What are the raw materials for PET silver paper?

The raw materials for PET silver paper mainly include the following:

1、 Main substrate

Polyethylene terephthalate (PET):

PET is the main substrate of PET silver paper. It is a polymer material with excellent physical and chemical properties, such as hardness, brittleness, high temperature resistance, waterproofing, oil stain resistance, scratch resistance, and chemical corrosion resistance.

After special treatment, PET material can form a surface with a sub silver luster, hence it is called sub silver paper.

2、 Coating material

Special coating:

In order to enhance the printing adaptability and durability of PET silver paper, a special coating is usually applied to its surface.

These coating materials may include various resins, adhesives, and other additives to enhance the waterproof, oil resistant, and abrasion resistant properties of PET silver paper.

3、 Auxiliary materials

Adhesive:

When using PET silver paper as a self-adhesive label, it is necessary to apply a layer of adhesive to achieve the bonding function.

The selection of adhesive is usually determined based on the usage environment and requirements of the label to ensure that the label can be firmly attached to various surfaces.

Isolation paper:

In the production and storage process of PET silver paper, in order to protect its adhesive surface from contamination or damage, a layer of isolation paper is usually used to cover it.

The isolation paper needs to be torn off before use in order to stick the PET silver paper onto the target object.

In summary, the raw materials for PET silver paper mainly include PET substrate, special coating materials, adhesives, and isolation paper. The selection and processing techniques of these raw materials have a significant impact on the performance and quality of PET silver paper.
