The main components of transparent thermal label paper usually include the following parts:


1、 Substrate

The substrate of transparent thermal sensitive label paper is generally made of high-strength and high stability native cellulose material. Native cellulose is a natural polymer compound extracted from plant cell walls, which has high strength and stability, and is the basic supporting part of label paper.


2、 Coating

The coating is a key component of transparent thermal sensitive label paper, which determines the thermal sensitivity and printing effect of the label paper. The coating is mainly composed of the following components:

Thermally sensitive infectious material: This is a key substance for achieving thermal printing. When stimulated by heat, the dye undergoes chemical changes, resulting in the appearance of color.

Resin: Resin acts as an adhesive in coatings, fixing thermosensitive materials and other additives to the surface of paper.

Stabilizers: Stabilizers are used to improve the stability and durability of coatings, preventing dyes from fading or deteriorating in high temperature or humid environments.


3、 Glue (adhesive)

Adhesive is another important component of transparent thermal sensitive label paper, which determines the viscosity and adhesion of the label paper. Glue is usually made of acrylic acid lotion, with good viscosity and strong stability. This allows the label to be firmly attached to various surfaces while not easily falling off or curling.


4、 Other additives

In addition to the above main ingredients, transparent thermal label paper may also contain some other additives, such as plasticizers, anti-aging agents, etc., to improve the flexibility and durability of the paper.


To sum up, the main components of transparent thermosensitive label paper include substrate (raw cellulose material), coating (thermosensitive infectious material, resin, stabilizer, etc.) and glue (acrylic lotion). These components together constitute the basic structure of transparent thermal sensitive label paper and determine its thermal sensitivity and printing effect.
