What parts does the structure of colored copperplate label paper include?

The structure of colored copperplate label paper usually includes the following key parts:

1. Surface material (surface material)

Material: The surface material of color copperplate label paper is mainly copperplate paper, which is a coated printing paper with smooth surface, high whiteness and good ink-absorbing performance.

Features: The surface material determines the printing effect, gloss and color expression of the label. Because of its excellent printing performance, color coated paper is often used to make labels that require high color reproduction and gloss.

2. Adhesive

Action: The adhesive is a key part of the connection between the surface material and the backing paper, which ensures that the label can be firmly attached to the target object.

Types: There are many types of adhesives, such as rubber-based, acrylic and silicone. Different types of adhesives have different performance characteristics, such as temperature resistance, chemical resistance, aging resistance, etc. For colored copper label paper, the adhesive suitable for its application environment is usually selected.

3. Backing paper

Function: The backing paper is the supporting part of the label, which provides enough strength and stability to make the label difficult to deform or damage during transportation, storage and use.

Material: The backing paper is usually made of paper materials, such as Glassine paper, white single copper release paper, etc. These materials have good internal strength and light transmittance and are suitable as the base paper for self-adhesive labels.

4. Coating (optional)

Function: In some cases, in order to improve the printing effect of the label, increase gloss or improve wear resistance, a special coating may be added to the surface of the surface material.

Type: The type and formulation of the coating will be based on the specific needs, such as UV coating, water-based coating, etc.

5. Back paint (optional)

Function: The back coating is mainly used to improve the adhesion between the base paper and the adhesive to prevent the adhesive from penetrating into the bottom paper and affecting its performance.

Features: The backcoat is usually a thin coating that has little impact on the overall performance of the label, but can be very important in specific application environments.

In summary, the structure of color copperplate label paper mainly includes the surface material (coated paper), adhesive, backing paper and optional coating and back coating. These parts together determine the performance characteristics and application range of the label. In practical applications, appropriate materials and processes need to be selected according to specific needs to make color copperplate label paper.
