Embodiment Construction

[0034] A production process for positioning hot film, comprising a PET base film, on which a release layer, a coloring layer, a vacuum aluminized layer and an adhesive layer are sequentially arranged on the PET base film from the inside to the outside;

[0035] Described release layer comprises toluene and butanone, and the mass ratio of toluene and butanone is 7:3, by setting the mass ratio of energy toluene and butanone, the release layer coated on the PET base film has the best Excellent detachability, can transfer the coating on the hot stamping material to the surface of the hot stamping material well and completely, ensuring that the coating is not damaged;

[0036] The colored layer comprises the following components: 20-40 parts by weight of nitrocellulose, 20-30 parts by weight of ethyl acetate, 10-15 parts by weight of n-propyl acetate and 2-4 parts by weight of pigments. Set the weight of different components to control the color, brightness, trimming, flexibility, ...

Abstract

The invention relates to a production process for a positioning stamping film comprising a PET base film; the PET base film is successively provided with a release layer, a coloring layer, a vacuum aluminum plating layer and a back glue layer from inside to outside. The production process comprises the following steps successively: mixing of a release layer coating, coating of a release layer, mixing of a coloring layer coating, coating of a coloring layer, mold pressing, vacuum aluminizing, aluminum washing, zinc sulfide coating, mixing of a back glue layer coating, back glue layer coating, slitting, and quality inspection. The production process has the advantages that the positioning stamping film produced by the steps has the advantages of high technical content and strong secrecy, isnon-duplicated, and can give consumers direct visual observation discrimination of authenticity before purchasing in goods anti-counterfeiting aspect, the packaging is prevented from being reused by counterfeiters, and the anti-counterfeiting performance and commercial benefits are improved; the produced positioning stamping film eliminates the gradual accumulation of stamping accuracy error in astamping process, and an independent pattern stamping foil needs a positioning cursor to correct the error of holographic patterns at intervals in time.

Description

technical field [0001] The invention relates to a production process for positioning hot film. Background technique [0002] The positioning technology is mainly to eliminate the gradual accumulation of hot stamping accuracy errors during the hot stamping process. The independent pattern hot stamping foil needs to use the positioning cursor to correct the error in the spacing of the holographic pattern in time. The holographic pattern on each hot stamping foil needs to have a matching square cursor. The holographic pattern is consistent with the center line of the cursor, and the distance between the holographic pattern and the cursor is maintained at a constant relative position of at least 3 mm. To ensure the accuracy of the cursor, the edge of the cursor It should be very straight, with sharp and consistent optical characteristics, but the following problems are prone to occur in the production process of the existing positioning foil: 1. The existing holographic anti-cou...
