Abstract

The invention discloses a method for achieving laser effect on common paper, which comprises the following steps of: 1, coating a layer of water-based glue on an OPP laser film by using an anilox roll; 2, pressing the common paper on the OPP laser film coated with the water-based glue by using a wet lamination process; and 3, drying and peeling to form a resin film with stable size, and finally printing or gilding. The method for achieving the laser effect on the common paper does not need vacuum aluminizing equipment or process any more, has low requirement on the paper, can achieve strong laser and printing effects on any common paper, saves energy and reduces consumption to the greatest degree, adopts more environment-friendly materials, is simple and easy to operate, can achieve electrochemical aluminium gilding visual effect and solve the problem that the laser film cannot jump in the traditional method of gilding first and then printing, printing positioning, and cold transfer, is particularly suitable for inner lining paper for cigarette, cork paper bobbins, internal paper, beer marks, medicament packaging boxes, food packaging boxes and the like.

Description

In common paper, realize the method for laser effect

Technical field

The present invention relates to a kind of method that realizes laser effect, particularly relate to a kind of method that realizes laser effect in common paper.

Background technology

The domestic mode that realizes laser effect on paper has two kinds conventionally at present:

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

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

(2) cold transfer~employing OPP laser film is transferred to and on paper, is realized laser effect by UV glue.

The UV glue cost that this technology realizes radium-shine needs is high, and need UV solidification equipment, although OPP laser film can repeat replication laser effect, but UV glue surface can not be realized and again be printed He Hou road processing (as can not be gold stamping), most critical be the difficult problem that cannot solve laser film and can only carry out carrying out by certain step order leapfrog.

Summary of the invention

Technical problem to be solved by this invention is to solve the problem that laser effect cost is high, can not carry out postorder processing that realizes on paper.

In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is to provide a kind of method that realizes laser effect in common paper, comprises the following steps:

Step 1, on OPP laser film, form coating layer, adopt gravure mode, on OPP laser film, be coated with one deck water-based glue by anilox roll;

Step 2, compound, is pressed together on plain paper on the OPP laser film that scribbles water-based glue by wet film coating process;

Step 3, dries and peels off, and first passes through infrared or heated-air drying, and in this process, moisture content, by the lower surface volatilization of paper, is then peeled off paper and OPP laser film layer, forms the resin film of the strong effect of dimensionally stable on paper;

Described water-based glue comprises the component of following mass percent:

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

Waterborne film-forming resin, 34.8%~42.9%;

Defoamer, 0.1%~0.2%;

Levelling agent, 0.1%~0.2%.

In 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 polyethers siloxane copolymers.

Step 4: after step 3 completes, on there is the paper of laser effect, print again or gold stamping or first printing after gold stamping again.

In step 1, in water-based glue, increase the reflecting material with laminated structure, its quality is 5~30% of transfer glue quality.

The described reflecting material with laminated structure is made up of 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 realize strong radium-shine, OPP laser film had both solved PET film can not copy the shortcoming of laser effect again, after having solved again the full version of OPP laser film UV transfer laser effect, can not print again or a gold stamping difficult problem, 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 to greatest extent production cost, be specially adapted to tobacco lining paper, cork paper, inner card board, Beer, medicine packing box, food package box etc.

Brief description of the drawings

Fig. 1 is the paper structure schematic diagram of realizing laser effect that uses the present invention to produce;

Fig. 2 is flow chart of the present invention.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is described in detail.

As shown in Figure 1, utilize the paper with laser effect that the present invention produces to comprise successively from the bottom to top: plain paper layer 1, water-base cement water layer 2, strippable OPP laser film 3, after OPP laser film 3 is peeled off, carry out later process and form printed layers 4 and gold stamping layer 5, wherein in water-base cement water layer 2, uniformly dispersing has some platelet-like reflective materials 6, and platelet-like reflective material 6 is made up of pearl essence, copper bronze, aluminium silver powder or optically variable pigments.

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

Step 1, on OPP laser film, form coating layer, adopt gravure mode, on OPP laser film, be coated with one deck water-based glue by anilox roll;

Step 2, compound, is pressed together on plain paper on the OPP laser film that scribbles water-based glue by wet film coating process;

Step 3, dries and peels off, and first passes through infrared or heated-air drying, and in this process, moisture content, by the lower surface volatilization of paper, is then peeled off paper and OPP laser film layer, forms the resin film of dimensionally stable on paper;

Described water-based glue comprises the component of following mass percent:

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

Waterborne film-forming resin, 34.8%~42.9%;
