The main components of hanging tag copperplate paper include copperplate base paper and coating.
1、 Copperplate base paper
Copperplate base paper is the basic material of hang tag copperplate paper, which is usually made by copying bleached chemical wood pulp or partially bleached chemical straw pulp on a paper machine. This type of base paper requires uniform thickness, low elasticity, high strength, and good water resistance to ensure the quality of the coated paper.
2、 Paint
Paint is an important component of hang tag copperplate paper, which is evenly applied to the surface of the copperplate base paper, endowing the paper with characteristics such as whiteness, smoothness, and brightness. The coating is mainly composed of the following components:
White pigment: also known as clay, is one of the main components of coatings. Common white pigments include kaolin, talcum powder, calcium carbonate, titanium dioxide, etc. These pigments have good coverage and whiteness, which can enhance the visual effect of paper.
Adhesive: Adhesives play a role in bonding pigments and paper in coatings. Common adhesives include polyvinyl alcohol, casein, modified starch, synthetic latex, etc. These adhesives can ensure that the coating adheres firmly to the surface of the paper and is not easily peeled off.
Auxiliary additives: In order to improve the performance of coatings and the quality of paper, some auxiliary additives need to be added. These additives include gloss agents, hardeners, plasticizers, dispersants, wetting agents, whitening agents, fluorescent whitening agents, toners, etc. These additives can enhance the glossiness, hardness, flexibility, and other properties of paper, while also making the coating more evenly distributed on the surface of the paper.
In summary, the main components of hang tag copperplate paper are copperplate base paper and coating. Copperplate base paper provides the basic strength and water resistance of paper, while coating endows paper with characteristics such as whiteness, smoothness, and brightness. These components together constitute the excellent quality of hang tag copperplate paper, making it widely used in various fields such as hang tags, labels, packaging, etc.
