Embodiment 1

[0048] The present invention comprises the component of following mass percentage:

[0049] Strippable styrene-methyl methacrylate copolymer water-based resin, 56.9%;

[0050] Copolymerized film-forming resin of waterborne methyl acrylate and butyl acrylate, 42.9%;

[0051] Polysiloxane-polyether copolymer defoamer, 0.1%;

[0052] Polyetheroxane wetting and leveling agent, 0.1%.

Embodiment 2

[0054] Strippable styrene and butyl methacrylate copolymer water-based resin, 64.8%;

[0055] Copolymerized film-forming resin of waterborne methyl acrylate and butyl acrylate, 34.8%;

[0056] Polysiloxane-polyether copolymer defoamer, 0.2%;

[0057] Polyetheroxane wetting and leveling agent, 0.2%.

Embodiment 3

[0059] Strippable styrene-butyl methacrylate copolymer water-based resin, 58.3%;

[0060] Copolymerized film-forming resin of waterborne methyl acrylate and butyl acrylate, 41.4%;

[0061] Polysiloxane-polyether copolymer defoamer, 0.15%;

[0062] Polyetheroxane wetting and leveling agent, 0.15%.

[0063] Water-based glue in the present invention has the following advantages:

[0064] First, the OPP laser film on it is easy to peel off;

[0065] Second, it has a good binding force to the paper under it;

[0066] Third, flake reflective materials can be added to enhance the laser effect;

[0067] Fourth, it has good flexibility and moderate hardness, which can prevent shedding and napping caused by multiple printings;

[0068] Fifth, the water-based glue has good dimensional stability after drying and curing, which can ensure a strong laser effect;

[0069] Sixth, the water-based glue has good printing adaptability after film formation.

Abstract

The invention discloses a method for realizing laser effect on common paper. The method can realize full or local effect according to the actual requirement and comprises the following steps of: coating a stripping layer on an OPP laser film; printing characters or patterns fully or locally on the stripping layer; coating a layer of water-based glue on the OPP laser film; stitching the common paper on the OPP laser film coated with the water-based glue by a wet film coating process; and finally drying and stripping, so that the characters or patterns on the paper shows strong laser effect. The method realizes the laser effect on the paper without a vacuum aluminum plating process, has low requirement on the paper, and can not only achieve the visual effect of electrochemical aluminum gilding, but also can solve the problem of the conventional first hot printing process that the steps of printing positioning and cold transfer of the laser film cannot be leapfrogged; and besides, energyis saved and consumption is reduced to the greatest degree, the material is more environmental-friendly, the operation is simple and easy, and the method is particularly applicable to internal liningpaper for cigarettes, tipping paper, internal paper, beer labels, medicine packaging boxes, food packaging boxes and the like.

Description

technical field [0001] The invention relates to a method for realizing laser effects, in particular to a method for realizing laser effects on ordinary paper, which can realize full-page or partial laser effects according to actual needs. Background technique [0002] At present, there are usually two ways to achieve laser effects on paper in China: [0003] (1) Coat the transfer layer on the PET film and then transfer it to the paper to achieve the laser effect through molding and vacuum aluminum plating. [0004] The effect of this technology consumes high cost, long process route, and high equipment requirements for process realization. It is necessary to purchase expensive vacuum aluminum plating equipment, and the PET film cannot repeat the laser effect again. [0005] (2) Cold transfer, using OPP laser film to transfer to paper through UV glue to achieve laser effect. [0006] The cost of UV glue required by this technology to achieve laser is high, and a UV curing d...
