The utility model discloses accessible laser burns and carves out pattern and characters to bearing paper, in addition the utility model discloses an accessible laser can keep out laser for laser can not cause destruction to metal level and bottom paper, makes the utility model discloses wholly can not form hollow out construction after laser engraving, thereby guarantee the utility model discloses an overall strength.

Description

Laser engraving paper

Technical Field

The utility model relates to the technical field of packaging, especially indicate a laser engraving paper.

Background

A plurality of commodities need to be packaged by packaging paper, and the packaging paper needs to be provided with patterns and characters to play a role in beautifying and marking. At present, most of patterns and characters on the packaging paper are printed on the packaging paper by adopting a plane printing process, but the patterns and characters printed by adopting the plane printing process have no stereoscopic impression, have poor impression on users, and have higher cost when printed in small batches; therefore, patterns and characters are engraved on the packaging paper by laser at present, the laser engraving cost is low, the cost is lower for small-batch processing, but for the common packaging paper, the patterns and the characters are engraved by the laser, and the patterns and the characters are hollowed out, so that the strength of the paper after laser engraving is weakened and the paper is easy to damage.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a laser engraving paper, its accessible laser comes sculpture pattern and characters, and this laser engraving paper bulk strength is high, not fragile after laser engraving moreover.

In order to achieve the above purpose, the solution of the present invention is:

a laser engraving paper comprises a carrying paper, an upper composite glue layer, a metal layer, a lower composite glue layer and a bottom paper which are sequentially compounded from top to bottom.

The metal layer is an aluminum foil or a silver foil or a copper foil or a gold foil.

The metal layer has a thickness of 0.006 to 0.007 mm.

And a resin coating is arranged between the upper composite glue layer and the metal layer.

The resin coating is smeared on the upper surface of the metal layer and is adhered with the upper composite glue layer.

The upper surface of the bearing paper is sprayed with a layer of color coating.

And a transparent protective layer is compounded on the upper surface of the color coating.

The protective layer is a pearly layer or a touch layer or a pearly touch layer sprayed on the upper surface of the outer color coating.

After the scheme is adopted, the utility model has the characteristics of it is following:

1. the laser engraving paper of the utility model can engrave patterns and characters by laser; when the laser engraving paper of the utility model is used for laser engraving, laser emitted by a laser head of a laser engraving machine is irradiated on the bearing paper, and the metal layer resists the laser, so that the laser emitted by the laser head can be fired on the bearing paper without firing the bottom paper, therefore, the laser head is moved according to the required engraved patterns and character information, the required patterns and characters can be engraved on the bearing paper, and the engraved patterns and characters are sunken and have strong third dimension;

2. a laser sculpture paper pass through the metal level and can keep out laser, like this when carrying out laser sculpture, laser can not cause destruction to metal level and bottom paper, makes a laser sculpture paper wholly can not form hollow out construction after laser sculpture, thereby guarantees a laser sculpture paper's bulk strength, makes a laser sculpture paper not fragile.

the paper comprises carrying paper 1, an upper composite glue layer 2, a metal layer 3, a lower composite glue layer 4, bottom paper 5, a resin coating 6, a color coating 7 and a protective layer 8.

Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following embodiments.

The first embodiment is as follows:

as shown in fig. 1, in the first embodiment of the present invention, the laser engraved paper comprises a carrier paper 1, an upper composite glue layer 2, a metal layer 3, a lower composite glue layer 4 and a bottom paper 5 sequentially combined together from top to bottom. The carrier paper 1 and the bottom paper 5 can be kraft paper, double-sided offset paper or paperboard. The metal layer 3 can adopt an aluminum foil or a silver foil or a copper foil or a gold foil, the metal layer 3 can resist laser, the metal layer 3 is preferably a lower-cost aluminum foil in consideration of cost, and the thickness of the metal layer 3 can be 0.006-0.007 mm.

The laser engraving paper can engrave patterns and characters through laser. Specifically, work as a laser sculpture paper when carrying out laser sculpture, the laser that laser engraving machine's laser head sent is beaten on bearing paper 1, and metal level 3 keeps out laser, and makes the laser that the laser head sent can burn and can not burn bottom paper 5 bearing paper 1, removes the laser head according to required glyptic pattern and text information like this, alright carve out required pattern and characters on bearing paper 1, and the pattern and the characters that carve out are sunken, and the third dimension is strong. In addition, the metal layer 3 can resist laser, so that when laser engraving is carried out on the laser engraving paper, the laser cannot damage the metal layer 3 and the bottom paper 5, the laser engraving paper cannot form a hollow structure integrally after laser engraving, the integral strength of the laser engraving paper is guaranteed, and the laser engraving paper is not easy to damage.

Further, the embodiment of the utility model provides an in one, go up and be equipped with one deck resin coating 6 between compound glue layer 2 and the metal level 3, and the laser intensity who sends through the control laser head can make resin coating 6 can not go on by laser evaporation, like this through the resin coating 6 of selecting different colours (like silver, gold, red or yellow etc.), can be so that the corresponding colour of laser sculpture out pattern and characters display on bearing paper 1 to improve the display effect of pattern and characters. The resin coating 6 can be formed by mixing resin paint and pigment, the resin coating 6 is coated on the upper surface of the metal layer 3, and the resin coating 6 is adhered with the upper composite glue layer 2.

Example two:

as shown in fig. 2, the difference between the second embodiment of the present invention and the first embodiment of the present invention is: the embodiment of the utility model provides an in the second, the one deck colour coating 7 has still been sprayed on bearing paper 1 upper surface, and the user can select the colour coating 7 of different colours (like red, yellow, blue, green, purple, orange, coffee etc.) according to self needs, controls a laser engraving paper through the demonstration background of laser sculpture's pattern and characters.

Example three:

as shown in fig. 3, the difference between the third embodiment and the second embodiment of the present invention is: the embodiment of the utility model provides an in three, colour coating 7 upper surface has still compounded the transparent protective layer 8 of one deck, can protect colour coating 7 through protective layer 8, avoids colour coating 7 to drop because of the friction and damages. Wherein the protective layer 8 can be a pearlescent layer sprayed on the upper surface of the color coating 7, which enables the protective layer 8 to produce a pearlescent effect, improving the look and feel of the laser engraving paper; the protective layer 8 can also be a touch layer sprayed on the upper surface of the color coating 7, so that the protective layer 8 has a fluffy touch effect and good hand feeling; the protective layer 8 can also be a pearlescent tactile layer sprayed on the upper surface of the color coating 7, so that the protective layer 8 can generate pearlescent effect and has fluffy tactile impression, and the visual impression and the hand feel of the laser engraving paper are improved.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications made by those skilled in the art should not be construed as departing from the scope of the present invention.
