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

Realize the method for laser effect in common paper

Technical field

The present invention relates to a kind of method that realizes laser effect, particularly relate to a kind of method at common paper realization laser effect, can realize full version or local laser effect according to actual needs.

Background technology

At present domestic mode at paper realization laser effect has two kinds usually:

(1), being coated with transfer layer at the PET film transfers to paper again by mold pressing, after vacuum aluminum-coated and realizes laser effect.

This technology realizes effect consuming cost height, and process route is long, and the equipment that technology realizes requires height, needs the vacuum aluminum-plating equipment of purchasing price costliness, and PET film repeat replication laser effect again.

(2) cold transfer is adopted the radium-shine film of OPP to transfer to by UV glue and is realized laser effect on the paper.

This technology realizes the UV glue cost height of radium-shine needs, and need the UV solidification equipment, but though the radium-shine film repeat replication of OPP laser effect, but UV glue surface can not realize printing again and back road processing (as can not be gold stamping), most critical be to solve the difficult problem that radium-shine film can only carry out carrying out leapfrog by the certain step order.

Summary of the invention

Technical problem to be solved by this invention is to solve at paper to need could realize full version or local laser effect, can not carry out the problem that the processing of road, back is handled at paper through traditional gilding technology.Can replace traditional vacuum from the technical standpoint fully aluminizes and shifts paper and cold wave technology.

In order to solve the problems of the technologies described above, the technical solution adopted in the present invention provides a kind of method at common paper realization laser effect, may further comprise the steps:

Step 1, at the radium-shine film of OPP coating one deck peel ply, described peel ply is formed by acetylbutyrylcellulose or polymethyl methacrylate;

Step 2, on peel ply printing word or pattern;

Step 3, the radium-shine film of the OPP after printing adopt the gravure mode, cover peel ply by anilox roll coating one deck water-based glue;

Step 4, compound namely is pressed together on plain paper on the radium-shine film of the OPP that scribbles water-based glue by wet film coating process;

Step 5 is dried and is peeled off, and namely at first passes through infrared or heated-air drying, and moisture content is peeled off paper and the radium-shine thin layer of OPP then by the lower surface volatilization of paper in this process, forms the resin film of dimensionally stable at paper;

Described water-based glue comprises following component by mass percent:

Strippable water-base resin, 56.9%~64.8%;

The waterborne film-forming resin, 34.8%~42.9%;

Defoamer, 0.1%~0.2%;

Levelling agent, 0.1%~0.2%.

In the such scheme, described strippable water-base resin is the copolymer of styrene and methyl methacrylate or butyl methacrylate.

Described waterborne film-forming resin is the copolymer of water soluble acrylic acid methyl esters and butyl acrylate.

Described defoamer is polysiloxane-polyether copolymer.

Described levelling agent is the polyethers siloxane copolymers.

Literal or pattern adopt full version or local printing in the step 2.

Further, after step 5 is finished, on have the paper of laser effect, can also print after the gold stamping or first printing gold stamping more again.

In the step 3, increase the reflecting material with laminated structure in water-based glue, its quality is 5~30% of transfer glue quality.

Described reflecting material with laminated structure is made by pearl essence, copper bronze, aluminium silver powder or optically variable pigments.

The present invention does not need vacuum aluminium plating process, to paper require low, on any plain paper, can both realize strong radium-shine, the radium-shine film of OPP had both solved the shortcoming that the PET film can not copy laser effect again, can not print again or a gold stamping difficult problem after having solved the full version of the radium-shine film of OPP UV transfer laser effect again, and can realize local laser and printing, not only can reach electrochemical aluminium gold-stamped visual effect, can also solve traditional first ironing and then printing, printing location and cold transfer laser film can not leapfrog a difficult problem, paper in low grammes per square metre is realized laser effect, save production cost to greatest extent, be specially adapted to tobacco lining paper, yew paper, inner card board, the beer mark, medicine packing box, food package box etc.

Description of drawings

Fig. 1 is the paper structure schematic diagram of the realization laser effect of use the present invention production;

Fig. 2 is flow chart of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is made detailed explanation.

As shown in Figure 1, the paper with laser effect that utilizes the present invention to produce comprises from the bottom to top successively: uniformly dispersing has some platelet-like reflective materials 8 in plain paper layer 1, water-base cement water layer 2, literal or patterned layer 3, peel ply 4, the radium-shine film 7 of strippable OPP, the water-base cement water layer 2, and platelet-like reflective material 8 is made by pearl essence, copper bronze, aluminium silver powder or optically variable pigments.

As shown in Figure 2, the present invention includes following steps:

Step 1, at the radium-shine film of OPP coating one deck peel ply, described peel ply is formed by acetylbutyrylcellulose or polymethyl methacrylate;

Step 2, on peel ply printing word or pattern;

Step 3, the radium-shine film of the OPP after printing adopt the gravure mode, cover whole peel ply by anilox roll coating one deck water-based glue;

Step 4, compound namely is pressed together on plain paper on the radium-shine film of the OPP that scribbles water-based glue by wet film coating process;

Step 5 is dried and is peeled off, and namely at first passes through infrared or heated-air drying, and moisture content is peeled off paper and the radium-shine thin layer of OPP then by the lower surface volatilization of paper in this process, and the literal on paper and pattern present strong laser effect;

Described water-based glue comprises following component by mass percent:

Strippable water-base resin, 56.9%~64.8%;
