What is the structure of the three heat-proof label paper?

The structure of the heat-resistant label paper is usually divided into three layers, each layer has its specific functions and characteristics. The following is a detailed explanation of the structure of the three heat-resistant label paper:

1. Surface layer (thermal paper layer) :

The surface layer is the part directly in contact with the print head, and is also the main area for information printing and display. It usually consists of heat-sensitive paper, which when heated produces a chemical reaction that reveals the printed text or image.

The characteristics of surface thermal paper directly affect the printing effect and quality. High quality thermal paper provides clear, long-lasting printing results with good wear resistance to cope with wear and tear during daily use and transportation.

2. Middle layer (viscose layer) :

The middle layer is located between the surface layer and the bottom layer, and mainly plays a bonding role. It is usually made of single-sided PET (polyester) or special paper with self-adhesive, which has good viscosity and stability to ensure that the label paper sticks firmly on a variety of substrates.

The quality of the adhesive layer is crucial to the adhesive effect and durability of the label paper. The high-quality adhesive layer can maintain a stable viscosity in different environments to avoid the label falling off or warping.

3. Bottom layer (Glasin release layer) :

The bottom layer is the bottom layer of the label paper, usually made of Glasin release paper. Glasin release paper has excellent release properties and can be easily peeled off when the label paper is attached to the substrate without causing damage to the surface or adhesive layer.

The existence of the bottom layer not only protects the viscosity of the adhesive layer during storage and transportation, but also facilitates the use of label paper. The user only needs to gently uncover the bottom layer and paste the label paper to the desired location.

In summary, the structure of the three thermal label paper includes three layers of the surface layer (thermal surface paper layer), the middle layer (adhesive layer) and the bottom layer (Grasin release paper layer). Each layer has its own specific functions and characteristics, which together constitute three heat-proof label paper with waterproof, oil-proof, scratch-proof and other characteristics. The design of this structure enables the heat-sensitive label paper to maintain stable printing effect and paste performance in a variety of harsh environments, and is widely used in logistics, retail, medicine and other fields.
