The invention discloses a laser-molded polyester film, and mainly relates to the field of polyester film. It includes a molding layer, a film base layer, and a coating layer in turn; the resin used in the molding layer is a mixture of modified resin A and modified polyester B, and the modified resin A is 1,4-butanediol and The polyester modified material of phthalic acid; the modified polyester B is a polyester modified material modified by isophthalic acid and 1,4-cyclohexanedimethanol; the coating layer is made of acrylic coating. The mixture of layer material and polyester type coating material, and add isocyanate type crosslinking agent for crosslinking. The beneficial effects of the present invention are as follows: the problems of complex laser process, high cost and pollution exist in thin film implementation, and the film of the present application can be directly molded and printed with UV ink, which reduces the laser printing process, saves time and effort, and reduces pollution. |
