The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
With reference to Fig. 2, show the schematic flow sheet of preparation method first embodiment of a kind of laser packing paper structure of the present invention, comprise step:
Step S210, provide a slim paper as loading material.
Preferably, the grammes per square metre of described slim paper is 28g/m
2To 200g/m
2
Described slim paper can be selected single face art paper, two paper or other thin paper of being coated with, and the embodiment of the invention is preferably 60g/m
2Single face copper paper be loading material.
Step S220, at the surface coated coating of described slim paper.
Described coating is water paint or release material, and preferred, described coating can be selected polyurethanes, acrylic compounds or organic siliconresin material etc.
Preferably, when the surface coated coating of described slim paper, coating effect requirements even compact, and, in order to ensure postorder operation chromatography precision, also comprise step:
The moisture of the described slim paper behind the control coating composition is 3% to 5%.
Step S230, the described slim paper behind the coating composition is carried out laser molding.
Described slim paper behind the coating composition is carried out laser molding, form slim paper with laser effect.
Mould pressing process can adopt existing hard pressure or soft compression technology, and the slim paper through coating composition is carried out laser molding, and the impression striped on the mold pressing version is impressed on the thin paper, forms laser effect.For the laser pattern that obtains clear light and guarantee the alignment precision of postorder operation, need control the technological parameters such as temperature, pressure, speed of the size of radium-shine upper glue roller and compound tense tension force well.
Step S240, the described slim paper vacuum behind the laser molding is plated a metal level.
Described metal level can be aluminium lamination, silver layer, copper layer or other metal level, and described metal layer thickness is preferably 200 dust to 800 dusts.
