.95/0.05 as a weight ratio between a polyamide-based resin and a silica.
