How are the materials of each layer of PET matte silver thermal paper combined with each other?

The materials of each layer of PET matte silver thermal paper are combined through specific processes. The following is a detailed analysis of its structure:

1、 Structure of PET matte silver thermal paper

PET matte silver thermal paper usually consists of three layers:

Noodle paper: This is the carrier of label printing content and also the part that comes into direct contact with the user. The facial paper is made of PET (polyester film) and covered with a uniform layer of silver special coating on the surface. This coating not only gives the paper a matte silver texture, but also gives it a high-end and professional appearance. At the same time, this coating is also the key to achieving thermal printing technology. When the thermal print head heats the surface of the paper, the coating undergoes a chemical reaction, generating clear images and text.

Adhesive layer: located between the surface paper and the base paper, it plays a role in adhesive fixation. Adhesive layers usually use strong adhesives to ensure that labels can be firmly attached to various surfaces.

Bottom paper: This is a layer of paper that protects the adhesive layer. Before printing and pasting labels, the bottom paper serves to support and protect the adhesive layer. After printing is completed, users can easily tear off the backing paper and paste the label onto the target object.

2、 The combination method of materials in each layer

The combination of face paper and adhesive layer: The back of the face paper is coated with adhesive, which is evenly applied to the back of the face paper during the manufacturing process and tightly bonded to the adhesive layer. This combination ensures that the labels will not fall off or delaminate during the printing and pasting process.

The bonding between adhesive layer and base paper: The bonding between adhesive layer and base paper is also achieved through adhesive. During the manufacturing process, the adhesive is applied to one side of the base paper and tightly adheres to the adhesive layer. This combination method not only ensures the stability of the adhesive layer, but also allows users to easily separate the label from the backing paper when tearing it open.

3、 Combining technology

The various layers of PET matte silver thermal paper are combined with each other through specific processes, including coating, lamination, cutting, etc. During the coating process, the adhesive is evenly applied to the back of the face paper and one side of the base paper; During the composite process, the face paper, adhesive layer, and base paper are tightly bonded together through methods such as pressing; During the cutting process, the entire PET matte silver thermal paper is cut into the shape and size of individual labels according to user requirements.

In summary, the materials of each layer of PET matte silver thermal paper are combined through adhesives and specific processes. This combination ensures the firmness, stability, and ease of tearing of the label, enabling it to perform excellently in various application scenarios.
