Abstract

The invention belongs to the technical field of laser hot stamping, and in particular relates to a 12 μm BOPET film laser hot stamping foil and a preparation method thereof. The 12μm BOPET film laser hot stamping foil includes a layer of 12μm BOPET film substrate, which is coated with a peeling layer, a color layer, a laser molding layer, an aluminum layer, and an adhesive layer in sequence on one side of the substrate. The invention reduces the thickness of the film base material used in laser hot stamping foil, and innovates the technical process and polymer coating formula, which not only saves the use cost of BOPET film, but also has the following advantages: low hot stamping energy consumption, hot stamping Fast speed and good laser effect.

Description

technical field [0001] The invention relates to a 12 μm BOPET film laser hot stamping foil and a preparation method thereof, belonging to the technical field of laser hot stamping. Background technique [0002] The hot stamping graphics and texts of laser hot stamping foil have a unique laser effect, which can improve the appearance of the hot stamping substrate and have a certain anti-counterfeiting effect. It has gradually become popular in various fields in recent years. However, due to the limitations of the existing technology, conventional laser hot stamping foil production generally uses film substrates with a thickness of 15 μm and above, resulting in waste of production materials and a series of problems such as high energy consumption and slow hot stamping speed. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a BOPET film that can save the cost of use, and has: low hot stamping...
