What are the main raw materials of self-adhesive copperplate label paper?

The main raw materials of self-adhesive copper plate label paper mainly include the following aspects:

First, the surface material

Coated paper: Coated paper is one of the most commonly used surface materials in self-adhesive label paper, and it is also the main material of self-adhesive copperplate label paper. It is made of cellulose fibers and the surface is specially treated to give it good flatness and printing properties. Coated paper is characterized by high whiteness, good gloss, and bright pattern and text printing effect, which is very suitable for high-quality label production.

Second, adhesive

Adhesive: In a self-adhesive label, the adhesive is a key part of the connection between the surface material and the backing paper. It is responsible for firmly attaching the label to the object that needs to be identified. The type and performance of the adhesive will affect the adhesive effect and durability of the label. For self-adhesive copperplate label paper, adhesives suitable for copperplate paper surface materials are usually used to ensure the paste effect and overall quality of the label.

Third, the backing paper

Backing paper: The backing paper is the supporting material of the self-adhesive label, usually silicon coated protective paper. It is used to protect adhesives from sticking or contamination during storage and transportation. When labels need to be used, they can be easily removed from the backing paper without damaging the adhesive or the label itself.

Fourth, other auxiliary materials

In the production process of self-adhesive copper plate label paper, some other auxiliary materials may also be used, such as ink, laminating materials, etc. The choice and use of these materials will also affect the final quality and performance of the label.

In summary, the main raw materials of self-adhesive copperplate label paper include copperplate paper surface, adhesive, backing paper and other auxiliary materials. The selection and combination of these materials is crucial to the quality and performance of self-adhesive labels. In the production process, the appropriate raw materials and process parameters need to be selected according to the specific application requirements and the use environment of the label.
