Problems solved by technology

In recent years, with the thinning of these products, the label paper is also required to be thinner, but if the label paper is thinned, it is easy to produce wrinkles or air bubbles when pasting, and sometimes it will lead to an increase in the total thickness. After the increase, the label paper is easily damaged and cannot meet the high temperature requirements, and most ordinary label paper does not have anti-counterfeiting functions

Embodiment 1

[0021] Such as figure 1 As shown, a kind of anti-counterfeiting label paper production process of the present embodiment is characterized in that, comprises following process step:

[0022] (1) Raw material preparation: The raw materials for the production of the anti-counterfeiting label paper include the following mass fractions: 50 parts of long-fiber wood pulp, 35 parts of short-fiber wood pulp, 1.5 parts of wet strength agent, 40 parts of coated latex, and 2 parts of sizing agent , 0.3 parts of retention aid, 8 parts of metallized paper, wherein the wet strength agent is specifically polyester, the sizing agent is specifically alkene-based succinic anhydride, the retention aid is specifically silica gel, and the coating latex is specifically is propionate;

[0023] (2) beating treatment: long-fiber wood pulp and short-fiber wood pulp are added to the pulper for crushing treatment and then pumped into the pulper for beating. The degree of beating is 20SR, and the beating ...

Embodiment 2

[0029] Embodiment 2: all the other are identical with embodiment 1, and difference is that beating degree is 25SR in described step (2), and beating concentration is 5%, and drying temperature is 110 ℃ in described step (3), and calender roll surface The temperature is 120°C, the coating concentration in the step (4) is 25%, the drying temperature in the step (5) is 120°C, and the drying time is 35min, and the anti-counterfeiting calendering pressure in the step (6) 400kN / m 2 , after calendering, color printing is carried out on it, wherein the calendering time is 1.2h, and the roller surface temperature is 150°C.

Embodiment 3

[0030] Embodiment 3: all the other are identical with embodiment 1, and difference is that beating degree is 30SR in described step (2), and beating concentration is 5%, and drying temperature is 110 ℃ in described step (3), and calender roll surface The temperature is 150°C, the coating concentration in the step (4) is 30%, the drying temperature in the step (5) is 130°C, and the drying time is 40min, and the anti-counterfeiting calendering pressure in the step (6) 400kN / m 2 , after calendering, color printing is carried out on it, wherein the calendering time is 1.5h, and the roller surface temperature is 180°C.

[0031] After the above process steps, the PE heat shrinkable film sample was taken out, and the following data were obtained:

[0032]

[0033]

[0034] It can be seen from the above data that the product obtained by the present invention has good wet strength, and through reasonable manufacturing process and materials, it has excellent tear resistance, can ...

Abstract

The invention discloses a production technology for anti-counterfeit label paper and relates to the technical field of label paper production. The production technology comprises seven processes of raw material preparation, pulping treatment, body paper-making treatment, coating treatment, drying treatment, anti-fake calendaring treatment and packaging storage. According to the invention, wet strength agent and sizing agent are added, so that the wet strength and de-lamination resistance strength are high; through the reasonable manufacturing technique and material, the label paper has excellent tear resistance, can meet the strength requirements in subsequent process and practical use and has excellent surface smoothness and printing property; through the anti-fake calendaring treatment, the produced label paper has an anti-counterfeit function and is worthy of popularization.

Description

technical field [0001] The invention relates to the field of label paper production technology, in particular to a production technology of anti-counterfeit label paper. Background technique [0002] In daily life, label paper can often be seen pasted on glass products or electronic products. For example, batteries used in smartphones, tablet PCs, etc. are generally affixed with labels on which the manufacturer's name, product information, precautions, etc. are printed. In recent years, with the thinning of these products, the label paper is also required to be thinner, but if the label paper is thinned, it is easy to produce wrinkles or air bubbles when pasting, and sometimes it will lead to an increase in the total thickness. After the increase, the label paper is easily damaged and cannot meet the high temperature requirements, and most ordinary label paper does not have anti-counterfeiting functions. Contents of the invention [0003] The problem to be solved by the ...
