Description
Technical field
The invention belongs to polymeric material fields, and in particular to it is a kind of can laser color label packing plastics paper.
Background technique
In daily life, some food, drug, cosmetics equistability are poor, meet light and oxidation easily occurs, decomposes, discoloration
Deng reaction, such as some chemotherapeutics, the anti-of the complexity such as driffractive ring, rearrangement, hydrolysis, polymerization, oxidation, isomerization can occur after dissolution
It answers, the process of above-mentioned reaction can be catalyzed under illumination condition.For another example the photosensitizer of disease treatment, drug during instillation are used for
Visible light can be absorbed and decomposition failure.Therefore, all articles for meeting photo-labile require to be kept in dark place.Under normal conditions, people
The article that is kept in dark place can will be needed to be put into darkroom or the dark place of comparison, or be put into tin paper bag and saved, i.e.,
Make so also to have a small amount of light transmission, destroys the quality for being saved article.Based on the above background, inventor mentions in the present invention
For a kind of plastics package paper that can be used for being protected from light, the plastics package paper can be used for the outer packing of article, can also use in article
In the process be protected from light blocking, for example, cannot use after chemotherapeutics dissolution, or the time point of drug drip containing photosensitizer-like at once
Drop bottle needs are protected from light, and packing plastics paper prepared by the present invention can be used in being protected from light for above situation.Since packing plastics paper adds
Add black pigment that black is presented, multiple articles are difficult to differentiate between after being packed respectively.In order to article packaged by clear differentiation,
Inventor's selection is marked on packing plastics paper using laser.It is printed compared to ink, the conventional tags skill such as chemical attack
Art, Laser marking technology have superiority in various aspects, and laser labelling has the untouchable, feature of environmental protection, permanence, quick and height
Efficiency and with advantages such as high applicabilities.
For carrying out laser marking on plastics, there are mainly three types of forms at present: first is that light plastic part processes depth
Colour code is known；Second is that dark colored plastic product processes light mark；Third is that directly processing colored marking on plastic part.It marks
Different colours, depend on the reaction type occurred in plastic part material, laser equipment parameter adjustment and addition laser
The types of marking additives controls.In addition, the clarity and contrast of marker color, the also material with plastic part itself have
Certain relationship.
Plastic-substrates color for being protected from light is black, if the color of label is white, part light may be made to penetrate,
It is unfavorable for being protected from light.Therefore, present inventor explores and carries out colour-coded on the plastics at fast black base bottom.Colour is marked
Note, at present still in development phase, production application is less.
Patent document CN101003225A discloses a kind of method for making color marker, and the method is on the surface layer of object to be marked
Apply laser beam on material, form oxidation film, colored effect is obtained by film interference, carried out on skin-material three times or with
Upper Essential colour mark, each mark press different Essential colour effects respectively and apply laser beam, and Essential colour colour mixture forms true color effect.
The method not only wants multiple laser marking, outside complex steps, the color effect of mark by after multiple laser irradiation effect it is folded
Realize that technological parameter is more in large-scale production, and color effect is likely to occur inhomogenous in Calais, it is difficult to the case where repeating.
Patent document CN105172403A discloses a kind of method of making color marker, is included in matrix surface and forms presoma
Solution layer；The precursor solution layer is subjected to subregion according to the color of preset tag image；Using laser to different subregions
Precursor solution layer be sintered annealing, form the film layer of different-thickness, the thickness of the film layer and the presoma
The thickness of solution layer meets preset relation；The film layer of the different-thickness is shown as different colors, and forms described default
Tag image.The above method realizes that difficulty is big, and resource consumption is big, at high cost, is difficult to put into large-scale production.
Patent document CN106566068A disclose it is a kind of can laser color label polymer composition, the patent is in group
It closes in object and is added to 0.05-2 parts of laser marking powder and 0.1-10 parts of warming substance, principle makes through laser marking process
The heat of middle generation makes warming substance the reactions such as thermal decomposition, oxidation occur at a certain temperature to destroy the starting substance knot
Structure generates a kind of novel substance, generates a kind of new color, to realize that color laser marks.But the selection of warming substance is very harsh,
It is of limited application.Therefore, the efficient color laser mark for simple, there is presently no relatively good methods.
In addition, carrying out laser labelling on plastic paper, a critically important problem is: portion, laser irradiating part branch office generates heat
Amount, usual plastic paper is relatively thin, easily causes local thermal contraction, generates the undesirable conditions such as gauffer aggregation, does not advise so that label is whole
Then, resolution ratio seriously reduces.Patent document CN105121173A, which discloses one kind, to be had resistance to chemical reagents, wear resistance and is suitable for height
Film is written in the information of the white laser mark of contrast.Although improving the problem of membrane laser marks local shrinkage,
Mode is excessively complicated, needs to prepare information write-in film and reads auxiliary layer, and makes as the color developing agent in Myocardial revascularization bylaser
Colour development material is but strong with resistance to chemical reagents and structural strength is big under shaped state without directly forming write-in film layer
Transparent plastic material is kneaded.It is excessively high that so complicated cumbersome preparation process certainly will will lead to production cost, consumes after putting goods on the market
The degree of recognition of person is not high.
For overcome the deficiencies in the prior art, simplify preparation step, reduce production cost, while realizing on plastic paper again
The purpose of color laser label is carried out, in this application, applicant passes through specific selection plastic material, color pigment and addition
Agent makes each ingredient work in coordination, i.e. will not be since locally heat absorption being heat-shrinked phenomenon plastic paper occurs, also during laser marking
It can clearly show the label to be presented.

It is remaining to prepare raw material and preparation method is same as Example 1.Laser labelling is carried out using C02 laser marking machine, laser pulse repeats
Frequency is 35KHz, and pulsewidth 0.5us, mark speed is 20mm/s, and mark electric current is 10A.
The preparation of 13 plastic paper 13 of embodiment
1 part and 2 parts of color pigment lithopone of black pigment furnace black in the present embodiment, remaining prepares raw material and preparation side
Method is same as Example 1.Laser labelling, laser pulse repetition frequency 35KHz are carried out using C02 laser marking machine, pulsewidth is
0.5us, mark speed are 20mm/s, and mark electric current is 10A.
Influence of the effect example color pigment to laser labelling
After plastic paper prepared by embodiment 1 and 10-13 as described above condition progress laser labelling, mark
Effect is as shown in the table:
Influence of 3 color pigment of table to laser labelling
| Black pigment and color pigment mass ratio | Mark effect | Resolution ratio | |
| Embodiment 1 | 1:3 | Pattern color is clear, neat in edge | ++++ |
| Embodiment 10 | 1:1.6 | Pattern color clearly becomes clear, neat in edge | +++++ |
