Embodiment 1

[0018] A method for correcting the curling of aluminum-coated paper for beer labels. First, prepare the coating according to the weight percentage of the following components: polyethylene glycol-200 20%, ethylene glycol dimethyl ether 3%, diethylene glycol isooctyl 5% ether, 2% boric acid ester, 70% water; then use a 165-mesh gravure roll coater to coat the backside of the aluminized paper with the coating prepared as described above, and the wet coating amount is controlled at 6.0g / m 2 ; The paper was dried in a drying oven at 50°C for 15 seconds, and then coiled to obtain an aluminized paper with good flatness. The moisture content of the aluminized paper after coating and correction is 4.0 wt%, and the temperature and humidity range of the anti-curling of the aluminized paper is a temperature of 15-60° C. and a relative humidity of 50-85%.

Embodiment 2

[0020] A method for correcting the curling of aluminized paper for beer labels. First, the coating is prepared according to the weight percentage of the following components: polyethylene glycol-200 30%, ethylene glycol dimethyl ether 10%, diethylene glycol isooctyl 5% ether, 5% boric acid ester, 50% water; then use a 165-mesh gravure roll coater to coat the backside of the aluminized paper with the coating prepared as described above, and the wet coating amount is controlled at 6.0g / m 2 ; The paper was dried in a drying oven at 50°C for 15 seconds, and then coiled to obtain an aluminized paper with good flatness. The moisture content of the aluminized paper after coating and correction is 3.5 wt%, and the temperature and humidity range of the anti-curling of the aluminized paper is a temperature of 15-60° C. and a relative humidity of 30-50%.

Embodiment 3

[0022] A method for correcting the curling of aluminum-coated paper for beer labels, first formulating the coating according to the weight percentage of the following components: polyethylene glycol-200 40%, ethylene glycol dimethyl ether 5%, diethylene glycol isooctyl 5% ether, 5% boric acid ester, 45% water; then use a 165-mesh gravure roll coater to coat the backside of the aluminized paper with the coating prepared as described above, and the wet coating amount is controlled at 6.0g / m 2 ; The paper was dried in a drying oven at 50°C for 15 seconds, and then coiled to obtain an aluminized paper with good flatness. The moisture content of the aluminum-coated paper after coating and correction is 3.5 wt%, and the curl-resistant temperature and humidity range of the metal-coated paper is a temperature of 5-80° C. and a relative humidity of 30-65%.

Abstract

The invention belongs to the technical field of beer label aluminized paper and particularly relates to a method for correcting beer label aluminized paper crimpiness. The back surface of the beer label aluminized paper is coated with a layer of paint, and the paint is prepared from the following ingredients in weight percentage: 3% to 50% of polyethylene glycol-200, 3% to 10% of glycol dimethyl ether, 3% to 10% of diethylene glycol isooctyl ether, 1% to 10% of boric acid ester and 40 to 90% of water. The back surface of the aluminized paper is evenly coated with the paint in a gravure roller coating mode, then dried by hot air and reeled and finally kept flat. The method disclosed by the invention can improve moisture content in the beer label aluminized paper, corrects aluminized paper crimpiness, enables the aluminized paper to be kept flat and widens an application range of the aluminized paper to environmental temperature and humidity.

Description

technical field [0001] The invention belongs to the technical field of aluminized paper for beer labels, and in particular relates to a method for correcting the curl of the aluminized paper for beer labels. Background technique [0002] With the continuous updating of equipment in the beer industry, the bottling and labeling speed of the production line is getting faster and faster, and the quality requirements for beer labels are also getting higher and higher. Wine labels require that it should have good stiffness and flatness after printing, so that the labeling machine can label normally, so that the label can be pasted on the bottle wall smoothly and uniformly, and the process quality of labeling can be improved. If the label is obviously curled, there may be failure phenomena such as wrinkled label, broken label, dropped label, warped label, crooked label, etc. Therefore, it is very important to correctly understand and control the curling performance of aluminized pa...
