There are various surface treatment methods for copperplate paper adhesive labels, and the following are some common methods:

1、 Film coating process

Application: Widely used in label production, especially in copperplate paper adhesive printing.

Principle: Paste transparent plastic film onto the surface of printed materials through hot pressing.

Function: Protect stickers, increase gloss, and extend service life. In addition, the laminated label is not easily damaged if there are indentations.

2、 Oil process

Application: Relatively less used, mainly because self-adhesive labels are usually printed for convenience and have high oiling costs.

Principle: Replace the ordinary oil of the self-adhesive printing machine with glossy ink for printing production.

Function: A surface decoration of self-adhesive, which can enhance the added value of the product.

3、 Hot stamping/silver stamping process

Application: Less commonly used, with complex processes and high costs, usually used for logos, labels, trademarks, etc.

Principle: Using the principle of hot press transfer, the aluminum layer in the electroplated aluminum is transferred to the surface of the substrate, forming a special metallic effect.

Function: Enhance the surface decoration of adhesive labels and increase the added value of products; Simultaneously possessing high anti-counterfeiting performance.

4、 Die cutting process

Application: Widely used in irregular adhesive labels.

Principle: Use a die-cutting blade for die-cutting, so that the shape of the printed product is no longer limited to straight edges or right angles.

Function: Helps with product shaping, making the label more in line with the shape and requirements of the product.

5、 Indentation process

Application: Widely used for pressing marks or leaving curved grooves on adhesive paper.

Function: Convenient for the use of stickers, especially when folding or bending labels, indentation can provide better folding effect and stability.

6、 Drilling process

Application: Not commonly used, but may be used in certain specific needs.

Principle: Use punching equipment to punch holes on adhesive paper.

Function: It is convenient to use stickers, such as hanging hole labels, which can be easily hung on shelves or display racks.

7、 Line drawing process

Application: Widely used, especially in situations where auxiliary molding or cutting is required.

Principle: Use a line drawing machine to draw lines on adhesive paper.

Function: Help products form faster and provide accurate reference lines for subsequent cutting or folding.

In summary, there are various surface treatment methods for copperplate paper adhesive labels, each with its unique application scenarios and functions. In practical applications, suitable surface treatment methods can be selected based on specific needs and product characteristics.
