What are the main steps for producing PET matte silver thermal paper?

The main steps for producing PET matte silver thermal paper include the following steps:

1、 Raw paper preparation

Choose PET substrate: PET (polyethylene terephthalate) is a commonly used label paper substrate with good mechanical properties, heat resistance, and chemical stability.

Quality inspection: Ensure that the flatness, strength, and thickness of PET substrate meet production requirements to ensure subsequent processing and printing effects.

2、 Coating preparation and coating

Preparation of matte silver coating: The matte silver coating is a key component of PET matte silver thermal paper, typically composed of special chemicals that can undergo chemical reactions and produce color changes when heated.

Uniform coating: Apply the prepared matte silver coating evenly onto the PET substrate. This step requires precise control of the thickness and uniformity of the coating to ensure consistency in the printing effect.

3、 Drying and solidification

Drying treatment: After coating is completed, the paper needs to be dried to remove solvents and moisture from the coating, so that the coating can firmly adhere to the PET substrate.

Curing treatment: Further curing the coating by heating or other means to improve its adhesion and durability.

4、 Quality inspection and packaging

Quality inspection: Conduct quality inspection on the produced PET matte silver thermal paper, including checking the flatness of the paper, the uniformity of the coating, the printing effect, and durability.

Packaging and labeling: Pack qualified PET matte silver thermal paper and label and store it according to customer requirements. Packaging materials should be selected to be moisture-proof and dust-proof to ensure the quality of the product during storage and transportation.

5、 Other possible steps

Add protective layer: In order to improve the durability and adhesion of PET matte silver thermal paper, sometimes an additional protective layer is applied on top of the matte silver coating. The protective layer can absorb some of the light that causes chemical reactions in the thermal sensitive coating, slow down the deterioration of the printing paper, and protect the thermal sensitive components of the printer from damage.

Slitting and cutting: According to customer needs, PET matte silver thermal paper is cut and cut to meet different size and shape requirements.

Throughout the entire production process, it is also necessary to closely monitor the operating status of equipment and the use of materials, and promptly identify and solve problems. At the same time, it is also necessary to comply with relevant environmental regulations and safety rules to ensure the environmental protection and safety of the production process.
