What are the main components of PET thermal matte silver paper?

PET thermal matte silver paper is mainly composed of the following key components:

Base layer (PET layer): The basis of PET thermal matte silver paper is polyethylene terephthalate (PET) material. PET is a widely used plastic material known for its excellent physical and chemical properties. It has good high temperature resistance, water resistance, oil resistance and chemical stability, which makes PET an ideal choice for making high-quality label materials.
Thermosensitive coating: A special thermosensitive coating is applied to the PET substrate, which is the key to achieving the thermal printing function. This coating can react chemically under the heating of the thermal printer to show the required images and text. Thermal printing technology has the advantages of fast speed, low noise and clear printing, which is very suitable for fast printing of various labels.
Matt silver treatment layer: The matte silver treatment layer is the source of the unique appearance of PET thermal matte silver paper. This treatment makes the surface of the label paper present a matte silver effect, which is not only beautiful and generous, but also has certain anti-reflection and scratch resistance. The matte silver treatment layer is usually achieved through a special coating process, which can ensure that the label paper can maintain good visual effects in various environments.

Adhesive layer: A layer of adhesive is applied on the back of the PET substrate to stick the label paper to the target object. This layer of adhesive needs to have good adhesion and removability to ensure that the label can be firmly attached to the surface of the object, and can also be easily removed without leaving residue when needed.
Bottom paper layer: In order to protect the adhesive layer from contamination or damage, a layer of bottom paper is also attached to the back of the adhesive layer. This layer of bottom paper plays a protective role before the label paper is used. When using it, just tear it off to expose the adhesive layer for sticking.
In summary, PET thermal matte silver paper is mainly composed of key components such as PET substrate layer, thermal coating, matte silver treatment layer, adhesive layer and bottom paper layer. These components together give PET thermal matte silver paper excellent physical and chemical properties and unique appearance effects, enabling it to perform excellent performance in various application scenarios.
