Abstract
The invention discloses a method for manufacturing an anti-counterfeiting laser positioning film, which comprises the following steps: selecting a PET film as a base material, and coating a varnish coating on the surface of the PET film; compounding the PET film and the anti-counterfeiting grating film, and heating and curing after compounding; step three, rolling the PET film with the pressure intensity of 150N/cm 3 (ii) a Step four, after pressing, feeding the PET film into an oven for heating; and fifthly, carrying out corona treatment on the PET film after drying to obtain the laser positioning film. And an anti-counterfeiting function is added to the laser positioning film by adding the anti-counterfeiting grating film.
Description
Technical Field
The invention belongs to the technical field of laser positioning films, and particularly relates to a manufacturing method of an anti-counterfeiting laser positioning film.
Background
The laser positioning film is popular with consumers due to the three-dimensional effect, has a high-technology anti-counterfeiting function, is generally manufactured in a traditional laser mould pressing mode, generally adopts a direct printing mode to package products, does not have grating anti-counterfeiting and local metal grating anti-counterfeiting effects, and is because most of the existing grating technology is realized by utilizing the high-temperature heat sealing and shaping performances of films, and the characteristics of low-temperature shrink films are just opposite to the performances and are difficult to realize.
Disclosure of Invention
In order to solve the problems in the related art, the application provides a manufacturing method of an anti-counterfeiting laser positioning film, which can improve the strength of a coating.
The technical scheme is as follows:
a manufacturing method of an anti-counterfeiting laser positioning film comprises the following steps:
selecting a PET film as a base material, and coating a varnish coating on the surface of the PET film;
compounding the PET film and the anti-counterfeiting grating film, and heating and curing after compounding;
step three, rolling the PET film with the pressure intensity of 150N/cm 3 ；
Step four, after pressing, feeding the PET film into an oven for heating;
and fifthly, carrying out corona treatment on the PET film after drying to obtain the laser positioning film.
And an anti-counterfeiting function is added to the laser positioning film by adding the anti-counterfeiting grating film.
Further, in the first step, the raw materials of the varnish include ethyl acetate, butyl acetate, propylene glycol and acrylate.
Further, the weight ratio of ethyl acetate, butyl acetate, propylene glycol and acrylate is 2:1:5:7.
further, mixing and heating the raw materials for 15-30min in an electric heating mode.
Further, in the second step, the anti-counterfeiting grating film is a BOPP film, and after compounding, the whole film is shrunk at low temperature and heated and cured.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention as claimed.
Detailed Description
A manufacturing method of an anti-counterfeiting laser positioning film comprises the following steps:
selecting a PET film as a base material, and coating a varnish coating on the surface of the PET film;
compounding the PET film and the anti-counterfeiting grating film, and heating and curing after compounding;
step three, rolling the PET film with the pressure intensity of 150N/cm 3 ；
Fourthly, after pressing, feeding the PET film into a drying oven for heating;
and fifthly, carrying out corona treatment on the PET film after drying to obtain the laser positioning film.
And the anti-counterfeiting function is added to the laser positioning film by adding the anti-counterfeiting grating film.
In the first step, the raw materials of the gloss oil coating comprise ethyl acetate, butyl acetate, propylene glycol and acrylate.
The weight ratio of ethyl acetate, butyl acetate, propylene glycol and acrylate is 2:1:5:7.
mixing the raw materials, heating for 15-30min in an electric heating manner.
In the second step, the anti-counterfeiting grating film is a BOPP film, and after compounding, the whole film is shrunk at low temperature and then heated and cured.
