Description
Technical field
The present invention relates to the preparation method of a kind of label paper, particularly relate to the preparation method of a kind of aluminized label paper, specifically relate to the preparation method of a kind of beer label aluminized paper.The invention still further relates to a kind of aluminized paper obtained by above-mentioned preparation method.
Background technology
Aluminized paper is made up of body paper, aluminium lamination and coating, and aluminized paper is good due to its glossiness, smoothness and flexibility, and aluminium lamination fastness is high, the printing performance having had and machining property, therefore has been widely used for making beer label.The preparation method of beer label generally comprises paper surface and processes, vacuum aluminum-coated, aluminium lamination topcoating, prints and cut etc. operation, and paper surface processes can be directly at paper surface applying coating, it is also possible to by after compound with basement membrane again row peel off next transfer coated.Along with the renewal of beer industry equipment, production line bottling, labeling speed are increasingly faster, more and more higher to the quality requirement of beer label, not only have paper quality requirement, printing quality requirement, and also labeling adaptive requires and except mark adaptive requirement.In existing beer label acceptance criteria, the two indices that must strictly control is water content and the alkali time of penetration of finished product paper, this is because, the water content of paper is in close relations with the flatness of paper, and the manufacturing process of label is not only affected the biggest by the flatness of paper, and labeling speed is also affected very big, existing standard be Paper Moisture be 5.5 ± 1.5%；And beer bottle needs to soak to remove in alkali lye label after reclaiming, can the alkali permeability that normally take off mark and aluminized paper during wash bottle have the biggest relation, therefore alkali time of penetration is also one needs the strict index controlled, and the standard of client is time of penetration≤120 second, front, time of penetration >=8 second, the back side.
Due to paper through compound drying, the operation such as vacuum aluminum-coated can lose portion of water; in order to ensure the water content of finished product paper; existing technique is to get damp again with steam after topcoating; but steam moisture regain exists, and cost is high, steam is not easily accessible paper and causes the poor problem of paper formation degree; additionally; aluminized paper is easily affected by the humiture in production environment in preparation process; when ambient humidity is high; paper easily makes moist; the vacuum that can affect operation of aluminizing declines; causing shutdown phenomenon, when ambient humidity is low, the easy dehydration of paper causes deformation wing Qu Xianxiang；And the factor that affects aluminized paper alkali permeance property is a lot, in addition to the characteristic of body paper, also closely related with the thickness of each coating, coating quality, for aluminized paper manufacturer, the most wayward to original paper quality characteristic, but the thickness of each coating is the most strictly limited, thus it is nonconforming to often result in the aluminized paper alkali infiltration produced, make that some not de-mark phenomenons occur during brewery's wash bottle, produce adverse consequences.
Summary of the invention
For solve with present on problem, it is an object of the invention to provide the preparation method of a kind of beer label aluminized paper, the method low cost, technique are easily controllable.
It is a further object to provide a kind of aluminized paper obtained by above-mentioned preparation method, this aluminized paper flatness is good, indices all meets the requirement of beer label.
For realizing above first purpose, the preparation method of the beer label aluminized paper of the present invention, including paper surface process, vacuum aluminum-coated, aluminium coated surface coating, it is by carrying out with basement membrane composite transferring coating way that paper surface processes, it is characterized in that: described paper with basement membrane first use before compound solid content be 11%-13%, on machine viscosity be that the acrylic emulsion of 18-20s carries out the back of the body and is coated with, it is 4.5-4.8g/m as applicator roll, wet coating amount that the back of the body uses 300 mesh steel riders when being coated with2, dry temperature be 65-75 DEG C, machine speed be 90-95m/min；Spread during composite transferring is 5-5.5g/m2, dry temperature be 80-90 DEG C, machine speed be 90-95m/min.
After topcoating, paper blushing is easily produced in order to solve beer Special varnish, affect the brightness of body paper, the most more preferably pin the moisture of paper, during the coating of above-mentioned aluminium coated surface, use 210 mesh ceramic rollers coatings, control machine viscosity on coating be 20-22s, wet coating amount be 4.0-4.4g/m2, dry temperature be 60-80 DEG C, machine speed be 90-95m/min.
The spread compound with paper in order to more preferably control laser film, above-mentioned laser film is with paper compound working procedure, and gluing rod preferred hardness is the rubber roll of 60 degree, and the pressure simultaneously controlling upper glue roller is 3.0-3.2kg, and the pressure of composite press roller is 3.8-4.0kg.
In order to ensure that paper moisture before aluminizing is at 5.5g/m2Left and right, prevent moisture the highest cause aluminum-spraying machine vacuum decline and cause shut down, in above-mentioned paper surface treatment process, basement membrane peel off while dry, dry temperature be 60-70 DEG C.
Preferred grammes per square metre 68g/m of above-mentioned paper2, the wet-strength paper of moisture content 4-6%.
In order to enable aluminium coated to have more preferable glossiness and basement membrane more preferably reuse, the preferred BOPP film of basement membrane of above-mentioned composite transfer process.
In order to make beer labeling have laser effect, above-mentioned basement membrane first passes through mold pressing before compound with paper, forms the laser film with special edition laser pattern.
The present invention also provides for a kind of aluminized paper obtained by above-mentioned preparation method, and this aluminized paper includes back coating, ply of paper, glue-line, vacuum aluminium coated layer and finishing coat successively.
Above-mentioned glue-line has special edition laser pattern.
The preparation method of the beer label aluminized paper of the present invention, close the Paper Moisture effective acrylic emulsion back side to paper before paper is combined with basement membrane by employing and carry out back of the body painting, simultaneously by the strict each technological parameter controlling back of the body painting process, ensure that the moisture of paper moisture before aluminizing and finished product all can be maintained at 5.5g/m very well2Left and right, improves the curling resistance of paper, also ensures that being smoothed out of operation of aluminizing simultaneously；It addition, by controlling the paper spread compound with basement membrane and the solid content of back-coating and wet coating amount, it is ensured that the alkali time of penetration of finished paper is within the limits prescribed, it is simple to the wash bottle work of brewery is smooth；The present invention back of the body painting operation is arranged on paper and basement membrane compound before, it is possible to more preferably pin the moisture of body paper, it is ensured that the paper flatness when aluminizing operation, prevent edge jaundice, the phenomenon of blackout, more preferably improve the brightness of aluminium lamination.The preparation method of the present invention, compared with traditional moisture regain technique, has that technique is simple, the feature of low cost, the inventive method the aluminized paper obtained, Paper Moisture stablize controlled, alkali time of penetration suitable, be particularly suitable as beer labeling and use.
