What are the steps involved in the production process of hanging tag copperplate paper?

The production process of hanging tag copperplate paper mainly includes the following steps:

1、 Material selection

Raw material selection: High quality pulp is usually chosen as the raw material, which is the basis for ensuring paper toughness and printing effect. Pulp can be obtained through chemical, mechanical, or chemical mechanical methods, but the specific method will be selected based on production needs and environmental standards.

2、 Paper making

Beating: Using physical and mechanical methods to process pulp, resulting in fiber cutting, crushing, water absorption swelling, and fine fibrosis, thereby making the fiber size uniform, increasing the surface area, and enhancing strength.

Glue application: Chemical treatment of pulp to obtain resistance to fluid (such as water) penetration.

Adding fillers: Inorganic fillers (such as talcum powder, kaolin, calcium carbonate, titanium dioxide, etc.) and organic polymer chemicals are added to the slurry to improve the paper's opacity, brightness, smoothness, stiffness, dry strength, wet strength, and other properties.

Papermaking: Process the processed pulp into paper using a papermaking device. There are two types of paper making methods: dry paper making and wet paper making. Depending on the paper making method, equipment, and chemicals used, different varieties of paper can be obtained.

3、 Coating processing

Coating: Coating a layer of pigment, resin or other special substance on the surface of the base paper to improve its surface properties, enhance its strength, water resistance, oil resistance, light resistance, radiation resistance, rust prevention and other functions. This is a crucial step in the production of copperplate paper and the reason for its name.

Drying: Put the coated paper into a dryer for drying to ensure that the coating on the surface of the paper is completely dry.

4、 Subsequent processing

Embossing: Place the dried paper into an embossing machine, and after a certain amount of pressure and time, create specific patterns and designs on the surface of the paper. This step can increase the aesthetics and tactile feel of the paper.

Other processing: According to the demand, subsequent processing steps such as cutting and packaging can also be carried out.

In summary, the production process of hanging tag copperplate paper is a complex and delicate process, involving multiple links and steps. Each stage requires strict control over quality and technical parameters to ensure the quality and performance of the final product.
