Problems solved by technology

[0003] Since the paper will lose part of its moisture after compound drying, vacuum aluminum plating and other processes, in order to ensure the moisture content of the finished paper, the existing process is to use steam to regain moisture after top coating, but the cost of steam regaining moisture is high, and steam is not easy to enter the paper In addition, the aluminum-coated paper is easily affected by the temperature and humidity in the production environment during the preparation process. When the ambient humidity is high, the paper is prone to moisture, which will affect the vacuum degree of the aluminum-plating process and cause shutdowns. , when the ambient humidity is

Example Embodiment

[0019] Example 1

[0020] Such as figure 1 Shown is the aluminized paper for beer labels of the present invention. The aluminized paper is back coating 1, wet-strength paper layer 2, adhesive layer 3 with special laser pattern, aluminized layer 4 and surface from bottom to top. Coating 5.

[0021] The preparation method of the aluminized paper of the present invention is as follows figure 2 As shown, it includes: (1) making a laser film, using the production method of UV duplicating a seamless laser effect plate roll to mold the BOPP transfer base film to obtain a laser film with a beer trademark special edition laser pattern; (2) paper Back coating, using acrylic emulsion with a solid content of 11% and a viscosity of 18-20s on the wet strength paper (68g / m 2 , Moisture 4-6%) Back-coating on the back, using a 300-mesh steel roller as the coating roller when back-coating, the wet coating amount is 4.5g / m 2 , The drying temperature is 65-70℃, the machine speed is 90m / min, and the ...

Abstract

The invention provides a preparation method of aluminized paper for beer labels. The preparation method comprises the steps of paper surface treatment, vacuum aluminizing and surface coating of an aluminized layer, wherein the paper surface treatment is carried out by compounding with a base membrane to transfer a coating, an acrylic emulsion of which the solid content is 11-13% and the machine viscosity is 18-20s is adopted to perform back coating before the compounding of paper and the base membrane, and during the back coating, a 300-mesh steel roll is used as a coating roll, the wet coating quantity is 4.5-4.8g/m<2>, the drying temperature is 65-75 DEG C and the machine speed is 90-95m/min; and during compound transferring, the gluing quantity is 5-5.5g/m<2>, the drying temperature is 80-90 DEG C, and the machine speed is 90-95m/min. Compared with a conventional dampening process, the preparation method provided by the invention has the characteristics simple process and low cost; and the aluminized paper obtained by the method provided by the invention is stable and controllable in paper water content and appropriate in alkali penetration time, and is particularly suitable to be used as beer labels. The invention also provides the aluminized paper obtained by the preparation method.

Description

technical field [0001] The invention relates to a method for preparing label paper, in particular to a method for preparing aluminized label paper, and more particularly to a method for preparing aluminized paper for beer labels. The present invention also relates to an aluminized paper obtained by the above preparation method. Background technique [0002] Aluminum-coated paper is composed of base paper, aluminum layer and coating. Aluminum-coated paper has been widely used because of its good gloss, smoothness and softness, high fastness of aluminum layer, good printing performance and mechanical processing performance. Used to make beer labels. The preparation method of beer labels generally includes paper surface treatment, vacuum aluminum plating, aluminum surface coating, printing and slitting and other processes. Paper surface treatment can be directly coated on the surface of the paper, or it can be peeled off after laminating with the base film. to transfer the co...
