Background technology
Traditional packing paper product, as packings such as cigarette case, wine box, medicine boxs, concavo-convex picture and text on it are to adopt corrosion zine plate or copper coin usually, making the negative and positive cover die carries out cramping to paper product and extrudes and form, its effect is more coarse, fuzzy, not attractive in appearance, and reprint is copied easily, and many producers all attempt to utilize it to improve the class of product and take into account false proof effect, but but can't solve above-mentioned deficiency, become a difficult problem always.
For many years, industry member attempts to seek a kind of new mode, so that obtain a kind of packing paper product with exquisite picture and text attractive in appearance, one can be so as to improving the class of product, and two can be used as anti-false sign plays the effect of distinguishing that product is true and false.But people do not search out so a kind of method yet so far.
Summary of the invention
At present importantly obtain a kind of new packing paper product by method of the present invention.It is engraved in fine picture and text on the steel plate by laser, is made into punching block, utilizes to press to scald to make paper product surface extrusion form meticulous concavo-convex literal or pattern.
Method of the present invention combines and shows novelty owing to miniature carving punching block and packing paper product press being scalded processing.
Moreover this method only forms fine concavo-convex picture and text on the paper product surface and shows its originality again.
So the technical director who the objective of the invention is to provide a kind of essence a kind ofly can form the method for fine concavo-convex picture and text and obtain packing paper product obtained by this method realizing on the paper product surface.
In addition, the present invention also aims to the packing paper product that obtained, its picture and text are concavo-convex even, complete clear.
Method of the present invention is realized by following steps:
(1) going out trickle literal or pattern with laser engraving on steel plate, be made into punching block, can be intaglio plate, also can be relief printing plate;
(2) punching block is contained on the moulding press, unidirectional exerted pressure and regulate and control the punching block temperature in the paper product surface, make the paper product surface form trickle concavo-convex picture and text.
Method is preferably, and above-mentioned applied pressure is controlled at 15kg/cm
2-30kg/cm
2, have concave-convex sense to guarantee the picture and text that form on paper product surface, and the unlikely generation fracture of paper product is damaged; Be more preferably, above-mentioned applied pressure is controlled at 20kg/cm
2-25kg/cm
2So that picture and text are concavo-convex even, complete clear, exquisite attractive in appearance.
Desirable method is, above-mentioned punching block temperature be adjusted in 0 degree centigrade-140 degrees centigrade.To guarantee that paper product keeps normal physical property, the pretty good position of concavo-convex picture and text; Better method is, the regulation and control of above-mentioned punching block temperature, according to different types of paper product, with reference to the following table temperature adjustment:
Paper product kind temperature controlling range
10 ℃ of art post paperboards--80 ℃
5 ℃ of glass paperboards--60 ℃
10 ℃ of pearly-lustre paperboards--70 ℃
15 ℃ of aluminum foil composite papers--120 ℃
20 ℃ of organic film extrusion coating papers--50 ℃ so that the concavo-convex shaping of picture and text is obviously even, clear, complete.
The best way is that the thickness of above-mentioned paper product is chosen 150g/m
2-350g/m
2, to guarantee that paper product can not rupture or concavo-convex shapeless; Best paper product thickness is chosen 200g/m
2-300g/m
2, the concavo-convex picture and text that paper product surface pressurized is formed are clear, complete.
The specific embodiment
Be the embodiment of the inventive method below:
Adopt laser carving out the picture and text of line thickness between 0.01mm-1mm on the steel plate, make punching block.Punching block can be made intaglio plate or relief printing plate according to user's requirement.Form in the process of picture and text on the paper product surface, according to different paper products, choose the following parameters value, the effect of acquisition is also listed in the table.
